Non-Certified Lab-Grown Diamonds
Quick answer: LabGems supplies non-certified lab-grown diamonds at a lower price than certified stock, ready to ship from Antwerp. They are the same material as certified stones, grown by CVD or HPHT and screened for consistency, supplied without an individual grading report. They suit melee, side stones, halos, and pavé, where the stone is set into a finished piece rather than sold individually on its grading specification. Minimum order €500, in-stock products dispatched within 1 business day.

Why buy non-certified
A grading report adds cost and lead time to every stone. On smaller stones, that certificate can be a significant share of the stone's own value. For how certification cost fits into a wider sourcing budget, see the wholesale buying guide for retailers.
Side stones, melee parcels, and pavé runs do not require individual grading reports. Certifying a side stone or accent stone adds a cost that cannot be recovered in the retail price, and it delays stock that needs to be available for immediate use.
What you receive
Non-certified describes the paperwork, not the material.
Every LabGems non-certified lab-diamond is the same material as a certified one, grown by CVD or HPHT. All non-certified stock is screened for cut consistency, colour evenness, and clarity before it enters inventory.
Stones are parcel-matched in Antwerp, so a run of side stones is consistent in colour and size across a finished piece.
IGI certification is available on request when an independent grade is needed. For more trade guidance on certification and sourcing, see the LabGems lab-grown blog.
How quality is assured
Without a per-stone certificate, the supplier's screening process carries more weight than it does with certified goods.
All non-certified stock is screened and parcel-matched in Antwerp before dispatch. Both CVD and HPHT material is held, and certified and non-certified inventory is managed under the same quality controls. Account access is trade-only and verified. Stock ships from the Antwerp Diamond District, keeping delivery times short across Europe.

Frequently asked questions
What are non-certified lab-grown diamonds?
Laboratory-grown diamonds supplied without an individual grading report. They are the same material as certified lab-diamonds, grown by CVD or HPHT, screened in-house for consistency, and priced lower because there is no per-stone certificate. The typical applications are side stones, melee, halos, and pavé work.
Are non-certified lab-grown diamonds lower quality?
No. They are the same material as certified stones, screened for cut, colour, and clarity consistency before entering inventory. The only difference is the absence of an individual certificate.
How is quality assured without a certificate?
All non-certified stock is screened and parcel-matched in Antwerp before dispatch. Account access is trade-only and verified. IGI certification is available on request when an independent grade is needed.
When should I order non-certified instead of certified?
Order non-certified for side stones, melee, halos, and pavé, where the stone is set into a finished piece rather than sold individually on its grading specification. Order certified for a centre stone sold on its grade, or for any stone sold at distance where the buyer cannot inspect it.
What is the minimum order, and how long does dispatch take?
Minimum order €500, with shapes and grades mixed to reach it. In-stock products dispatch within 1 business day, delivery 1 to 3 days. Net-30 and Net-60 for approved accounts.
