What is the name of a transparent semi-precious stone?

Precious stones have accompanied humanity since ancient times. Natural minerals were used to make magical amulets and talismans, carved figures of gods, and decorated weapons and dishes. Over the centuries, people began to decorate themselves with gems, and not only for beauty, but also to emphasize the nobility of the family and high position in society. Jewelry and accessories with colored stones have become an integral part of life. Gems symbolized luck, wealth and prosperity, and also helped people demonstrate uniqueness, chic and elegance. Today, the jewelry industry knows six precious stones and about a hundred jewelry and jewelry-ornamental minerals of varying rarity and value, all kinds of colors and shades with a unique pattern and texture. Jewelry companies are constantly striving to add new colors to their creations, expand the range of jewelry with a palette of shades and non-standard bright combinations. Color is considered the dominant parameter of any gemstone. This is the ability of natural minerals to transmit or reflect part of the visible spectrum. Color is determined by the internal structure, mechanical impurities, scattered inclusions of other minerals or organic substances. The coloring pigment in some cases is distributed unevenly, in stripes, leaving motley patterns (for example, in jasper). Along with rarity, hardness and purity, the color of precious and jewelry stones determines their value, and at the same time is considered the primary sign for determining the quality of the stone.
