Madagascar Rare Minerals
Schiavinatoite
This rare earth Borate is the Niobium analogue of Behierite (which
is listed further below). These are some remarkable examples
of this incredibly rare species. There are very few rare earth
Borates in the mineral world, and this is a great opportunity for
rare species collectors to cross this one off their checklist.

(which is listed above). These are some remarkable examples of
this incredibly rare species. There are very few rare earth
Borates in the mineral world, and this is a great opportunity for
rare species collectors to cross this one off their checklist.

Strüverite
This rare earth oxide appears not to be a valid species, but rather
a variety of Rutile. It is closely related to Ilmenorutile,
however the presence of Tantalum makes gives a very unique
chemistry. The below specimen is a good example of
this very rare mineral.

Rhodizite
Rhodizite is one of the more impressive rare
minerals that has been found in Madagascar. It has been found
in only three localities outside Madagascar: Ural Mountains of
Russia at Schaitansk, in England, and in Wisconsin. Before the
discovery of Rhodizite in Madagascar, the largest known crystals
were found in Russia and they only measured up to 1 cm. The
other two localities produced very little Rhodizite, and the
crystals were very small. Rhodizite is a rare gem mineral and
is highly sought after by gem and mineral collectors alike. It
forms a series with the newly approved species Londonite with
Rhodizite being the potassium end member.

Liddicoatite
Liddicoatite is a rare Tourmaline species named after the gemologist
Richard Liddicoat, the president of the Gemological Institute of
America. Recently, there has been a new influx of some great
specimens from Madagascar. There are more localities for
Liddicoatite in Madagascar than any other country worldwide.
Many of you are probably familiar with the great multi-color
polished slabs of Liddicoatite from Madagascar that show a wonderful
array of patterns and color arrangements, but typically Liddicoatite
is not often seen in euhedral well terminated crystals.
These specimens are excellent crystals for collectors as they
have excellent form, great luster and sharpness, and a beautiful
pinkish-red hue along the edges.
Enjoy !!
