Customer Reviews
"I was nervous buying a diamond online, but KLARÈVE made it completely seamless. They emailed me the IGI report before shipping and the stone was exactly as described. My jeweler was genuinely impressed."
THE CLASSIC
"The Signature collection was exactly what I was looking for. Genuinely colorless to the eye — I compared it side by side with my friend's mined diamond and couldn't tell the difference. Incredible value."
THE SIGNATURE
"The Reserve is exactly what it promises. The IGI report confirmed D/VVS1. I brought it to two jewelers before setting and both said it was one of the finest stones they'd seen. Worth every penny."
THE RESERVE
"Transparent pricing, no pressure, and the IGI report emailed before shipping gave me total confidence. The stone was exactly as described and KLARÈVE handled everything seamlessly."
THE CLASSIC
"I got an E/VS1 — the IGI report arrived within 24 hours so I could verify the grade before it shipped. The whole process from order to delivery was 6 days. Stunning stone and the IGI report is a great keepsake."
THE SIGNATURE
"Bought for an engagement ring. My partner had no idea it was lab-grown until I told her — she was amazed. The loose diamond arrived beautifully packaged with the IGI report. Highly recommend."

Frequently Asked Questions
Everything you need to know about your KLARÈVE diamond.
Yes. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. They are composed of pure carbon in a cubic crystal structure — the same as natural diamonds. The FTC, IGI, and GIA all recognize lab-grown diamonds as real diamonds.
Every KLARÈVE diamond ships with an IGI grading report that includes: carat weight, color grade, clarity grade, cut grade, polish, symmetry, fluorescence, a proportions diagram, and a unique report number you can verify at igi.org.

The price includes the IGI certification, free insured shipping, and 30-day returns. You never pay per-carat or negotiate — the listed price is the final price.
