I would consider this Rajite as one of the better that I have seen. The cyrstals are well defined and the size of the crystals or crystal aggregates are to 1.5mm and the color is from a darker to light green. Rajite is named for Dr. Robert Allen Jenkins (RAJ) and has been found in only two worldwide localities. Excellent specimen!

Cryolite matrix with a lot of Siderite hosting many vugs filled with waterclear Thomsenolite and iron-stained, excellent crystals of Ralstonite. On the backside are minute single crystals, hardly noticeable creamy yellow Wulfenite, less than 0.6mm on "hagemannite", a mixture of limonite and thomsenolite. This is a very good combination specimen with good crystals.

Large ore specimen loaded with mostly dull, silvery Rammelsburgite with lessor quantities of brass colored Nickeline with a rosey tinge and tarnished Algodonite. The fact is all three are a little hard to tell apart and this would be a good study specimen with a SEM or a polished section. One side is cut and is likely has been well identified by polished section. Old David Garske label from Rapid City. One side as Annabergite alterations with bead like crystals a clear indication of the nickel content. There are also some bright red alterations (?), which is possibly Pyrargyrite but doesn't seem likely.
