A large cabinet specimen of hydrothermally altered parent Triphylite. On one side a large vug of 6 x 5cm is filled with dark pinkish red crystals of Hureaulite to at least 7mm. With the Hureaulite are great purple Leucophosphite crystals to 2mm. Large dark, dull black balls of Rockbridgeite also occur in this same vug. Most of the time Hureaulite from the Tip Top is a light pink, which is on the other side of this specimen.
On the flip side is another vug filled with light pink Hureaulite crystals to 1mm. These are associated with a light green Leucophosphite, which is a direct replacement of the Triphylite. But, a redeposited purple Leucophosphite fills the other half of the vug. That line of white crystals seen in the last photo is a group of Collinsite crystals less than 1mm in size. Yellow prismatic Jahnsite can be found along the fringes of the vug.
May cost extra to ship.

Simply beautiful specimen with purplish red micro Roscherite crystals upon which the pink clusters of Montgomeryite crystallized. The flip side features a little lighter Roscherite. On the edge, but not photographed are excellent pearly Englishite crystals. The matrix is Beryl.

The orange arrow points to an area with platy, dark red Robertsite crystals to 3 maybe 4mm. The blue points to an area of lilac carbonate apatite. The Robertsite was verified by Raman at the RRUFF lab and also was used for structure refinement. It is much different than most other Robertsite specimens, which usually form minute rounded crystal aggregates or pseudo-hexagonal prismatic crystals.

The green of Tavorite is much better in person. It is a small area where the green of the Tavorite is brighter lime green. The rest of the specimen is crystallized Hureaulite.
