Additional Info

Andesine is a somewhat new gem, first appearing on the market in 2003. It was originally found in the Andes Mountains of South America, hence the name. It is typically reddish and orange in color.

Where to buy?
For Andesine check what Amazon has to offer. You'll usually find quite a selection from many different vendors. Worth a check. For other high quality gemstones (Rubies, Saphhires, Emeralds) and especially Diamonds, I highly recommend JamesAllen.
