This 1.73 carat sapphire is a dark green-blue teal round, faceted in a star fantasy cut and priced at $2,900. The Kenyan sapphire measures 7.4mm across and was cut in Colorado by Brett Kosnar. A star fantasy cut uses concave precision faceting, so brightness holds evenly as the stone tilts, and because it is cut shallow it shows a larger face per carat than a standard round.

Sapphire is a 9 on the Mohs scale, hard enough for everyday wear on an engagement ring, and a fantasy cut like this can sit lower and more securely in a setting. Bohemi does not sell loose stones on their own: each center stone is set into an engagement ring or a custom project designed with you. This teal sapphire works beautifully in the Sagitta knife-edge solitaire, the Chrysos setting, or a fully custom piece.

Every ring is made by Heather and her team in Boulder, Colorado, in platinum or 10k, 14k, or 18k gold. Reach out to see more photos or to start a design, and browse the rest of our engagement rings.
