A 1.2 and a 0.8 cm crystal of tantalite, which is extremely rare from any mine in San Diego COunty and notably so from the Elizabeth R. From the collection of Roland Reed, mine owner (the mine is named after his daughter). This is a VERY IMPORTANT locality specimen

GEMS-058 - Manganotantalite (outstanding stone) - $ 10000 SOLD
Afghanistan
thumbnail, 15.78 x 10.88 mm ; 8.35 carats

This stone for all intents and purposes, is one of the finest facetted Manganotantalites in the world. For years, the only two regions that produced gem grade Manganotantalite were Minas Gerais, Brazil and Alto Ligonha, Mozambique. In recent years, we have seen some spectacular Manganotantalite coming out of Afghanistan, and the color is as rich and vibrant as any other locality. This gem is most definitely the finest cut stone of this material that I've seen from Afghanistan. Because of the density of this material, gems are often quite heavy, even in smaller stones. This stone has an intense blood red color, and there is no hint of brown to be seen, like many of the stones from Brazil and Mozambique. . The stone has a Cut Corner Triangle cut or Shield cut depending on how you view it. The stone is only very very slightly included. I would consider to be a world class gem and in the highest ranks of ultra-rare collector quality gems. This stone is virtually impossible to replace as Afghanistan truly has not produced much in the way of Manganotantalite rough in recent years.

An oustanding, dramatic twinned crystal of this rare earth species, showing great lustre AND form...rare in such a crystal. Also, most tantalites from Brazil are flat-topped and just plain brutish looking. This is as elegant as I can imagine a tantalite crystal to be! Note it is nearly pristine with just a few trivial dings, and otherwise it is complete all around. In some lighting, it acquires a surface iridescence, you can see. This is exceptional not only for Brazilian examples of this species, but for ANY locale

A sharp, 1.7 cm, lustrous, dark gray tantalite crystal rests on quartz-rich matrix covered with lepidolite and smoky quartz crystals. The large, translucent smoky is 3.5 cm and has an undamaged, frosted termination. I have never seen an Elizabeth R. specimen of this rare combination, especially the large tantalite!

MD-160203 - Tantalite-(Fe) - - Archived
Linópolis, Divino das Laranjeiras, Doce valley, Minas Gerais, Southeast Region, Brazil
large cabinet, 17.2 x 10.5 x 6.4 cm.

CLICK HERE FOR LARGER IMAGE:

17.2 x 10.5 x 6.4 cm. This monster is a COMPLETE, undamaged, 11-pound crystal (over 4 kilos!). It is fully and perfectly terminated and the fact that such a thing has survived s to me a minor miracle. The crystal is truly complete all around, and to me is a massively important mineral specimen for Brazil or a rare earth element collection.
