Magnesite - gem crystals with minor Uvite
stock #8.AE-672
Bahia, Brazil
9.1 x 7.8 x 4.2 CM (cabinet)
price: $390

A super cabinet size display specimen of large, sharp transparent crystals of Magnesite. The Magnesites are highly lustrous and the largest exceeds 4 CM across. A few small yellow-brown Uvite crystals are scattered as well. Overall in fine condition, minor edge rubs are noted and the overall quality is top percentile. While Magnesite is a common mineral, good crystals are quite rare and are mostly know from a very few localities. Magnesite from the finds at Brumado (early 2000 era) have been considered as the best yet seen on the planet. The classic localities in Europe also produced some fine specimens are are treasured for the antiquity and rarity. However the Brumado Magnesites are known to be especially distinctive and are the crystals exceptional as this piece shows. While not really in any demand as a gemstone, some clear crystals like these have been faceted for the rare gem collector market. Since the deaths of some of the great collector/ dealers in Brazil (Carlos Barbosa, Luiz Menezes) there have not been more of these emerging on the market.

Magnesite with Uvite
stock #21.1-174
Bahia, Brazil
6 x 4.3 x 3 CM (cabinet)
price: $1200
Late Summer 2021

A killer, well crystalized Magnesite with the addition of yellow to green Uvite crystals from the now classic finds at Brumado. These are considered by most collectors to be the very best Magnesites ever found worldwide, and this is a superb example. This is a very early specimen from the first imports of the late Luis Menezes, and with a rare perfection and quality. The Magnesite is super clear, very sharp and the largest crystal is 3.4 CM. We have not seen any good or new specimens for the past few years. The arrangement of the rhombs on this specimen is especially esthetic and the Uvites are also glassy, colorful and add a nice contrast.

Magnesite- large crystals
stock #16.1-1289
Kaswassergraben, GrobBreifing, Hieflau
Styria, Austria
9.1 x 6.8 x 6.5 CM (cabinet)
price: $280
Worldwide mix summer

Very large to 5.6 CM across Magnesite crystals clustered on a Magnesite matrix from this classic locality. Kaswassergraben is famed for these rare and unusual hexagonal crystals unlike any other locality. This is an excellent example of a rare matrix piece with huge crystals for the locale. The back side is broken from the host rock but the front side main crystals present well with a fine pearly luster and stepped growth faces. I have not seen many of these and this is by far the largest crystal cluster I know of, other large crystals are usually about 2 CM at best.
