Summary

[edit]
Description
English: Corundum
Locality: Winza, Mpapwa, Mpapwa (Mpwampwa) District, Dodoma region, Tanzania (Locality at mindat.org)
Size: small cabinet, 6.1 x 4.8 x 4.5 cm
RUBY
Nestled in a vug of massive corundum is a lustrous and translucent, lavender to rose red colored ruby crystal, measuring 2.2 cm in length. Very aesthetic! This is a large, well-defined crystal of unusual size for this locality. Note the slight internal gradation to sapphire, visible when backlit. In normal lighting, it is a much more typical ruby color, at least on the surface zones. This larger specimen looks much better in person - quite dramatic in a case. The presentation of the crystal in matrix is more typical of other matrix gem crystals compared to the generally smaller examples we are otherwise seeing from this deposit.
