Anatase on Quartz from Gouveia, Diamantina, Minas Gerais, Brazil [http://img.irocks.com/pics/jonas-22a.jpg]
Gouveia, Diamantina, Minas Gerais, Brazil
Small Cabinet, 6.8 x 4.2 x 2.9 cm
This bizarre specimen features a very unusual hollow anatase crystal of 1.5 cm next to an adjacent crystal of more typical habit. I have never seen anything quite like this. It is possible the anatase we see is a cast after an earlier generation, or even after a zircon perhaps, but I am not sure. The crystals sit on a quartz crystal (broken at either end but intact on the display face). In any case, the material has been analyszed and it is anatase now - a whopping huge one for Brazil, I would say. (obviously not a Jonas tourmaline but it fit in well with this update and was also at Munich...)
Anatase on Quartz from Mount Storenut, near Hardangervidda, Hordaland, Norway [http://img.irocks.com/new2010/LTH29C.JPG]
Mount Storenut, near Hardangervidda, Hordaland, Norway
Miniature, 3.5 x 2.8 x 2.1 cm
Outstanding, and truly first-tier, combination piece of a fabulous Anatase balanced upon a gemmy, pristine, Quartz crystal. Normally, the Anatases you see associated with Quartz are less than 1 cm, but this lustrous, euhedral bipyramid is an astounding 2.7 cm in length. The presentation faces are shiny, striated, and very sharp. There is some contacting on the base of the reverse side, but that is where it grea against matrix and it is otherwise complete. Considering the sharp, gemmy Quartz, and the magnificient Anatase-of-huge-size, this is just a killer! To me, it is one of the finest pieces in this collection. It is a toenail sized specimen (either a large thumbnail or a small miniature depending on how you angle it for display) ex Sam Nasser collection. Specimens like this are stunning examples of this unusual species, seldom seen. it is top tier.
Anatase on Quartz  (floater!) from Hyrdangervidda, Norway [http://img.irocks.com/pics/mz214a.jpg]
Hyrdangervidda, Norway
Miniature, 4.3 x 2 x 1.9 cm
This is one of the finer specimens of this mineral combination I have seen in recent years. Lustrous, deep blue-black crystals of anatase, to.75 cm, are aesthetically arranged on a transparent, gem crystal of colorless quartz, which measures 4 cm, in length. There is a minor ding on the back side of the termination, but, it is hidden when the specimen is viewed properly.
Anatase on Quartz from Valdres, Oppland, Norway [http://img.irocks.com/new2012/ORD40a.jpg]
Valdres, Oppland, Norway
Miniature, 3.1 x 2.5 x 2.1 cm
The presence of mirror-bright faces on a well formed 1.9 cm long, dark gray, anatase crystal, help make this specimen an unusually aesthetic piece . In addition, the anatase is aesthetically emplaced on a druse of nearly colorless quartz crystals. A minor bruise on the back of the anatase termination is not visible when the specimen is properly oriented, and overall this is a superb miniature.
