I got an email today from a company that advertised all the colors of turquoise.. I'm rolling my eyes! there was Navy Blue, PINK! Prussian Blue and my "favorite" Violet! ( ICK!) .. OK to be fair they did say dyed.
but here's my take on turquoise:
Turquoise is only blue or green! There is no such thing as white,White Buffalo,purple,pink,yellow or apple green turquoise! Well they exist but they aren't turquoise.
Identifying turquoise:
Turquoise is copper aluminum iron phosphate, chemical formula: CUA!6 (PO4)4 OH8 4H20
Howlite is calcium barium hydroxide,
Magnesite is magnesium carbonate,
This misinformation of the trade is misleading and in my humble opinion criminal!
