Vintage C de Cartier Diamond Ring

The Vintage C de Cartier Diamond Ring is a rare, discontinued piece of Cartier history. Set in 18K white gold with 0.20 carats of F-G color, VS clarity diamonds, it features the iconic double C design that has defined the Maison for generations.

It's a pre-owned estate piece in size 3 3/4, and only one is available.

The C de Cartier Design

The double C motif is one of Cartier's most recognizable signatures, a tribute to the brand's founding family. On this ring, the interlocking Cs are paired with brilliant diamonds for a design that feels both classic and modern. Because it's discontinued, it's no longer available new from Cartier.

The Diamonds: Top-Tier Color and Clarity

The ring's diamonds total 0.20 carats and are graded F-G color and VS clarity, both in the upper range of the diamond grading scales.

F-G Color

On the D-to-Z color scale, F falls in the colorless range and G sits at the very top of near-colorless. These diamonds look icy white, especially against white gold.

VS Clarity

VS stands for "very slightly included," one of the higher clarity grades. VS diamonds are eye-clean, meaning they look flawless to the naked eye. Any tiny natural characteristics can only be found by a trained grader under 10x magnification.
