This Gorgeous statement ring was found at a Bazaar in Bangkok Thailand, however this type of ring is from the Himalayas, so it is likely made in Tibet or Nepal.
The colorful inlay is made of real ground stones that have been set into the metal. The metal itself is non precious. It is made of brass with a silver colored finish on the outside.
On the underside of the ring there is some darker areas from the soldering, as seen in the photo.
Please note that this is approximately a US size 8 and is not adjustable because of the inlay work on the actual band of the ring.
