Precious opal from Tacopa, Ca. Great for rock collectors. Found in the middle of the California desert not too far from Death Valley. The opals from Tacopa are in a clay like matrix. Small bits of precious opal flash through out this stone. None of the opal we found here was very big, but they sure have some beautiful flashes. It's hard to capture that in the pictures. Price is for this gem. I have more if you are interested please feel free to contact me. Small stone about 1 inch.
