Wholesale Cushion Lab-Grown Diamonds
Frequently Asked Questions (FAQs)
LabGems non-certified cushion lab-grown diamonds span four commercially distinct combinations: modified brilliant or standard faceting, in square or elongated rectangular profiles. Modified brilliant suits contemporary engagement where scintillation drives sales; standard faceting suits heritage retail. This is the broadest configuration choice across the non-certified inventory, at approximately 20% below certified cushion pricing.
For single-ratio cushion inventory, a 1.10 to 1.20 length-to-width ratio captures the broadest retail demand: slightly elongated, finger-flattering, and recognisably cushion. Trade buyers wanting dedicated square stock with 1.00 to 1.05 ratios should review the certified square cushion collection. LabGems holds non-certified cushions from approximately 0.30ct through 5.00ct.
Cushion is one of the strongest shapes for fancy colour because deliberate depth retention maximises saturation. LabGems carries coloured cushion stock separately within the coloured lab-grown diamonds range in pink, blue, green, and orange. The non-certified cushion collection here covers white stones graded in-house against the same 4Cs framework as certified inventory.
No. LabGems non-certified cushion lab-grown diamonds come from identical Antwerp supply partners as certified cushions; the only difference is the IGI certificate, not the stone. All stones are graded in-house by LabGems graders against the same 4Cs standards. The 20% saving reflects the removal of the IGI report cost only, the stone itself is identical.
