{"product_id":"sapphire-marquis-star-fantasy-cut-1-90ct","title":"Sapphire - Marquis Star Fantasy Cut - 1.90ct","description":"\u003cp\u003eThis 1.90 carat marquis sapphire is a natural parti sapphire from Montana, priced at $4,000. A parti sapphire carries more than one color in a single stone, and this one moves between teal, blue, and yellow. Brett Kosnar cut it as a star fantasy cut right here in Colorado, using concave precision faceting that gives the stone even brightness that holds from many angles as your hand moves. It measures 10.90 by 5.40mm.\u003c\/p\u003e\n\u003cp\u003eBecause it is mined in Montana, this sapphire is US-mined and traceable, with any heat treatment always disclosed. The star fantasy cut is shaped shallow, so it shows a larger face per carat and can sit lower and more securely in a setting than a standard-cut stone. Sapphire sits at 9 on the Mohs scale, plenty of hardness for everyday wear on a ring you will not take off.\u003c\/p\u003e\n\u003cp\u003eBohemi does not sell loose stones on their own. Each gemstone is set into an engagement ring or a custom project designed with you, built by Heather and her team in Boulder, Colorado. This marquis pairs naturally with the Arcadia small setting, or with a design of your own.
