What are lab-grown diamond necklaces?

A diamond necklace is the stuff of dreams. You’ll find it mentioned in literature and the movies as the ultimate gift. When you give someone a diamond necklace, it is a sign of the importance and value that you place on your relationship with the recipient. Buying a diamond necklace for yourself is also the ultimate indulgence for anyone who likes to treat themselves to something extraordinary.

Diamonds have always held a mystique. They have been coveted for centuries for their extraordinary beauty and treasured by generations of the nobility, royalty, celebrity set, and those wealthy enough to afford them.

They are a girl’s best friend. They are ‘forever.’

The history of the diamond necklace

It is thought that diamonds were first discovered and traded in India as far back as the fourth century BC. At that time, only the fabulously wealthy upper classes in India could afford them. Still, diamond trading gradually made its way along the Silk Road caravan trading routes to Western Europe. By the 1400s, diamonds were being purchased and worn by Europe’s elite.

Centuries later, deposits in Brazil and, importantly, South Africa led to an increase in both demand and output. Diamond mining expanded further with deposits found in Australia, Canada, and other parts of Africa, such as Botswana.

The diamond industry has marketed itself brilliantly over the decades. As a result, we have been primed to think of diamonds in connection with love, engagements, marriage, and special anniversaries.

The diamond is still the most popular gemstone of choice for these and a host of other important life celebrations. DeBeers may have revolutionized the diamond business with their ‘A diamond is forever’ tagline. However, the use and significance of diamonds date back to the ancient Romans, who gave diamonds as friendship or betrothal gifts.

To this day, the gift of a diamond is full of meaning. It is the symbol of longevity, luxury, and love. They are found in all kinds of jewelry, including engagement rings, earrings, bracelets, and all types and designs of necklaces, of course. And while mined diamonds today are ubiquitous, they are still very expensive to buy.

Only about 20% of all mined diamonds are big enough or of sufficient quality to find their way into jewelry. The rest are used in drills and for other engineering purposes because of a diamond’s unequaled durability and hardness. For this reason, too, high-quality mined diamond jewelry is very expensive.

Environmental impact of natural diamond necklaces

Most diamond mines yield only one part diamond to 1 million parts host rock. That’s an extraordinary fact – and it means that there is an enormous and expensive output of human resources, equipment, and resources for very little return in the discovery of an actual diamond – let alone one of jewelry quality.

That’s what makes them so costly, of course. Diamonds are relatively rare and exorbitantly expensive to mine. The impact of diamond mining on the environment has been widely documented. It has led to the destruction of vast areas of land and forests across the world – and to the exploitation of poorly paid workers forced to work in dangerous conditions.

Lab-grown diamond necklaces – the real deal, for less

But did you know that you can get a real diamond at a much lower cost without environmental damage and poor working conditions? You can with lab-grown diamonds.

A lab-created diamond is just as real as a mined one. And thus, a lab-grown diamond necklace is exactly the same as a necklace fitted with mined diamonds. It’s just less expensive and better for the planet.

Did you know that lab-grown diamonds can be as much as 60-80% LESS expensive than a natural diamond with precisely the same size, cut, and clarity measurements? The price difference allows you to buy a much bigger, better necklace.

The lab-grown diamond industry has developed with astonishing speed over the past few years. Last year, sales of lab-grown diamonds grew much faster than those of natural diamonds. Industry analysts quote a 63% increase in sales of manufactured diamonds in March 2022, compared with a 25% decline in natural diamond sales for the same period. The numbers will be even more staggering in the future.

What’s the reason for this massive growth in sales? Lab-grown diamonds are EXACTLY the same as natural diamonds in terms of chemical composition. They are graded by third-party industry organizations such as the Gemological Institute of America (GIA) in the SAME way as natural diamonds. What they offer is a way to purchase and own a stunning diamond necklace for far less than a natural diamond one – with significantly less environmental impact and no worker abuse.

Why you should buy a lab-grown diamond necklace

Lab-grown diamond necklaces are a timeless symbol of love and commitment, making them an ideal gift for special occasions. But there are many other benefits to buying a diamond necklace that make it an attractive purchase.

