Golconda Pegmatite district, Governador Valadares, Doce Valley
4.8 X 2.3 CM (small cabinet/large miniature)
A single blocky well terminated crystal with very good lustre. Good sharp Columbites are not common and since its a very brittle mineral there is often lots of damage. With the high prices of Columbium, few good crystals survive now. This is from a find in the 90's Far better than average, very sharp with the termination complete and undamaged. There are a few natural cavities and pits on some faces, undamaged except at the base area where it was removed.
Unusual light violet termination on a deep green prism that sits on a shard of matrix. A few scattered crystals of clevelandite are on the tourmaline as well. The crystal is 7 CM long and the termination is complete with minor contacting, mostly on the back side.Displays well and a very good value for an unusual color combination.
