This 5mm round Tanzanite, like all Tanzanite gemstones, was heat treated to arrive at this deep blueish gemstone with purple highlights.  Robert set the gem in a Sterling Silver Pendant which was one of his own designs.  
 
Tanzanite is a December Birthstone.
 
For this Pendant, we recommend an 18” or 20” Light Rope Sterling Silver Chain, #1120.
 
We'll be shipping this item in a very attractive Gift box and include a matching tote bag and crinkled paper. You'll be ready to present this gift in only a few minutes. All buttoned up, pretty, and sophisticated.
