This is a lovely piece.  The silver looks to have a nice anti-tarnish finish.  The central pink stone and the perimeter white stones all test as genuine sapphires on my Presidium Duo Tester.

My only complaint is that the chain is very slight and arrived very tangled; many people would not be patient enough to untangle the chain without breaking it.

Over all, this is a lovely sapphire pendant.  I am glad I found it for my wife.  It goes great with her pink sapphire ring.
