Amazon.com Product Description If you haven't yet encountered the mesmerizing color of tanzanite, you're in for a genuine treat. Displaying a gorgeous deep blue color with a trace of purple, this unique gemstone becomes the star of any jewelry setting. This particular 7x5mm oval tanzanite loose gemstone has a weight of 3/4 carat and a sparkling faceted cut. A somewhat sensitive gem, with a hardness of between 6.5 and 7 on the Mohs scale, tanzanite should be worn carefully and kept away from harsh detergents and ultrasonic cleaners. A periodic gentle cleaning with mild soap, warm water, and a soft brush will do. The gentle care required is a fair trade for the spectacular colors this unique gemstone awards.
