Specifications Physical Properties   Aventurine / 4MM Round Item #: GEM020226 Quantity: one / 15 inch strand Shape: round Material: aventurine Grade: c+ Treatment: natural Mohs Hardness: 7 Color: green Finish: gloss / opaque Size: 4mm Hole size: 1mm End to end hole length: 4mm 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.
