Colors: The most common color of Aventurine is green, but it may also be orange, brown, yellow, blue, or gray due to inclusions. Oranges and brown Aventurines are caused by inclusions of hematite or goethite. Aventurine is often banded and a lot of fuchsite may render it opaque, which makes it be mistaken for malachite at first glance.
Mohs: 6.5 - 7
Chemical formula for quartz: SiO2
Chemical formula for hematite: Fe2O3
Chemical formula for goethite: FeO(OH)
Chemical formula for fuchsite: K(Al,Cr)2(AlSi3O10)(OH)2
Metaphysical properties: enhances creativity, and imagination, as well as intellect and mental clarity, prosperity, friendship. Brings luck, especially in games of chance.
I think this would translate to a gem that is creative, a thinker, maybe a philosophical like gem? But since Aventurine is a quartz it would most likely have been a warrior gem. But probably looked deeper in the reason why they were fighting. They would probably be lucky, but in away they wouldn’t notice like instead of winning the lottery they would never trip during a battle. Smarter aventurines would most likely use their luck and knowledge to count cards.
Where found: most green and blue-green aventurine originates in India. Aventurines that are creamy white, gray and orange is found in Chile, Spain and Russia.
Extra fact: The name aventurine derives from the Italian word “a ventura” meaning “by chance.”