  • Beauty: No other gemstone sparkles like a perfectly cut diamond, and no other gemstone displays the same beauty as a ravishing diamond set in a gorgeous piece of jewelry. Diamonds have been coveted for centuries for their beauty and will make any type of jewelry stand out.
  • Selection and uniqueness: There is no shortage of styles for lab-grown diamond necklaces, ranging from classic solitaire designs to modern pendant pieces. Depending on your preference, you can also choose from different metal types, such as gold, silver, platinum, or rose gold. This makes lab-grown diamond necklaces a versatile and stylish choice for any occasion.
  • Durability and longevity: Diamonds are forever and are one of the hardest materials on earth, making them incredibly durable and long-lasting. They can withstand everyday wear and tear without losing their sparkle or brilliance, so you can be sure your lab-grown diamond necklace will last for years.
  • Affordability: Lab-grown diamond necklaces are much more affordable than the exact same mined diamond necklace with the same cut, clarity, color, and carat weight. But at a fourth or fifth of the price. This makes lab diamond necklaces affordable for most people, unlike many mined diamond necklaces that only the very wealthy can afford.
  • Avoiding negative impact: Lab-grown diamonds are not only a cheaper option than mined diamonds but also better for the environment and do not carry the negative human impact linked to the mining of diamonds.

Types of lab-grown diamond necklaces

There are many types of diamond necklaces, and thus also lab-created diamond necklaces, since, as we have just learned, they are the same. Lab-grown diamond necklaces come in a variety of styles and designs, each with its own unique characteristics. From classic solitaire pendants to more intricate pieces, there is something for everyone. Below are the most popular lab-grown diamond necklace types.

Read our guide to the best lab-grown diamond necklace ideas and get inspired!

Pendant Necklaces

Pendant necklaces are the most popular type of lab-grown diamond necklaces. They feature a single pendant, as a solitaire diamond or in the shape of a heart or other design, suspended from a chain. The pendants can be made from various materials such as gold, silver, and platinum and may contain lab diamonds and other types of gemstones. These necklaces offer versatility and can be dressed up for formal occasions or worn casually with jeans and a t-shirt.

Solitaire Necklaces

Solitaire necklaces feature one large diamond set into the center of an elegant metal setting such as gold or platinum. These pieces make great statement pieces that will draw attention to any outfit they’re paired with. Additionally, solitaire necklaces come in many different styles, so you can find one that perfectly suits your taste and style preferences.

A solitaire pendant necklace features a single diamond suspended from a chain or cord. This type of necklace is timeless and elegant, perfect for any occasion. The size and shape of the stone can vary depending on your preference; round-cut diamond shapes are often used for this style.

Multi-Stone Necklace

Multi-stone necklaces feature multiple lab diamonds set into one piece. These pieces can be arranged in various patterns, such as clustered or cascading stones, creating an eye-catching look that adds sparkle to any outfit. You can also choose different shapes and sizes to create a truly unique design that reflects your personal style.

Choker Necklace

Choker necklaces are short chains featuring several small diamonds arranged around the collarbone area of the wearer’s body. These types of diamond jewelry pieces look great when paired with dresses or blouses for special occasions but also work well when layered with longer chains for everyday wear.

Chokers come in many different designs ranging from classic to modern, so there is something available to suit every preference. Chokers are slightly longer than collars (up to 18 inches / 40 cm) but do not fit as tightly around the neck.

Collar Necklace

A collar necklace is a type of lab-grown diamond jewelry that fits tightly around the neck and has a rather big width. The length of this necklace does not exceed 13-14 inches (35 cm), making it ideal for evening dresses and emphasizing the beauty of open shoulders and neckline. However, if you have a short neck, this style may make it appear shorter.

Princess Necklace

Princess necklaces feature lab-created diamonds in the middle and can be up to 20 inches (50 cm) long – perfect for any jumper, top, or blouse! This piece of jewelry will emphasize your collarbone’s beauty while adding some extra length to your neck at the same time.

Matinee Necklace

Matinee-style diamond necklaces usually range from 20 inches (50 cm) up to 24 inches (60 cm). This type is excellent for casual wear since its length allows it to be worn over turtlenecks or sweaters without looking bulky or out of place. It also looks great when paired with v-neck tops or dresses.

Station Necklace

Station necklaces feature several small diamonds linked together by metal bars or links along the length of the chain or cord. This type of necklace gives off an effortless yet glamorous vibe that’s perfect for everyday wear or special occasions alike.

