For both size and quality, this is one of the very best examples of the recently found bicolored Corundums from Madagascar. I exchanged it directly from Dr. Federico Pezzotta who collected it while doing research there. It features a 1.0 cmlong crystal perched smartly on matrix. These corundums are generally called sapphires on the market but to me, I cannot decide which to label them as. They go varying shades of red/purple and even to blue-purple depending on which lighting source you use to look at them. The effect is not subtle, either - its pretty obvious. 6.0 x 3.8 x 2.7cm
