Bought this for my wife for Christmas. Her engagement ring is a tanzanite ring so I thought she would like this as a gift to match and belive me it's gorgeous! Tanzanite is nearly all mined out so finding a nice piece is very rare. The colour isn't the most bluest as you will be paying a lot more for to get the blue of blues so for the price you can't complain ! The chain isn't the thickest but I like it its dainty and really nice so overall it's a great buy for the price.
