Indicolite – Natural, Faceted, Blue, 3.75 ct
In brighter light, such as sunlight, this tourmaline looks like a deep blue sapphire with a secondary green tone. I purchased the rough stone from a rock shop and it was in a parcel of material marked as being from Brazil. The clarity is comparable to the average Brazilian rubellite. It has some stuff in it, but nothing obnoxious or distracting. Color: Slightly Greenish Sapphire Blue, Treatment: None Known, Cut: Fancy Brilliant Emerald, Weight: 3.75, Dimensions: 9.91 x 7.54.
