Sapphires are a variety of corundum, the same mineral as rubies, and have a hardness second only to diamonds. The color of corundum varies depending on the impurities (metal ions) present. When about 1% chromium is mixed in, it becomes a deep red ruby. When iron and titanium are mixed in, it becomes a blue sapphire. Pink sapphires are those with only 0.1% chromium. Sapphires come in a variety of colors besides blue, such as pink, yellow, and green, due to impurities like chromium, nickel, and cobalt. These are called fancy color sapphires. This ring has a very attractive color, somewhere between red and orange. I've seen many stones, but I rarely see such a vivid red-orange. The design, with cubic zirconia surrounding the stone, is also very glamorous and complements the main sapphire stone beautifully ♡ Size: Stone size: Approx. 4.5 x 3.5mm Silver 925 Cubic Zirconia Myanmar origin
