CassiteriteA unique Cassiterite from this classic tin deposit in Bolivia. Viloco (sometimes called Araca) for many years has stood as one of the top Cassiterite localities in the world.

Specimen # BOL711B151

but good Augelite specimens are few and far between

Specimen # AMAZWH111920

Copal is classified as a "young amber"

PLEASE NOTE: There have been no more of these specimens found for many years from this locality

so it's not a broken "chunk"

with only a few small nicks to the Ludlamite groups

but please be aware that it does have nicks and broken edges

well-formed black and brown cyclic twinned crystals make for an appealing display piece

there are some small Cassiterite crystals that are actually “floating” inside the Quartz crystals
