The article explores our mission, our guaranteed grading, and how we are working to bring greater transparency and trust to diamond certification. It also takes a closer look at how 8X® cut grade standards were developed.

We’re excited to see The Floeting Diamond featured in the latest issue of Rapaport Magazine (pages 26–27), highlighting a new approach to diamond setting by The Village Goldsmith.

The Floeting Diamond features a patented design with a precision-engineered micro-groove that allows it to be securely set in a high-tensile specialist alloy, preserving full light return while removing the need for visible prongs or bezels.

Thank you to The Village Goldsmith for the kind mention of GCAL by Sarine. We’re proud to have certified the Floeting Diamond as Ideal Cut.

💎 You know the 4Cs—Carat, Color, Clarity, and Cut. But did you know a Cut grade is often left out of grading reports for fancy shapes like Hearts, Ovals, and Marquises?
Not with GCAL by Sarine. Our Signature Diamond Grading Certificates include Cut grades for fancy shapes, so you’ll know all 4Cs and if your diamond is truly well cut—because better cut means more brilliance and sparkle.
