A 1-carat lab grown diamond costs roughly $191 at wholesale. Retailers charge $800 to $1,200 for the same stone. CaratVault closes that gap with pricing you can actually verify.
The International Gemological Institute is the gold standard for lab grown diamond grading. Every stone on CaratVault comes with a full IGI report documenting origin, cut, color, clarity, and carat weight.
