This is a superb bustamite crystal not just for size, but for the sharp and complete termination. Usually these crystals are contacted or incomplete. This one, however, is complete all around (except for what may be a slight cleave on one narrow back edge) and shows an exemplary termination 6.2 x 1.7 x 0.9 cm
9.4 x 5.3 x 4.5 cm. Bustamite is actually fairly uncommon for the Kalahari district, and this is a rich specimen, with intense color. The soft pink hue is not pale…it’s actually quite strongly colored for a pastel hue. Charlie rated this highly, and said it was an unusually thick piece with the kind of color treasured for lapidary use, carvings and such. Ex. Charlie Key.
6.5 x 5.7 x 3.4 cm. Bustamite is rare for the Kalahari district, and this is a rich specimen, with intense color. The soft pink hue is not pale…it’s actually quite strongly colored for a pastel hue. The color is very similar to the rich pink Bustamite from the Franklin Mine, and the habit is a cross between Franklin's blocky crystals and the ''hairy'' Bustamite from Broken Hill, Australia. Good fluorescence. Ex. Charlie Key Collection.
A FINE, terminated bustamite crystal rising from sparing matrix, showing deep salmon-brown color, pretty good lustre for the species, and complete all around. Not at all common in this quality – a really good mini of this old and classic material from BH. These are just not around! 4 x 2.2 x 1.1 cm
9.1 x 7.8 x 5.7 cm. Intergrown calcite and massive bustamite are the matrix for prismatic, flesh colored crystals to 7 cm across, and the piece weighs about 500 grams. Bustamite is an uncommon mineral species in crystal form known best from this locality (old workings, though) and from Franklin in New Jersey. Specimens from each appear similar. The calcite even fluoresces in each case. Here, though, the galena crystals embedded in the calcite matrix give it away as Broken Hill material.
7.6 x 5.7 x 2.2 cm. A very rare polished specimen of classic "Dust Gold" associated with pinkish-brown Bustamite and Ferrobustamite set into massive white Quartz from the Idarado mine near Telluride. This specimen was analyzed by the late great mineralogist Gene Foord back in the early 1980s, and remains one of the only specimens of Bustamite/Ferrobustamite that I have seen from this mine. Ex. Richard Kosnar Collection.
6.6 x 4.3 x 3.7 cm. Bustamite is one of the few colorful minerals from Franklin that is found in reasonably good sized display specimens. This piece features several rather lustrous, thick, blocky, attractive pink colored crystals of Bustamite which are associated with blue Apatite and minor Calcite. The largest Bustamite crystal measures 2.7 cm long. These specimens are among some of the most easily recognizable and classic minerals from all of Franklin.
