FAQ About Wholesale Round Brilliant Cut Lab Grown Diamonds
Do you offer Ideal and 3EX cut grades for wholesale round lab diamonds?
Yes, over 95% of our bulk round lab-grown diamonds feature a Triple Excellent (3EX) rating for cut, polish, and symmetry, with many meeting Hearts & Arrows (H&A) or Ideal cut standards for maximum optical fire.
What is the minimum order quantity (MOQ) for certified wholesale round stones?
For stones 0.30ct and above, you can purchase single certified loose pieces based on your production needs.
Can you supply perfectly matched round pairs for diamond stud earrings?
Absolutely. Our advanced inventory sorting allows us to match pairs with identical millimeter dimensions, color shades, and clarity levels to guarantee uniform brilliance for wholesale buyers.
Are your round diamonds grown via HPHT or CVD technology?
We utilize both methods to optimize our stock. Typically, our smaller round melee stones (under 0.50ct) are grown via HPHT to achieve high color grades naturally, while our larger rounds leverage advanced CVD technology.
Do you supply uncertified round loose diamonds in commercial parcels?

Can I request specific millimeter tolerances for automated jewelry casting?
Yes, we accept custom orders with strict tolerances down to +/- 0.05mm for high-volume automated setting lines. Please submit your technical requirements via our inquiry form.
