Definitely hand made piece as I can clearly see signs on the ends and in the shaping. Unfortunately it was polished on the top but inside still shows age. It measures 6.25 as is. No markings but tested at 925 as shown. I believe this is a Royston turquoise as they are know for the copper/brown matrix.
I make no artist claim. I can only tell you this came from a huge estate lot of got from the state of Washington. This was separated to Native American.
