Certified Gemstones

Proof You Can Trust. Quality You Can See. 

At Precious Carats, certification is not an add-on—it’s our foundation. Every gemstone in our collection is 100% certified by gem testing laboratories of global and national repute—credible, verifiable, and known for their integrity. 

We do not issue in-house certifications. Every certificate is issued by an independent third-party laboratory—labs known for their honest operations, scientific rigor, and global trust. All our certificates are verifiable on the respective websites of these labs.
