Stunningly beautiful large Labradorite necklace

This huge stone is an absolute beauty! Gorgeous blues and markings going on. 
It's 2.5cm diameter surrounded by square shaped silver and I've  handcut a big star out of the back so both sides of the spine can be seen.  The chain is 16" long sterling silver with a silver lobster clasp.
This is really lovely and weighty and an excellent statement piece.
