Russian Charoite Slab

Deep Purple Chatoyant Russian Charoite Slab

This is a fantastic unpolished slice of Russian charoite. It is a high quality piece with gorgeous, rich purple and beautiful chatoyance.

It's not natural, but where a core drill once cut through the full chunk of stone. It measures apx 4 1/4" at the longest point diagonally x 1/2" up to 2" thick and 1/4" thick. Weight is 2.6 oz, or 73 grams. Photographs were taken wet and dry..

Purple Dumortierite Lapidary Slab

Purple Dumortierite Slab with Blue Spots and Tourmaline

This is a slice of purple dumortierite, with some blue dumortierite (spots), black schorl tourmaline and rutile in it, according to GIA analysis. It was acquired from an old stock collection. We have found some of the material polishes easier than other pieces, but it does take a polish; more effort may be needed to make it really shiny. It looks a little more purple than the pinkish tone you might see in some of the photos. (You can read more about this material, including the GIA analysis results here - Item #4587 below.

Bertrandite Slab

Purple Fluorite Tiffany Stone 4x4" Slab

This is an unpolished slice of Opal Fluorite 'Tiffany Stone.' The material is rare and is sometimes found in Bertrandite, a mineral with the element of beryllium in it. This piece has varying shades of a light purple to a deep, dark royal purple, and black lines. Some neat patterns in it, and just a beautiful slab as is. The slab feels nice and solid. There is a small open pocket, roughly 1/4" square, with sparkling crystals gleaming, and a couple tiny 'pin-prick' openings on the other side. It measures roughly 4" x 4" and just over 1/4" thick (7 mm). It weighs 173 grams, or 6.1 ounces. Gorgeous slab of this rare material.

Purple Dumortierite Lapidary Rough

4 1/2 lb Piece of Purple Dumortierite/Tourmaline Rough

This is a chunk of purple dumortierite lapidary material we acquired. By GIA Analysis, it has dumortierite, tourmaline and rutile, and other minerals in it. The material has similarities to 'Nevada Rose Pink/Purple Dumortierite' we have seen. There are different patterns in this piece, with a black area mixed in with a darker purple and an area of pinkish-purple as well. Most of this material is hard and does take a polish, but may or may not be able to achieve a good shine. It weighs 4 lbs, 7 ounces (2.01 kgs), and measures roughly 5" x 5 1/2" x 2".

Purple Dumortierite Lapidary Rough

Purple Rough, per GIA Analysis: Dumortierite - Tourmaline - Rutile
By the Pound ($10/lb)

These are pieces of some beautiful purple material (some purple/pink) with black; uncut rough we acquired from an old collection. Most of it is hard and does polish but may or may not be able to achieve a great shine without a lot of effort. Sizes: Most SMALL pieces (like for tumbling) are SOLD OUT. It is likely that most orders will have at least one 1 lb piece 3.5-5" in size OR LARGER, up to 6-8" possible (unless you contact us to request smaller specifically).

Contact us below with how many pounds and we will send an invoice, once you approve photos of what we select for you.

GIA ANALYSIS (Gemological Institute of America): 'Dumortierite, Tourmaline, Rutile and possible additional minerals.' (See last photo for official analysis.) We asked some questions after that and got an additional answer from them that indicated the black stuff in the small sample we sent was tourmaline, the stone is mostly fine-grained, and that they couldn't take the identification any further.

BACK HISTORY: We got this material from an old collection some years back. The person we bought it from said he got it directly from someone who had worked at what once was Kaiser Steel years ago (which had been located in that vicinity). That company would import manganese from South Africa for its steel production. His guess was that he could have collected this material from their mine dumps, and was possibly low-grade sugilite brought over because of the manganese in it. Whether the man got it from the dumps or elsewhere, we don't know. But while at a Tucson Gem Show more recently, we saw a good selection of 'Nevada Rose Pink/Purple Dumortierite' which this material looks like and aligns well with the GIA analysis. We originally offered the rough as a mystery purple lapidary rough, but finally had it analyzed as above. Some blue spots can also occasionally be found in a piece, as well as the purple and sometimes even a little more pink, which we think all could be the dumortierite. (The rough pieces of this material have a lot of weight that we still believe may be from Manganese in it.)
