Aventurine Rings
Aventurine is a form of quartz, characterised
by its translucency and the presence of platy mineral inclusions that give a shimmering or glistening effect termed aventurescence. The most common colour of aventurine is green, but it may also be orange,
brown, yellow, blue, or gray. Chrome-bearing fuchsite (a variety of muscovite mica is the classic inclusion, and gives a silvery
green or blue sheen. Oranges and browns are attributed to hematite or goethite. Because aventurine is a rock, its physical
properties vary: its specific gravity may lie between 2.64-2.69 and its hardness is somewhat lower than single-crystal quartz
at around 6.5.
