Lower New Street Quarry, Paterson, Passaic County, NJ

S-134  Stellerite  $55

Aurangabad District, Maharashtra, India

5 x 4 x 2 cm.

Fine crystallized Stellerites are only found in a handful of localities worldwide.  Stellerite is a species very close in structure and chemistry to Stilbite and can be mistaken for Stilbite.  Both Stellerite and Stilbite occasionally assume a bow-tie-like form.  This specimen is an example of this type of formation taken to the extreme and in my opinion that sets it above the majority of examples of these types of specimens.  The light-peach-colored Stellerite presented here has a good lustre and presents well in any number of different orientations.

A-107  Analcime  $40

Croft Quarry, Croft, Leicestershire, England, UK

4 x 3.1 x 2.6 cm.

A quite gemmy orange stained specimen of Analcime crystals to 1.4 cm. across.  The orange-colored mineral inclusions highlight the geometric form of the Analcime crystals.  A very lustrous example of this Zeolite mineral.

N-004  Natrolite and Calcite  $50

Sipi Caves, Mount Elgon, Manafwa District, Eastern Region, Uganda

7.1 x 4.2 x 1.5 cm

This specimen came to me as Natrolite on Petrified Wood and I guess that technically it is, as the rear of the specimen has a small stick of Petrified Wood embedded in it.  This specimen feature a plethora of shimmering Natrolite crystals associated with amber-brown-colored crystals of Calcite.  The minerals from this location are found in petrified wood fragments from a pre-Pleistocene ancient forest that clothed the Mount Elgon volcano.

T-317  Stilbite on Elbaite Tourmaline  $285

Himalaya Mine, Gem Hill, Mesa Grande District, San Diego County, CA

4.2 x 2.2 x 2 cm

 Here is an example of one of the more uncommon mineral associations that I have seen.  While Stilbite is not unheard of in pegmatites, it is not that common, but to find it associated with Elbaite virtually unheard of.  This Elbaite crystal is covered in a jacket of Stilbite crystals, measuring up to 1.5 cm in size.  These specimens were found around 1990 and were a one-off find.

A blocky and well-formed baveno-twinned crystal of Microcline featuring many tufts of divergent crystals of Stilbite.  Also present on this specimen are several crystals of Epidote measuring up to 1.7 cm in size.  There are also several areas with a red-colored mineral which appears to be Chabazite.  This specimen is a complete all-around floater with no damage.

Paterson, Passaic County, NJ

6.8 x 4.9 x 3.3 cm.

Stilbite with Celadonite inclusions, Jalgaon, Maharashtra, India

S-091  Stilbite with Celadonite inclusions  $70

Jalgaon, Maharashtra, India

11.5 x 6.4 x 4.6 cm.

This specimen features a pair of bow-tie shaped Stilbite crystals included by the mineral Celadonite. I've seen lots of Celadonite included Heulandite crystals, but not very many of these Celadonite-included Stilbites.  From what I have seen I have a feeling that there are not too many of these out there as I had to go through quite a few specimens to find this one.

A-109  Analcime with Natrolite  $30

Robertson Pit, Dayton, Mason County, WA

8.1 x 5 x 3.1 cm.

This specimen consists of clear to translucent crystals of Analcime measuring up to 1.2 centimeters on a matrix of Eocene pillow basalt.  Accenting the Analcime crystals is a 2.6 centimeter spray of Natrolite crystals.  This specimen was collected in the 1990's by prolific digger John Cornish whom amongst other things brought us the peach-colored Heulandite crystals on snow-white Mordenite from Idaho. Most recently all of those stunning Crocoite specimens from Tasmania, Australia.

H-011  Heulandite with Celadonite inclusions  $25

Jalgaon, Maharashtra, India

3.5 x 4 x 3.5 cm.

Here's one that in my opinion will be considered a classic in the future.  Slightly curved and twisted Heulandite crystals included by Celadonite.  These crystals have an extremely brilliant luster which many included minerals seem to lack.

AH-028  Analcime with Synchysite  $75
Ex Ron Waddell collection

Poudrette Quarry, Mont Saint-Hilaire, Québec, Canada

10 x 5 x 4.5 cm.

This large specimen, upon first glance, appears to be a rather typical-looking cluster of Analcime crystals, but this specimen is more than that.  The dark gray region is composed of hundreds of 0.5 millimeter disk-shaped crystals of the rare mineral Synchesite-(Ce).  (Ce is the symbol for the rare-earth element Cerium, for you non-chemists out there.)  Although some are naked-eye visible, the Synchesite crystals are better viewed with a loupe or a microscope which also reveals a sprinkling of minute Pyrite crystals, especially along the edges of the Synchesite discs.

Jalgaon, Maharashtra, India

8 x 6 x 3.7 cm.

Here's an example of a mineral specimen that in my opinion will be considered a classic in the future. This matrix specimen features slightly curved and twisted Heulandite crystals included by the mineral Celadonite. These crystals have a brilliant luster, which many included minerals seem to lack.

Krasnoyarsk Krai, Eastern-Siberian Region, Russia

12.4 x 11.2 x 5.1 cm.

A large specimen consisting of ocher-yellow Stilbite crystals.  These Lustrous crystals are interwoven with each other on their matrix.  The crystals on this specimen measure up to 3 centimeters.  This specimen is very 3-dimensional; more so than the photograph conveys.  These hard to find specimens were collected by the staff of the Fersman Museum on an expedition to this remote area some years ago.
