This attractive mixed lot of sapphire crystals showcases the diverse habits and color styles of this corundum species. A very interesting assortment of a dozen crystals, all floaters. The largest is to 3.3 cm. Note there are several crystals of highly unusual habit here including both color and termination styles; and two very rare butterfly twinned crystals (upper row, rightmost and 3rd from right). Alone, those two twins, and the two or three larger ones, are well worth the price of the lot.
