FAQ About Wholesale 3 Carat Lab Grown Diamonds
Do your 3-carat diamonds show a "blue nuance" or "brown tint"?
No. We employ slow, highly optimized growth parameters that eliminate phosphorescence (blue nuance) in HPHT and avoid the brown tints common in low-tier CVD diamonds.
Is a 3-carat Emerald cut diamond more likely to show inclusions than a Round cut?
Yes, step-cut shapes like Emerald and Asscher cuts have large open tables that offer a clear window into the stone. We suggest opting for VS1 or higher for 3ct step cuts.
Do your 2ct CVD diamonds show any brown undertones (brown tint)?
No. We reject any CVD rough that exhibits brown or grayish undertones. Our 2ct CVD stones are chemically pure, yielding crisp, white diamonds.
Do all your 3ct loose lab grown diamonds come certified by GIA?
We maintain a balanced stock of both IGI and GIA certificates. You can filter and request exclusively GIA-certified 3ct stones during the inquiry process.
What is the visual diameter of a standard 3-carat Round Brilliant diamond?
A standard ideal-cut 3ct Round Brilliant has a visual face-up diameter of approximately 9.3mm to 9.4mm.
What is the maximum clarity you can produce for a 3-carat diamond?
We regularly produce VVS1, VVS2, and internally flawless (IF) grade diamond crystals up to 3 carats.
Are your 3-carat lab diamonds conflict-free and eco-friendly?
Yes, our entire production relies on advanced laboratory environments powered by sustainable electricity, ensuring zero mining impact and 100% conflict-free tracking.
