A small specimen, with numerous black thorutite xls to about 0.8 mm. You will need 20-40X to view them. The xls are partly embedded in calcite and are not very imposing. But you will rarely see this mineral offered. World-wide, there are seven known localities but photos on Mindat only from Brazil and Franklin. This is from the initial find of thorutite on the Buckwheat dump made by Jim Rumrill ca 2000. Identified by John Cianciulli (curator of the Franklin Mineral Museum at the time).

There are three fairly distinct black xls of thorutite in the first photo. The largest (on the left) is 0.8 mm long. The xl on the right is about 2/3 mm long. The smallest (in the center) is only about 1/7 mm. Some of the other black blebs are very small or broken thorutite xls.

The second photo shows another xl about 2/3 mm long.

There are small thorutite xls, some broken, throughout the matrix. But they are not easy to spot until you know what you are looking for. I added an arrow (second photo) to help you get started.

Associated with orange-brown sphalerite and elongated pyrite. Some of the latter is tarnished and could be confused with the thorutite at first glance.
