Opal (var: Opal-AN) / (var: Hyalite Opal) (“Blood Vessel Opal”)One of the most lustrous pieces in the update. Highly glassy beads of gemmy, orange to nearly colorless Hyalite Blood Vessel Opal from this new find in San Luis Potosi, Mexico. The inclusions are created by iron oxide and give the piece wonderfully strong red orange coloration and thin capillary like lines where the nickname Blood Vessel Opal comes from. A tiny bit of attached matrix makes for a great overall piece, and a worthwhile pickup for anybody

as is the case with the majority of Ferberites from Tasna

and very attractive for a smaller Gilman specimen

but the piece is even better in person

The largest compound group of Calcite crystals measures 7

Great condition all the way around

For all the Fluorites specimens that have come out of China

there are only about three places in the world today (Brazil

and the fact that there are THREE DISTINCT TWINS together

The largest sphere of Kowlezite measures 4 mm across

Great condition overall and it’s not often one sees such a fantastic blocky twinned crystal of Vivianite like this

not the main group

with very little luster and a somewhat stalactite-esque growth due to the way the Quartz overgrew the preexisting Laumontite
