Our New World Diamonds review verdict
New World Diamonds is most interesting if you want a colored lab-grown diamond. Its selection goes beyond the white stones that dominate most jewelry websites, making it worth a look for a pink, blue or yellow diamond and more unusual colors.
Our rating remains 3.6/5. We like the choice of colors and the value we found in our dated searches. We are less enthusiastic about some preset jewelry details and the flexibility of the return policy. For a conventional white-diamond engagement ring, we would start with our leading jewelers instead.
If price is your priority, compare loose diamonds at Ritani. If you want a finished design, our Grown Brilliance review is another useful starting point.
Who are New World Diamonds?
Our review traced New World Diamonds to 2018. The company set out to make lab-grown diamonds more accessible, with colored stones an important part of the range.
Its current website offers loose diamonds, engagement rings, earrings, necklaces and other finished jewelry. The wide choice makes it more useful for someone with a particular color or piece in mind than for a buyer who wants the smallest possible shortlist.
New World Diamonds is a real jewelry business, and our research found a workable online buying process. We would judge the specific diamond, report and order terms before choosing it over our preferred sellers.
Our review also discussed its presence on large marketplaces. Selling through Amazon or another marketplace is not, by itself, a reason to distrust a jeweler. The important questions are who supplies your order, which diamond you receive and what protection applies to that purchase.
A specialist in lab-grown diamonds
New World Diamonds focuses on lab-grown rather than mined diamonds. A lab-grown diamond is a real diamond; it is not a simulant such as cubic zirconia. Its origin does not tell you how well it is cut or how attractive an individual stone will be.
We like being able to put more of the budget toward a design or diamond size we enjoy. But we would not choose a stone based on a broad promise about sustainability or value alone. Ask about the actual diamond and compare the finished price.
For colorless stones, cut has a large effect on sparkle. For colored diamonds, the color itself becomes a central part of the decision: its hue, strength and how evenly it appears across the stone.
New World Diamonds' selection
The range is the strongest reason to consider this seller. It offers the familiar white lab-grown option alongside colors that can make a ring feel very different. You can buy a loose diamond or look for a piece that has already been put together.
Fancy-colored diamonds
Our inventory review found 735 colored lab-grown diamonds, with about 83% carrying IGI reports. Those are historical search counts, but they show why colored stones became the focus of our recommendation.
The current website still gives colored diamonds considerable space. Its categories include pink, blue, yellow, green, orange and other shades. That is a welcome alternative if a colorless solitaire does not appeal to you.
When choosing a colored diamond, start with the shade you actually like. A more intense color is not automatically more beautiful to its wearer. Compare photographs or video in neutral lighting, and ask whether the images show the stone you would receive.
The metal and setting can change the overall impression too. A yellow-gold setting may suit a warm yellow stone, while a white metal creates a different contrast. If you are designing a ring, look at the proposed combination rather than choosing the diamond and setting in isolation.
White lab-grown diamonds
New World Diamonds also sells white diamonds. In our review, the white-diamond inventory was smaller than at the largest sellers we compared. That left fewer alternatives when we narrowed the search to our preferred specifications.
For our round-diamond reference search, we looked around one carat, generally I–J color and VS2 clarity, and prioritized the highest available round cut category. The idea was to find an attractive diamond without paying for grades that might make little visible difference.
Those are comparison criteria, not a rule for every buyer. Some people prefer a colorless grade, and a warmer stone can suit yellow gold. With an elongated shape, measurements and appearance may be more useful than hitting an exact carat figure.
For a standard white-diamond purchase, we prefer a broader shortlist and easier side-by-side inspection. That is why New World Diamonds sits below our main recommendations even though some individual stones can be good buys.
Buying and inspecting a diamond
Our shopping research found a reasonably straightforward journey from search results to diamond details. We could examine photographs, open grading information and view diamond videos. We liked having those tools available rather than relying only on a brief product description.
There is an important detail in the current return policy: product images and videos may be representative rather than the actual diamond. Ask for confirmation and footage of your chosen stone before ordering, particularly when its color is the reason you want it.
Reports and preset jewelry
The current FAQ says that grading laboratories vary and that some requested stones are sold without reports. For finished jewelry, certification should be stated in the listing. Read the report for your selection rather than assuming every piece comes with the same documentation.
in our review, some preset earrings had less detail about cut than we wanted. We would prefer to know more before paying for larger diamond studs: whether the stones match, what their grades mean in practice and how lively they look together.
IGI and IGL are different organizations. Similar initials do not mean the report is from the same laboratory. For an individually chosen loose stone, a clear independent report and useful images make comparison much easier.
This does not mean every small jewelry diamond needs its own report. The larger the diamond and the more it contributes to the price, the more important that individual information becomes.
Are New World Diamonds' prices good?
We found competitive prices in our review. Our roughly one-carat reference search produced options from just under $1,000 to about $1,200. Those prices belong to the dated research period, not the current market.
Lab-grown diamond prices have changed considerably since then. Use our current one-carat price guide to get a better sense of what comparable white stones cost now.
For colored diamonds, compare stones with a similar color and appearance. A low price for a pale or uneven-looking stone is not necessarily better value than a more appealing diamond that costs more. The same applies to shape: a stone you enjoy wearing is more important than the lowest price per carat.
With finished jewelry, include the setting, chain or matching pair in the comparison. A large advertised discount tells you little without a sensible starting price. We would ask for the complete cost and compare it with another piece we would genuinely consider buying.
Shipping and returns
New World Diamonds' shipping FAQ lists free standard US shipping above $100 and free express shipping above $2,000. Shipments are insured. In-stock items generally leave within two to three business days; custom work takes longer.
The returns page, checked in September 2026, offers 30-day returns for most eligible US orders over $100. Items must be unworn, tagged and accompanied by their documents. Modified, resized, exchanged and upgraded pieces are excluded.
If you have previously returned an order for a refund or canceled during production, the next purchase qualifies for store credit rather than another refund. Credit purchases are final sale. International orders do not receive free returns. Custom jewelry may have a restocking fee or be final sale; agree the terms before paying.
That makes New World Diamonds less suitable for buying several options to compare at home. Decide whether you are comfortable with the specific piece before ordering, rather than treating every purchase as a risk-free trial.
Our final recommendation
We would consider New World Diamonds for a colored lab-grown stone that is difficult to find elsewhere at an appealing price. The range is its strongest advantage, and we like the opportunity to build jewelry around a color you love.
For a white-diamond engagement ring or straightforward studs, we would compare our recommended jewelers first. They generally offer a stronger combination of diamond choice, shopping tools and buying confidence.
Our 3.6/5 assessment reflects that balance. New World Diamonds can be the right seller for a particular stone, without being our first recommendation for every kind of jewelry.
Customer feedback
We included customer feedback in our review to see how the buying experience compared with our website research. The screenshot below is part of that earlier work, not today's review total.
Look for recent accounts about the kind of purchase you are considering. For a custom colored ring, communication and the finished appearance are especially helpful topics. For a ready-made gift, delivery and handling of returns may matter more.
