Tanzanite – Natural, Faceted, Blue, 1.53 ct

This is a very pretty gem with great brilliance! Also, to the best of my knowledge this is an untreated stone. This is a medium color of Tanzanite, and is not cut at all deeply, so it faces up to look like it would weigh two carats or more. The more saturated color is coming in from the ends, which gives it kind of an interesting look. Also, this stone has a very noticeable shift from more of a blue in daylight, to more of a purple indoors. Color: Medium Blue-Purple, Cut: Brilliant Oval with Supernova Crown, Weight: 1.53, Dimensions: 6.7 x 8.8 mm. (Information supplied by photo contributor.) © Daniel Stair, CustomGemstones.com
