Not to be mistaken by an emerald gem. An emerald gem is the green color
form of the mineral beryl. Small amounts of
chromium substituting for aluminum give it its
unequaled deep pure green. Be3 Al2 [Si6 O18]+ Cr2 O3
It is typically found
in prismatic hexagonal crystals that are usually
flawed and small in size. It is hard and durable at
about 8 on the Moh's hardness scale. |
