Summary

[edit]
Description
English: Corundum
Locality: Zazafotsy Quarry (Amboarohy), Zazafotsy Commune, Ihosy District, Horombe Region, Fianarantsoa Province, Madagascar (Locality at mindat.org)
For both size and quality, this is one of the very best examples of the recently found bicolored corundiums from Madagascar. I exchanged it directly from Dr. Federico Pezzotta who collected it while doing research there. It features a 3.5-cm-long doubly terminated crystal perched smartly on matrix, with an adjacent fatter crystal. 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. These pcis were taken under both fluorescent and halogen lights to show the color change. 10.3 x 4.7 x 4.2 cm
