Indian Green Sand Country of Origin - India

The Indian Green Sand stone is a form of aventurine. It is rich in chrome-like mica, which is no wonder that it’s found near a mica mine. Aventurine is a form of quartz, characterized by its translucency and the presence of mineral inclusions that give a shimmering or glistening effect. The most common color of aventurine is green, but it may also be orange, brown, yellow, blue, or gray. The mostly dark green with metallic glittery appearance is caused by inclusions of mica. Red to gold-brown is caused by the inclusion of hematite leaves. Because aventurine is a rock, its physical properties vary. Aventurine which is often banded and has an overabundance of fuchsite may render it opaque, in which case it may be mistaken for malachite at first glance.
