Top 10 | Most Beautiful and Fascinating Opals Around the World

Dear viewers! Today we will traditionally talk about one of the most beautiful stones — OPAL STONE — The queen of all gemstones. Opal stone is a gem, colored as space, rainbow, and it indeed relates to something extraordinarily magical. Opal stone doesn’t have any crystal structure that other natural minerals possess. It ranks low on the Mohs scale of hardness. It is impossible to ignore the beautiful dance of colors that happens with every movement, called the opalescence effect. Rainbow modulations, changing at the smallest rotation of the opal stone, are caused by the refraction of light to submicroscopic particles of silica. The opals that experience such effects are called noble and go to the category of precious stones.
