As well as wearing a gemstone, it presents an exuberant play of color. The colors shine in all the individual corners.One of the main reasons that distinguishes opal gemstones from other gemstones is that opal is made of hard silica gel, not crystals.Opal is primarily mined in Australia, and 10% of the opal rock is mined in Brazil and Mexico. Although a pure opal stone is colorless, it is almost impossible to find a pure opal stone. It is the impurities that give the opal stone its color, ranging from black, red and blue.
