The sample is 4 cm x 3 cm. This is a better view of the foliated, purple tarnished Hedleyite from the quartz veins with Lollingite. The Hedleyite is quite soft and bends rather than fractures on the edges of the sample. I have not scratched the sample to reveal the perfect Hedleyite cleavage. Several smaller purple-tarnished crystals of ...

2.7 cm Hedleyite. Specimen is from the collection of the Smithsonian Institute, Msueum of Natural History 85382 (1975). Scale at bottom of image is an inch with a rule at one cm.

Hedleyite in quartz. Brent Thorne specimen and photograph.

The sample is 5 cm x 4 cm. Sparse 1 mm, very reflective, tin white, Hedleyite and 5 mm aggregates of tin-white Lollingite occur disseminated in a mass of brown Grossular garnet and brown Axinite Group encased in medium grained colourless Calcite. This is a sample of gold ore from the Oregon (French) Mine. Data from knowledgeable sources allow ...

The sample is 4 cm x 3 cm. Purple tarnishing Hedleyite and altering Lollingite have produced an unknown suite of green and blue secondary minerals coating the Quartz veins and as crystals in the vugs. I have not been able to find any information on these secondaries but the lack of sulfur in the system means they are probably arsenates or ...

A rich specimen of this rare telluride. Piece is 5.0cm across with 8mm individual crystals.

4.2 x 2.2 x 1.9 cm. Hedleyite is a rare bismuth telluride, which is found in only about two dozen countries in the world. Joseite-B is a rare questionable/doubtful species, according to the IMA. The bismuth, tellurium sulfide is named for its relationship to joseite (same elements with different amounts) and is possibly just sulphur-rich pilsenite ...
