VARISCITE

AUSTRALIAN

DEEP TRANSLUCENT GREEN

RARE GEM GRADE

Variscite is a hydrated aluminium phosphate.

Glenn Archer and David Vaughan made a significant, new variscite discovery in 2003 .

colours range - delicate lime greens to darker,

gem grade close to the colour of top grade chrysoprase, deep translucent emerald green.

The most unusual feature of the variscite is its association with gold. Gold is unevenly distributed in the variscite specimens, and ranges from discrete fine grains to visible concentrations in the variscite . There are also larger single grains in the rock matrix. Assays of up to 17 g/t Au have been returned from some samples

Much of the newly mined stone is also webbed....an added bonus as “spiderweb variscite” is a highly sought after material for cutting cabochons.
