Whiteflash would be on my shortlist for a round lab-grown diamond if cut were my first priority. Of the two Precision Lab rounds I looked at, my first choice was the $950, 1.05-carat D/VVS2. The $1,470 alternative was a D/Flawless and faced up almost the same size. Another $520 would need to buy me a visible difference.
I also priced a simple white-gold solitaire at $750. That put my starting ring budget at about $1,700 before tax using the two listed prices. I didn’t get a combined checkout quote, so confirm the total and delivery date before ordering.
Our bottom-line verdict
Whiteflash is the stronger fit when seeing how a round diamond handles light matters to your choice. The $950 Precision Lab sample is where I would start. At roughly $1,700 with the solitaire, compare the finished quote and give yourself time to inspect the ring within the return window.
Is Whiteflash legitimate?
Yes. Whiteflash sells diamonds and settings online and lists a showroom in Sugar Land, Texas. The IGI report I opened for the 1.05-carat round agreed with the grades and measurements shown on its listing. Check the report and the inspection deadline for your own order. Whiteflash FAQ
Whiteflash lab-grown diamond prices
Both were round Precision Lab diamonds with individual images, measurements and IGI reports listed. Here’s what the two loose stones cost in our November 7, 2026 US shopping check.
| Round Precision Lab diamond | Diameter | Listed price |
|---|---|---|
| 1.05 ct D / VVS2 | 6.50–6.54 mm | $950 |
| 1.03 ct D / Flawless | 6.50–6.53 mm | $1,470 |
The nearly identical diameters made this an easy place to start. I would rather spend some of that $520 difference on a setting I love than pay for Flawless clarity on paper. These were different diamonds, so the price gap doesn’t tell us what that clarity upgrade costs across Whiteflash’s inventory. Both pages also showed lower wire prices. Use the same payment method when you compare quotes. 1.05 ct sample · 1.03 ct sample
What the setting adds to the price
The Valoria six-prong solitaire in 14K white gold was listed at $750. With the $950 diamond, the two listed prices came to $1,700 before tax or extra work. Selecting the diamond opened the setting search, so ask Whiteflash to confirm the fit, total and completion date for the assembled ring. Valoria solitaire
To compare another jeweler’s price, start with a round of similar diameter and a similar solitaire. Then watch how the stones handle light. A cheaper diamond is worth considering if I like how it looks and can get enough information to order confidently. Our Ritani review · Our lab-grown diamond price guides
What I liked about shopping for the diamond
Both listings let me look beyond the color and clarity grades. I could see the dimensions and angles, open the stone-specific ASET, Ideal-Scope and hearts images, and check the report number. The linked IGI report for the 1.05-carat diamond agreed with the listing on the grades, measurements and proportions. It also identified the stone as HPHT-grown and recorded no indication of post-growth treatment. The listing with the IGI report
If you’ve never used those images, start with the video and see which diamond catches your eye. Then look at the ASET or Ideal-Scope images side by side. ASET helps show where the diamond gathers light and where you see contrast. Ideal-Scope helps you spot areas of light leakage. The hearts view is useful if you care about the evenness of the pattern in a round. Ask Whiteflash to explain any difference you see before paying more for one stone.

Precision Lab and supplier listings
Whiteflash says its Precision Lab diamonds are in stock and that other stones can be brought in from suppliers. Check the image tabs on the exact diamond before paying for the extra inspection detail. Our two examples were branded rounds. If you want an oval or a supplier-listed stone, ask which views you can see and whether you need to commit to the order to get them. Precision Lab collection · Whiteflash’s supplier inventory FAQ
When the extra cut information is worth paying for
If you are choosing between two similar rounds, watch their videos before reading the branding. Pay attention to what goes bright and dark as each stone turns. Then open the still images and see whether they help explain a difference you noticed. That’s where Whiteflash earns a place on my shortlist. There is something concrete to ask the seller about.
I would give the extra images less weight if I already liked another well-documented round and could not see an advantage in the Whiteflash sample. Get finished-ring prices for both. The extra information is worth paying for when it changes your choice or gives you enough confidence to order.
For the $950 round, the linked report and the listing were enough to keep the stone on my list. Setting height was still an open question. Ask for the profile dimensions if you wear gloves, catch rings on clothing, or want a wedding band to sit close beside it. Our engagement-ring buying guide
Returns and aftercare
The 10-day return period is the detail that matters most on eligible lab-grown orders. The clock can start when the parcel is available for pickup, so arrange any independent inspection before it arrives. Ask what fees would be deducted and what happens if you order custom work or have the ring altered. Whiteflash’s published lifetime trade-up program excludes lab-grown diamonds. Money-back terms · Trade-up policy
Would I buy from Whiteflash?
I would keep the $950 round on my list. I like being able to see the exact stone and check its report without having to buy it first. The next step is a finished-ring quote and a second round to compare it with. If the setting is the harder choice, try a few on in a showroom. Our Blue Nile review

How we reviewed Whiteflash
I compared the report and actual-stone images, what they helped me judge, the cost of a simple ring and the time available to inspect it after delivery. I used two branded round listings, opened the linked IGI report for one, and priced a catalog setting. The review covers how much you can learn before paying. A purchase and physical inspection would be needed to judge the finished ring, delivery and aftercare and rate those parts of the purchase. Our editorial review process
