Sapphire Gem For Necklace Lab Created Fashioable Red Color

Sapphire, which is derived from the Latin Spphins, which means blue; it belongs to the corundum group of minerals in the trigonal crystal system. In the gem world, all colors of gem-grade corundum other than rubies are called sapphires.

The main component of sapphire is alumina (Al2O3). Corundum contains trace elements such as iron (Fe) and titanium (Ti), and presents colors such as blue, sky blue, and light blue, among which the bright sky blue is the best.

Synthetic rubies and sapphires are very similar in appearance and nature to natural sapphires, so it is difficult to distinguish them. Now mainly according to the sample internal package differences for identification, such as synthetic ruby often contains bubbles, fine arc lines and so on. If the package is small, these phenomena may not be observed with a magnifying glass, and an optical microscope is needed to observe the energy-picking resolution.
