This is a lovely (fox mine) turquoise pendant made by Paul Harrison measuring 33 mm x 25 mm x 4 mm. The pendant is mounted with a sterling silver spring bale and bell cap. You can get mass produced pendants from China quite cheaply, but these are all one offs, quite unique and made in the U.K. 

I have two fox turquoise pendants which i cut and polished myself. This particular one has a silver mounting, but i have shown a picture of the other one i have on ebay which has a fimo mounting as the last picture. These are the only two i have which are natural and not resin sealed and stabilised.

We have been in the crystal business for over 20 years and have a retail shop and warehouse where all our eBay items can be viewed before buying.
