SaiDian 1 Pcs Blue Tanzanite Stones Loose Gemstone for Women Jewelry Making Ring Necklace Beads Bracelet DIY Craft Making

Unfortunately the stone was slightly damaged as it was not protected during shipping and sent in a plastic bag then in a Amazon bag the pressure of other packaged caused damage to the cutlet of the stone no doubt the travel was from Michigan to Canada other then that and a windy day on delivery that sent me looking down the road to find it blown away into my neighborhood bush the stones very nice has a beautiful shimmer

The 10mm x 10mm works very well in a ring. The one I received has lovely color, no visible flaws but, under the loupe, a barely visible imperfection on one of the girdle edges. I will have no reservations in using this stone. Set in white gold, framed with small diamonds, this is a knockout piece.

The gem is fake, tanzanite should be trichromatic and change colour when viewed at different angles, this gem exhibits no colour change, even when compared with a real tanzanite sample, 1 out of 5 stars

For this price point, even being synthetic, this is a great value. Excellent color and luster and definitely looks like tanzanite as opposed to a lot of other cz synthetics which look like glass

Tested with a Presidium II. It tested as glass. I ripped into both Amazon and the seller. However, I just retested the stone prior to returning it and now it is testing as 10 a night. I apologize for my mistake.
