9.4 x 4.0 x 2.8 cm. A striking, very lightweight plate of a forest of tannish-white pseudomorphs of tincalconite after sharp, spiky, tabular borax crystals from the U.S Borax Mine of California.

They are so lightweight you really have trouble believing these are natural crystals, but they are. These are superb pseudomorphs. Ex. Mullane Collection.
ORDWAY-33 - Sulphohalite & Borax - $ 950 SOLD Searles Lake, near Trona, San Bernardino Co., California, USA small cabinet, 8.3 x 7.9 x 4.9 cm ex. Al Ordway
Perched beautifully on top a gray matrix of crude borax, is a well formed octahedron of lustrous and translucent, yellow Sulphohalite, measuring 2.4 cm in length. This is a superb, sharp, and colorful example of this very rare species from its type locality. It also happens to be an aesthetic specimen on its own merits. We have not seen such a nice example of this species in the overall quality level, before.
ORDWAY-34 - Sulphohalite & Borax - $ 600 Searles Lake, near Trona, San Bernardino Co., California, USA small cabinet, 6.2 x 4.4 x 4.1 cm ex. Al Ordway
Nestled aesthetically in a vug of borax crystals is an octahedron of lustrous and translucent, lemon-yellow Sulphohalite, measuring 1.5 cm in length. It is surrounded by by lustrous and translucent, colorless crystals of borax, to 1 cm across. This is a SUPERB, sharp, and colorful example of this very rare species from its type locality. It also happens to be an aesthetic specimen on its own merits. We have not seen such an example of this species in the quality level, before.
ORDWAY-36 - Sulphohalite & Borax - $ 750 Searles Lake, near Trona, San Bernardino Co., California, USA small cabinet, 7.4 x 6.4 x 6.2 cm ex. Al Ordway
A borax matrix is host to a single octahedron of matte luster, translucent, tan colored Sulphohalite crystal measuring 1.7 cm in length. In places the borax has started its inevitable, chalky white, alteration to the related species, tincalconite. An attractive and unusual combination piece - like several in the Ordway stash here, collected long ago and practically unheard of in such matrix-bound quality.