Tennis Necklace

Tennis necklaces are composed entirely of small diamonds strung together along a delicate chain link setting placed next to each other. These beautiful pieces add subtle elegance to any ensemble while still making quite the statement when worn alone as well! Due to the number of diamonds needed, they tend to be expensive, but much less so when set with lab diamonds.

Bar and Chain Link Necklace

Bar and Chain Link necklaces combine two different elements – bar settings with interlocking chains – which create an interesting texture when viewed up close but appear seamless. This type looks great, especially layered with other jewelry items like bracelets and earrings, for an added dimensionality to your look.

Overall, all lab-created diamond necklace types make great accessories, but which one you choose depends entirely on personal preference and budget constraints since each type has its unique characteristics that set it apart from the others.

What to know when buying a lab-grown diamond necklace

When shopping for the perfect lab-grown diamond necklace, there are several considerations to keep in mind. Below, we list the most important things to know when buying a lab-created diamond necklace so you can find the perfect one for you.

Lab diamond size and shape

The most crucial factor is the size and shape of the diamond. If you’re looking for something more subtle, then go for smaller diamonds with simple settings, whereas if you want something bolder, then larger diamonds with intricate settings will do the trick.

If you are shopping for a solitaire or pendant, we recommend a larger diamond and a brilliant-cut shape such as a round, pear, or heart-shaped lab diamond. These shapes sparkle and shine like no other and are perfect for being the center of attention with their commanding beauty. Aim for at least a 1-carat lab diamond.

However, smaller diamonds are preferred if the necklace is set with several diamonds or in an intricate and detailed setting. Often, these may be 0.5 carats or even smaller. e.g., in a diamond tennis necklace.

More elaborate settings fit well with subtle but larger diamond shapes such as Asscher or emerald.

Lab diamond quality

The quality of your chosen lab-grown diamond necklace will determine its price tag and how long it lasts over time.

Quality factors include the diamond 4Cs, such as clarity grade (the absence of inclusions or blemishes), color grade (how close it is to being colorless), and cut grade (the symmetry of the facets) should all be taken into account when shopping for a quality lab-grown diamond necklace.

Look for necklaces with lab-grown diamonds graded and certified by one of the leading diamond institutes, such as IGI or GIA.

The diamond certification provides assurance that each stone has been carefully examined and graded according to industry standards, so you know exactly what you’re getting when purchasing your necklace.

Additionally, check if any additional treatments have been applied to enhance color, the presence of fluorescence, and perfect polish and symmetry. Check the diamond certificates to make sure the grades are as advertised.

Types of lab-grown diamond necklaces

There are many different types of lab-grown diamond necklaces available on the market today. Popular styles include pendant and solitaire, station, multi-stone, and the impressive tennis with its many diamonds.

See the complete list of all necklace types above and find the perfect one for you.

Setting Considerations

The setting type used in your chosen lab-grown diamond necklace also plays a vital role in determining its overall look and feel.

Prong settings are popular due to their ability to show off maximum sparkle while still being secure enough not to worry about losing stones over time—just remember that prongs require more frequent cleaning. Other options, like bezel settings that encase each stone completely within metal walls, add protection against dirt buildup or accidental damage during wear.

Other settings include pavé settings in which small diamonds are placed close together along a band for an extra shimmering effect, channel settings where multiple gems sit side by side within grooves carved into metal frames, and halo designs featuring a larger center stone surrounded by smaller accent gems all around them creating an eye-catching effect.

Metal type

The metal type of a lab-grown diamond necklace can significantly impact its overall look and feel. Popular metals used for lab-grown diamond necklaces include yellow gold, white gold, rose gold, platinum, sterling silver, and titanium.

Yellow metal colors, such as gold, will impact the perceived diamond color. It’s therefore recommended to downgrade on diamond color since it’ll get a yellow hue from the metal anyway—and you can save a lot by choosing a lower color grade such as J or K.

In Summary: When shopping for a lab-grown diamond necklace, consider the setting and metal type that best suits your style, as well as quality factors such as clarity grade, color grade, cut grade, and whether to purchase lab-grown diamonds.

How to save on a lab-grown diamond necklace

If you’re looking for ways to save money on your new lab-grown diamond necklace without sacrificing quality, then there are a few strategies worth considering before making a final purchase decision.

