D05-69 - Smoky Quartz with Rhodochrosite and Bertrandite - $ 750 SOLD Kounrad, Karaganda Oblast, Kazakhstan small cabinet, 6.7 x 4.3 x 2.1 cm
One of the best examples from the locality that I have seen, with a sharp 1.8 x 1.5 x 0.5 cm disc-shaped rhodo perched on the edge of a stunning smoky crystal!
M06-18 - Fluorite, Fluorapatite, and Bertrandite - $ 4750 SOLD Akchatau, Kazakhstan small cabinet, 9.2 x 5.0 x 5.0 cm ex. Martin Zinn
These unbelieveable combos came out in the late 1980s and were promptly sold as AQUAMARINE specimens....for awhile. However, they have retained a high value as phenomenal APATITE specimens, and espeically when in such beautiful combination they are hard to come by today. martin Zinn had the biggest stash of them from this small find,and the pieces such as this that came to market when his collection was dispersed are by far the best on the market in recent years. This is a great piece because it has good fluorite and good quality apatite, but also lots of it - making for wonderful color contrast against the crysatllized matrix loaded with white bertrandite. To this day, these remain one of the most desirable things out of Russia from the 1980s and 1990s.

This attractive matrix hosts 3 extremely sharp , translucent, euhedral bertrandite crystals including a twinned crystal. Although this species has recently been found in Kazakhstan, the crystal form is markedly different from these old classics of several decades ago (of which this is one). These are VERY rare on the market, today. 6 x 4.5 x 2.5 cm

Very highly representative of the species and locale. Ex. N.A. Wintringham Collection.
MD-249295 - Apatite-(CaF), Bertrandite, Albite (Var: Cleavelandite) - - Archived Golconda pegmatite, Governador Valadares, Doce valley, Minas Gerais, Southeast Region, Brazil small cabinet, 5.2 x 5.2 x 2.4 cm.
5.2 x 5.2 x 2.4 cm.

The apatites are very nicely accented by hundreds of sparkly, pastel-yellow bertrandite microcrystals. This is an excellent older combination specimen from this mine.

MD-38545 - Bertrandite - - Archived Golconda pegmatite, Governador Valadares, Doce valley, Minas Gerais, Southeast Region, Brazil small cabinet, 5.3 x 4.1 x 2.7 cm
This specimen hails from a onetime find, probably 25 years ago, and was brought out by Carlos Barbosa (from whom this specimen came). This is supposed to have been his best keeper, and stands on its own merit regardless as a superbly formed miniature with extremely large crystals for the species balanced on a bit of matrix . Irreplaceable! 5.3 x 4.1 x 2.7 cm
