Description
- You will receive exactly this Red Ruby Rough Set of 10 pcs ! Set Weight: 1.7g / 0.06 oz / 8.5 Carat.
- Ruby is distinguished for its bright red color, being the most famed and fabled red gemstone. Beside for its bright color, it is a most desirable gem due to its hardness, durability, luster, and rarity. Transparent rubies of large sizes are even rarer than Diamonds.
- Ruby is the red variety of the mineral Corundum. Sapphire, the other gem variety of Corundum, encompasses all colors of Corundum aside from red. In essence, Ruby is a red Sapphire, since Ruby and Sapphire are identical in all properties except for color. However, because of the special allure and historical significance, Ruby has always been classified as an individual gemstone, and is never identified as a form of Sapphire.
- Chemical Formula: Al2O3; Color: Red; Hardness: 9; Mineral Class: Corundum; The chromium present in ruby causes a natural red fluorescence which is stimulated by both visible and invisible light. However, when a ruby contains a significant amount of iron in addition to the chromium, the fluorescence is reduced. Rubies naturally fluoresce stronger to long wave UV than short wave. Stones with the strongest fluorescence are often a pinkish red color in daylight.
