SEDAGEMS

These are natural well polished stones from a volcano in Indonesia.This material is top grade as it has a amazing pattern.This is a recent find and supplies are limited.It is also known as mustard jasper

I selected these stones from a large parcel on my last trip to Bali-there are some stunning patterns in it.I listed some stones on our sister site in mineral gem world but these have a much better pattern.

This stone is the product of hydrothermal deposit at the mouth of a semi annually drowned volcanic vent. Its a mixture of high levels of silica in the form of primarily opal and acidic solutions that dissolve the wall rock of the volcano, as well as percolating sulfur out of the belching still active fumarole, as well as other minerals. These have been depositing for a few hundred thousand years at this high mountains vent. It is then essentially opalized and silicated sulfur as well. Mine source adds that as many as 15 other mineral traces color the blend in the gorgeous plumes you see within these crazy pretty cabs
