Aventurine Beads
Aventurine is found almost anywhere due to quartz being the most plentiful gem on earth. Aventurine beads are formed from Crystalline Quartz varieties of quartz that form large, well developed crystals. Rock Crystal Quartz is the colorless color of this species composed of pure SiO2. Rock Crystal Quartz can contain inclusions that color the gem; a tiny mica mineral within the stone can color the stone and the gem is called Aventurine.
