Olmiite from N Chwanning II Mine, Kuruman, Republic of South Africa [db_pics/pics/olmiite3a.jpg] Olmiite from N Chwanning II Mine, Kuruman, Republic of South Africa [db_pics/pics/olmiite3b.jpg] Olmiite from N Chwanning II Mine, Kuruman, Republic of South Africa [db_pics/pics/olmiite3c.jpg]



OLMIITE3 - Olmiite
$ 75.00

N Chwanning II Mine, Kuruman, Republic of South Africa
miniature - 4.8 x 4.3 x 1.2 cm

Once regarded as Poldervaartite, this mineral was later known to be Olmiite due to a higher concentration of Manganese than originally observed. This piece shows unique, bright barrel-like crystals on a matrix covered with druzy calcite. It is mounted on a 1 1/4" acrylic base (not pictured). There is a small ding on the mid right section of the piece, which is easily seen in the pics. Overall, a good sample of this interesting mineral.

STILBITE1 - Stilbite
$ 95.00

Jalgaon, India
cabinet - 10.5 x 9 x 6.2 cm

This Stilbite Specimen was found in the Deccan Plateau, in India. This ancient basalt flow is the greatest producer of Zeolites such as Stilbite. This is a fine example given its aesthetic crystallized 'spray.' The primary crystal is a creamy white color, and it's growing on a base of peach colored Stilbite. It displays easily without a stand, from several directions. For a common mineral, this is a superb example.

Danburite: Rough and Cut from Charcas, San Luis Potosi, Mexico [db_pics/pics/danburite1a.jpg] Danburite: Rough and Cut from Charcas, San Luis Potosi, Mexico [db_pics/pics/danburite1b.jpg]



DANBURITE1 - Danburite: Rough and Cut
$ 95.00
NET
Charcas, San Luis Potosi, Mexico
miniature - 3.2 x 2.6 x 1.7 cm

The Danburite crystal weighs 83 carats (16+grams) and the cut Danburite oval weighs 7.20 carats. Danburite crystals are notoriously damaged, and finding a sizeable one with no dings and some clarity is remarkably difficult. Danburite has a hardness of 7 - 7.5, and has a higher refractory index than a diamond, so as a cut stone it is quite sparkly. It is a Calcium Borosilicate, and it is taken out of a zinc mine by enterprising Mexican miners. Lately production has been very poor, with primarily "lechosa," or "milky" crystals being found. The entire chizel shaped termination is pristine. There is some side damage on the piece, but the clarity and intact termination makes up for that. I got the cut stone out of an old collection, it was facetted around 20 years ago. the price was right, so I'm passing it along. The two pics show the front and back of the crystal.

DATOLITE1 - Datolite with Quartz
$ 65.00

Dalnegorsk, Primorskij Kraj, Russia
miniature - 4.4 x 3.7 x 2.8 cm

This bright twinned Datolite is perched alongside a cluster of Quartz crystals. Many Datolites from this location are either dark and blocky or so light in color as to seem invisible. This example has a slight green tint. Some of the quartz crystals have broken off, but the centerpiece is the Datolite, which is in great shape (very tiny chipping along an edge, seen with loupe).

HEULANDITE1 - Heulandite with Stilbite
$ 95.00

Jalgon, Maharashtra State, India
small cabinet - 8.0 x 6.3 x 5.3

This beautiful piece shows the aesthetic combination of pinkish/peach Heulandite and orangy/peach Stilbite. Although zeolites from India are common, really good ones are not common. This is a really good one, that shows dramatic forms and bright luster.  It's in fine condition, there is a minor piece cleaved off one of the smaller stilbites (not eye-catching).
