{"product_id":"1-75-ct-cushion-cut-teal-sapphire-unheated","title":"1.75 ct Natural Unheated Teal Sapphire – Cushion Cut | GIA Certified | Madagascar","description":"\u003cp\u003eA natural 1.75 carat teal sapphire in a cushion cut, completely unheated, certified by GIA (Report #1246017790). Teal sapphire is natural corundum at the intersection of blue and green — a dual-tone color that shifts between its blue and green components depending on angle, distance, and light source. The cushion cut at 1.75 carats concentrates the teal saturation across a broad face, making the color-shift character visible and vivid in any setting. Teal sapphire is almost universally unheated — heat treatment typically collapses the blue-green balance into a single hue, and GIA's report confirms no indications of heating on this stone.\u003c\/p\u003e\n\u003cdiv style=\"border: 2px solid #5b2c6f;
