What you need to know before buying a lab-grown diamond
Before we start, let’s revisit some lab-grown diamond basics. These do not differ from the diamond basics since lab-created diamonds are exactly the same as mined (the process of getting them into your hands is just better).
If you shop at any of our recommended places to buy lab-grown diamonds online, you generally should not worry. You will be making a great deal, especially if you avail of their excellent service and guidance. However, it pays off to prepare yourself.
The first thing you need to know is the diamond 4Cs. These are diamond cut, diamond color, diamond clarity, and carat. They are the key characteristics that diamonds are evaluated by and what you should look for when shopping for a lab-created diamond. Let’s go through each of them.
Diamond Cut
The most important thing you need to know is that diamonds are all about brilliance, another word for how diamonds sparkle. This is what makes diamonds unique. Diamonds sparkle when they reflect light. The reason the light is so special is the complex way that diamonds are cut.
You can learn more in our in-depth article about lab-grown diamond cuts, but suffice it to say that the diamond cut is by far the most essential aspect when determining the quality of a diamond. Diamond cut is graded by independent institutes such as GIA and IGI, who provide diamond certificates.
What you should look for are diamonds with either excellent or ideal cut (some grading institutes uses “excellent” as the highest grade, and others like IGI use “ideal”). Always go for the highest grade. It’s that simple.
Diamond clarity
Clarity tells you if there are any inclusions or blemishes in the stone. Simplified, these are imperfections in the stone. However, most are so small that the naked eye cannot see them. The problem is when they are too large or placed in an adverse spot, impacting light reflection. The only way to tell is by studying high-quality images and videos. This is something the best diamond sellers offer, and you should only shop at jewelers where you can properly inspect the diamond (all our top 6 best places to buy lab-grown diamonds do that).
We recommend clarity grades from VS1 to S2. Do not go below S2; if in doubt, stay closer to the VS grades. Learn more about lab-grown diamond clarity in our detailed article.
Diamond color
The same is the case for diamond color. Diamond color is the absence of color. Colorless, sometimes referred to as white diamonds, should be just that. However, most diamonds have a slightly yellow or brownish tint. And that’s usually fine. Like the slight imperfections, you will not be able to see them as long as you pick a decent color grade. As the case was with diamond clarity, you want to avoid a tint so strong that it detracts from the sparkle and beauty of the diamond.
In most cases, it does not. But you want to make sure you can inspect the diamond thoroughly to avoid any surprises. Then, as the case was with the diamond clarity, study the images and videos (the best places to buy lab-grown diamonds all offer that).
Aim for a color grade between I and J. This is more than sufficient; you can save a lot by downgrading. Spend the saving on selecting a better diamond cut. If you set the stone in a golden setting, you can also consider going to K grades. Learn more in our guide to lab-grown diamond colors.
If you are considering a so-called fancy-colored diamond (ie., not colorless, but pink, blue, etc.), then learn more in our guide to fancy-colored lab-created diamonds.
Diamond carat
This is undoubtedly the best-known of the 4Cs. Many people mistake carat for size, but it’s a measure of weight. For example, 1 diamond carat equals 0.007 ounces or 0.2 grams. But carat sounds more impressive. When it comes to diamond carats, you need to know the following:
- Two diamonds carrying the same weight (carat) may appear very different. This is because you only see the surface of the diamond, much like an iceberg. However, having a large surface is not necessarily desirable. As mentioned, the light-emitting qualities are what matter, and these have to be just right. That requires an exact surface-to-depth ratio.
- This leads us to the second point. A lighter (“smaller”) diamond may appear much bigger than a larger one if the diamond cut is better. That is because the perceived size of a diamond depends more on the brilliance than the actual size. Which in turn depends on the quality of the cut.
In short, prioritize diamond cut over carat weight. First, choose an excellent or ideal cut, pick suitable ranges of clarity and color grades, and lastly, see what carats fall within your budget. This way, the carat weight is the only variable that should impact cost – all others you should not compromise on. Read more about lab-grown diamond carats in our detailed article.
