I love a good druzy, don't you? Especially when it's amethyst!
 
These are amethyst heart necklaces I created with beautiful Brazilian amethyst druzy pieces. I made three of them in total. The back and edges are plated in pure copper with an aged patina and they have a protective coating to help slow the oxidation process. 
 
Copper turn you green? It's harmless, but annoying. To mitigate, simply paint your piece with clear nail polish where it touches your skin. It' won't hurt the crystal and it will stop the greening!
 
Each is about 2"W and comes on a 20"L opper chain with lobster claw clasp.
