Avanturin (sparkling, golden gem, Indian jade) is a kind of gemstone quartz. The color range varies from yellow, green, and blue to cherry and almost black. Avanturin differs in that it contains mica, goethite, hematite, and other particles. The rock of aventurine is also characterized by small cracks filled with iron hydroxides. As a result, the stone has a sparkling golden ebb and a soft shimmering luster (hence the names - "goldiskr", "sparkling").
This stone has been known for a long time. Even the ancient Egyptians tried to artificially create an aventurine made of glass with sequins inclusions. And they did it quite well. However, in Europe, the secret of manufacturing became known only in the XVI century, and even then quite accidentally (Venetian glass blowers dropped a little copper sawdust in the molten glass). Because of this whim of fate, the Italians called the stone "avventura", which means "accident".
The name has taken root. Although, for example, in the United States, aventurine is called the "Colorado golden stone". And in China, aventurine is called the "Imperial stone," and is considered sacred. And in India, aventurine is called the "Indian jade".
Avanturin is well polished and used very widely. In Russia, vases and candlesticks were made of aventurine, knife handles and forks were decorated. In England, they made large rings with a miniature portrait on the back side. In China, aventurines were used to make the imperial state seal.
Now aventurine is used to produce beads, bracelets, pendants, cufflinks, small carved figures and even massage balls. The current prices for this gem are not very high.
