Wuzhou Yongjian Yüksek kaliteli Yuvarlak Şekil 8 #Ruby cevherleri

Ruby is the gem quality of the mineral corundum, one of the most durable minerals which exists, a crystalline form of aluminium oxide. Corundum has a hardness of 9 on the Mohs scale and is also extremely tough. In its common form, it is even used as an abrasive.
The most important factor in the value of a ruby is color. The top qualities are as red as you can imagine: A saturated pure spectral hue without any overtones of brown or blue. The word red is derived from the latin for ruby, ruber, which is derived from similar words in Persian, Hebrew, and Sanskrit. The intensity of color of a fine ruby is like a glowing coal, probably the most intensely colored substance our ancestors ever saw. It is no wonder they ascribed magical powers to these fires that burned perpetually and never extinguished themselves.
All colors of corundum except red are known as sapphires, which has created controversy about where ruby ends and sapphire begins, particularly in pink shades of corundum. In 1991, the International Colored Gemstone Association ruled that the lighter shades of the reddish hues of corundum should be included in the category of ruby.
