Wholesale, Natural & Lab-Grown
Wholesale Round Diamonds
Natural and lab-grown are two separate lines here, never mixed on one certificate or one price list.
Round brilliants are the reference point for the whole trade. Fifty-seven or fifty-eight facets, a cut grade printed on the report, and a price every dealer in the market can check against a benchmark. When a client wants a stone they can comparison shop, this is the shape they end up in.
Wholesale buyers work in round for one reason above all others: it moves. A well-cut round sets into anything, sells in every store, and holds its value better than any fancy shape. Studs, tennis lines, halos, three-stone work, and the plain solitaire that still outsells everything else all start here.
Round is the deepest shelf we carry. Over 800 natural rounds and over 4,900 lab-grown rounds are available today, spread across every carat band we sell. More than 1,400 of the lab rounds are three carats and up. On the natural side, 71 stones sit right around the one carat mark, which is the band most retail jewelers restock fastest.
Buying Round Diamonds Wholesale
Round is the only shape that carries a real cut grade, so start there and then keep going. Two stones both graded Excellent can behave differently in the hand. Read table and depth together, look at crown angle when the report gives it, and watch the video with the stone in motion. Light return either holds up when the stone moves or it does not.
On natural goods, fluorescence is where the money hides. Strong blue in a D to F stone still trades at a discount that owes more to old trade habit than to how the stone actually faces up. If it looks white and clean on video, that discount is yours to take. In the lower colors, faint to medium blue often helps the stone rather than hurting it.
Lab-grown rounds mostly arrive with IGI Excellent cut, so the grade stops separating one stone from the next and the spread does that work instead. Compare color and clarity against price per carat, and be realistic about what a setting will cover. Nearly all of our natural stock is GIA graded and nearly all of the lab stock is IGI graded, so judge each line against its own benchmark.
For studs, ask about matched pairs before you buy two singles. Every pair we hold today is lab-grown. Buying a pair costs less than assembling one yourself once you count the hours spent matching color, clarity, and millimeter across two separate parcels.
Frequently Asked Questions
What do wholesale round diamonds cost?
Natural rounds trade in the thousands of dollars per carat and lab-grown rounds trade in the hundreds, which is the single biggest reason the two lines are quoted separately. Within each line the price turns on carat band, color, clarity, and cut quality. Sign in to your trade account and the price shows on every stone in the list.
Do you keep natural and lab-grown rounds separate?
Yes. Natural and lab-grown are two separate lines here, with separate stock, separate pricing, and separate sections of the inventory. Nothing is mixed into a blended search result, so a natural round is never quoted next to a lab round without you asking for it.
What sizes of round diamond do you stock?
The round shelf runs from under half a carat up through the large sizes, with over 1,400 lab-grown rounds at three carats and up. The one carat band is well covered on both lines. If you need a specific millimeter rather than a specific weight, call and we will pull to measurement.
Is the cut grade on a lab-grown round the same as on a natural?
The grading scale is the same, but the labs behind it usually are not. Natural rounds here are almost all GIA and lab rounds are almost all IGI, and the two labs are not always identical in how they land a borderline stone. Compare within a lab, not across them.
