Name(s) in local language(s):
Lavra do Urucum


Granite pegmatite.

Aimorés pegmatite district, Eastern Brazilian pegmatite province.

Discovered in 1962.

Sauer (1982, page 72):

A pegmatite situated between granite and mica schist concealed an enormous geode coated with kunzite and morganite crystals averaging 50 centimetres. The gemstones were accompanied by quartz with tourmaline needles, coloured tourmalines, garnets, lepidolite and columbite.


Note: Before being known as Urucum claim, it was called Tim mine.
