Among the jewelry stones there are those that fall into the hands of a person from the sky.
One of the most common refining methods is the impregnation of gemstones with natural vegetable oils and resins.
Due to the different nature of origin, natural and synthetic stones have certain properties characteristic of a certain genesis.
Sometimes gemstones such as garnets, chrysoberyl, some beryls and other minerals may show signs of slight heat treatment, usually not able to affect their color and clarity characteristics.