  1. First off, shop for diamonds online instead of at traditional brick-and-mortar stores since most websites offer lower prices, a much larger selection, diamond inventory, and the ability to compare and inspect lab diamonds. The best places for lab diamonds provide free shipping and return so you can shop risk-free. See where to buy lab-created diamond necklaces in the next section.
  2. Look for discounts and promotions. Shopping around for the best prices on lab-grown diamonds is one of the most cost-effective ways to purchase a lab-grown diamond necklace. Shopping around online allows you to compare prices and find the best deal for your budget. We look for and list the best diamond discounts and sales so that you can save time and money.
  3. Opt for slightly lower grade diamonds, such as VS2 diamond clarity, rather than VVS1, or a lower diamond color grade, such as I or J. These differences won’t be noticeable unless viewed under magnification but could result in significant savings depending on cut-grade and carat weight.
  4. Finally, buy a lab-grown diamond. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds but are much less expensive than their mined counterparts. Our diamond price comparison documents that you can save 60-80% over a mined diamond! Just make sure they come certified by a reputable institute such as IGI or GIA, just like any other diamond should.

Caring for Your Lab-grown Diamond Necklace

Caring for your lab-grown diamond necklace is essential to ensure its longevity and sparkle. Proper cleaning and storage of your lab-grown diamond necklace can help protect it from damage, dirt, and dust. Here are some tips on how to properly care for your lab-grown diamond necklace:

Cleaning and Storing Your lab-grown Diamond Necklace Properly

It’s important to clean your lab-grown diamond necklace regularly to keep it looking beautiful. To do this, use a soft cloth or brush with warm soapy water. Avoid using harsh chemicals as they may damage the metal setting or gemstones of the necklace. After cleaning, dry off any excess moisture with a lint-free cloth before storing away in an airtight container or jewelry box lined with velvet or other soft material.

Insurance and warranty

Insurance coverage for your lab-grown diamond necklace is also recommended, as it will provide financial protection should anything happen to the piece, such as theft, loss, or accidental damage.

Before investing in additional coverage options, such as jewelry insurance plans offering more comprehensive protection at an affordable cost, check if you already have coverage through existing homeowner’s insurance policies. It may also be that the manufacturer or jeweler offers extended warranties that may cover some damages.

Lab-grown diamond necklace FAQs

How do you pick a lab-grown diamond necklace?
Firstly, determine your budget and the size of the lab-grown diamond you want. Next, consider what type of metal setting would best suit your style. Additionally, research different cuts and shapes that will flatter your face shape. Finally, check for quality certifications from reputable organizations such as GIA or IGI when buying a lab-grown diamond necklace to be confident in its authenticity and value.
How much should you pay for a lab-grown diamond necklace?
The cost of a lab-grown diamond necklace will depend on the size, quality, and type of diamond used. Generally speaking, lab-grown diamonds are less expensive than mined diamonds due to their lower production costs. As such, you can expect to pay anywhere from $500 for a small pendant with a single lab-grown diamond to several thousand dollars for larger pieces with multiple stones or intricate settings. Ultimately, shopping around and comparing prices is important to find the best deal that meets your budget and style preferences.
What size should a lab-grown diamond necklace be?
The size of a lab-grown diamond necklace depends on the individual’s preference and style. Generally, a smaller pendant or solitaire is best for an everyday look. However, larger diamonds can be chosen for more formal occasions to make a statement. The size of the chain should also be taken into consideration when selecting a necklace; it should complement the size of the diamond without overpowering it. Ultimately, choosing the right size diamond necklace comes down to personal taste and budget.
Is it OK to wear a lab-grown diamond necklace every day?
Yes, it is perfectly acceptable to wear a lab-grown diamond necklace every day. Diamonds are incredibly durable and can withstand everyday wear and tear without losing their beauty or sparkle. As long as the necklace is cared for properly by cleaning it regularly with a soft cloth, there should be no issue wearing it daily. Additionally, lab-grown diamonds are much cheaper than mined diamonds, and you can therefore worry less about having your necklace stolen or damaged.
What are the Differences Between a Pendant and a Necklace?
A pendant is a small piece of jewelry, such as a round diamond mounted in a prong solitaire setting, that can be attached to a chain and worn on different parts of your body like an anklet, necklace, or bracelet. A necklace is generally made up of a precious metal jewelry chain and can consist of gemstones linked together or be plain without any stones, and it’s always worn around the neck. Thus, a pendant can be a necklace, but it can also be a bracelet or another type of jewelry, while a necklace can be a pendant but also multi-stone, station, or something else.
