Herderite - Hydroxylherderite
Conselheiro Pena, Doce Valley
Minas Gerais, Brazil
3.8 x 2.6 x 2.8 CM (miniature)
price: $220
An older specimen originally labelled as "Herderite" but without analysis it is more likely to be Hydroxylherderite. Either way this is a nicely crystalized Herderite series piece with 3 main crystals in a cluster, the largest being 2.6 CM. The crystals have glassy exteriors, are translucent and with strong backlighting show zoning with a darker orange core and lighter yellow exterior. Some minor contacts but no damage or bruises. Some thin cracks are seen in a few crystal faces these appear to be partly recrystallized under d magnification. There are no repairs, the specimen is solid and stable.
