Tips
- Measure at the end of the day, when fingers are warmest.

Ring Details
Carat Weight
Minimum carat weight. You may receive a slightly higher carat weight.
Clarity
Clarity grades how clean the diamond is. Fewer tiny inclusions means higher clarity.
All our diamonds are 100% eye-clean.
Color
Color grades how white the diamond is. D is the whitest; Z has a faint yellow tint.
All our clear diamonds are F or higher, in the "colorless" range.
Cut
Cut is how well the diamond is faceted, not its shape. A great cut sends light back at you for that signature sparkle.
The top cut grade depends on shape: "Ideal" is the highest for round diamonds; "Excellent" is the highest for fancy shapes (oval, cushion, emerald, and so on).
Every Next Diamonds stone is graded the highest for its shape. Maximum brilliance, no compromise.
Shape
Shape is the outline of the diamond when viewed from above. Round, Oval, Cushion, Emerald, and so on.
Origin
All our diamonds are lab-grown, and they are real diamonds. Same hardness, same sparkle, same chemical structure as mined ones.
Created in a lab, not pulled from the earth: better for the planet, ethically sourced, and more accessible.
Certificate
Every diamond comes with an IGI certificate, the world's leading laboratory for lab grown diamonds. This independent report verifies the diamond's exact specifications and authenticity.
The certificate is included in the package.
Metal
14K gold is durable and the most popular for daily wear. 18K gold is purer and slightly softer with a richer color.
Platinum is the premium choice. Heavier, naturally white, and hypoallergenic.
