This is a lovely amethyst cabochon that I have wrapped in copper wire. 
 
This dainty pendant is 35 mm long and 12mm wide.

This pendant comes with an 18 inch copper chain with a handmade swan's neck clasp.  It can be longer or shorter if you prefer - just let me know.

The necklace is presented on a handmade card in its own handmade paper bag.
