Size O on a ring measure, but due to the oval shape of the shank, it will probably fit a size P.  

7.8g. 

3 cm from North to South and 2.2 cm from West to East.

This is a well-balanced ring that sits nicely and flat on the finger. It doesn't roll as much as some of the bulkier rings do. I'm only selling because I don't wear it, and it really needs a younger hand.

The turquoise does have natural inclusions as shown, and the silver will have signs of use, but only as you would expect from a ring that is around 80 years old. 

It is not hallmarked, as is common with Navajo jewellery. I purchased it as silver from a long-established antique jewellery shop, and hae worn it without any issues.

Any questions, please feel free to ask.

Thanks for looking.
