This is a 1-carat ruby-colored moissanite, precision cut in a Russian-style brilliant. Often referred to as a “Russian cut,” this facet pattern is a refined variation of the modern brilliant, designed to emphasize symmetry, contrast, and controlled fire rather than chaotic sparkle.

Moissanite has become a standard material in modern jewelry for good reason. It offers excellent hardness, durability, and optical performance, making it suitable for daily-wear rings, pendants, and heirloom-style pieces. This stone cuts cleanly, sets predictably, and performs well in both minimalist and pavé-supported designs.

This listing is for the loose gemstone shown. If you’re looking to have jewelry made and want to select the stone first, this piece is also available as the starting point for a custom ring or pendant.
