Purveyors of Fine Specimens,Gem Crystals, And Rare Gemstones

I purchased a set of three very unusual sapphire crystals from a Sri Lankan gemologist while in Tucson. These crystals are all flattened twins, with unusual blue and clear color zoning. She mentioned that these were recently found at Passara and, as far as she knows, she purchased all of them. This crystal is the best of the lot and measures 2.5 x 1.4 x 0.2 cm.
