Why Buy Non-Certified Lab-Grown Diamonds
Lower Cost & Greater Efficiency: A grading report adds cost and lead time to every stone. On smaller stones, that cost can be a significant share of the stone's own value.
Ideal for Side & Accent Stones: Side stones, melee parcels, and pavé runs don't need individual grading reports, so certifying them adds unrecoverable costs.
Fast Stock Turnover: Non-certified stock bypasses lab certification delays, keeping inventory ready to use immediately.
The Same Premium Material: Non-certified describes the paperwork, not the material. Every stone is grown by CVD or HPHT to identical standards.
In-House Quality Screening: All stock is screened for cut consistency, colour evenness, and clarity before entering inventory.
Parcel-Matched in Antwerp: Matched to ensure a run of side stones stays consistent in colour and size across finished pieces.

Frequently Asked Questions
What are non-certified lab-grown diamonds?
Lab-grown diamonds supplied without an individual grading report. They're the same material as certified stones, grown by CVD or HPHT, screened in-house for consistency, and priced lower because there's no per-stone certificate. Typical uses are side stones, melee, halos, and pavé work.
Are non-certified lab-grown diamonds lower quality?
No. They're 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. 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 on its own grading specification. Order certified for a centre stone sold on its grade, or any stone sold at a distance.
What's the minimum order, and how fast is dispatch?
€500 minimum, with shapes and grades mixed to reach it. In-stock products dispatch within 1 business day, delivery in 1 to 3 days.
Do you supply lab-grown gemstones too?
Yes. Lab-grown sapphires and other materials are available.
