{"product_id":"sapphire-round-star-fantasy-cut-1-73ct","title":"Sapphire - Round Star Fantasy Cut  - 1.73ct","description":"\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eSapphire 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.\u003c\/p\u003e\n\u003cp\u003eEvery ring is made by Heather and her team in Boulder, Colorado, in platinum or 10k, 14k, or 18k gold.
