Irresistible, extraordinary duo of beauty and rarity in one of a kind handmade creature: gorgeous ring with a magnificent 13.15 carats, color changing sapphire, an exceptionally rare, fancy variety of corundum which exhibits the unique ability to change color. The unique and rare ability to color change occurs only in rare sapphire that forms with two light transmission windows rather than one. Approximately only 7% of all sapphires change color . This 13.15 carats color change sapphire exhibits excellent transparency and superb luster, which is quite rare for sapphires and makes this gemstone really unique especially that it was spared exposure to treatment and its clarity and color are thus entirely natural. Assented by two white trapezoid diamonds this beautiful gem is set in white and yellow gold handmade setting.
