Thin orange crystals of Eosphorite to about 0.75mm with green Roscherite. Bery matrix, minor Englishite. Eosphorite is rather uncommon at the Tip Top mine.

Bright red bladed Montgomeryite crystals to 0.75mm in large groups giving that astonding red color. There is no other red Montgomeryite occurence that I know of, how about you? Whitlockite is associated with it as lilac groups.

Pahasapaite is one of the rarest minerals on Earth. It is only found at the Tip Top mine, and thus the type and only locality where it is found. The close-up photos show exactly where the glassy, pink crystals of Pahaspaite occur. This specimen shows more Pahasapaite than most others that I have seen, an area of 6x4mm. There are probably less than twenty or so in collections. It is nearly impossible to find one on the market these days. As is usual, it is associated with Tiptopite, Roscherite, and Englishite on Beryl matrix.
The specimen is one of the study pieces used for describibng the new mineral by Thomas Campbell and Willard Roberts at the School of Mines in Rapid City. It carries a Museum of Geology tag and also has a tag stating "New pink mineral".

Colorless to white sprays of Tiptopite to 1.5mm with red Roscherite. This is a fine specimen with excellent, complete and full radial groups of Tiptopite. Many of the sprays have nice orange, single Roscherite crystals gracing the Tiptopite. The white part on the right side shows a complete alteration of the underlying Beryl matrix which is only about 8mm thick. In fact anywhere you see the white matrix is altered Beryl. Elsewhere the underlying matrix is Quartz.
The Tip Top mine is still the only locality in the world where Tiptopite is found.

Superb, rhombic and colorless crystals to 1mm with color zones to brown near the outer edges. The Whitlockite is on a bed of pale green carbonate apatite on smoky Quartz. The Tip Top mine is perhaps the best locality for Whitlockite.
