Locality: Winza, Mpapwa, Mpapwa (Mpwampwa) District, Dodoma region, Tanzania (Locality at mindat.org)
Size: 6.1 x 4.8 x 4.5 cm.
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. This is a large, well-defined crystal of unusual size for this locality. There is a 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. 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.
