ELBA10-1  Elbaite with Lepidolite  $48  SOLD

Virgem da Lapa, Jequitinhonha valley, Minas Gerais, Brazil

4.5 cm x 1.6 cm x 1.2 cm

This piece is a doubly-terminated cluster of beautifully translucent, deep-green Elbaite : Na(Al1.5Li1.5)Al6(OH)3(OH)(BO3)3Si6O18 accented with interesting wheat-sheaves of Lepidolite.  Lepidolite is now considered a member of the Polylithionite - Trilithionite series as defined by these two end-members: KLi2Al[(F,OH)2|Si4O10] - K(Li,Al)3[(F,OH)2|AlSi3O10].  This piece was in my collection, and I never noticed until now that it has a small amount of damage on the back side only, near the top termination as visible in the second photo, hence the low price.

FL5-09b  Fluorite with Natural Etching  $18

Denton Mine, Goose Creek Mine Group
Illinois-Kentucky Fluorspar District, Hardin County, Illinois


2.3 cm x 2.1 cm x 1.4 cm

On the front side, natural etching has turned these Fluorites (CaF2) into thin, tabular crystals by preferentially removing material parallel to the crystal faces - note the thin edge that comes straight out towards the camera in the first photo. This highlights the dark phantom center that some of them have, as you can see by looking at the same feature in the second photo. On the back side, the etching has proceeded in the more usual fashion, working the Fluorite into finely grained and textured surfaces.

BPW9-11  Barite on Petrified Wood (A. Arizonicum)  $18

Petrified Wood Ranch, Puerco Ridge, Navajo Co., Arizona

3.6 cm x 1.2 cm x 1.0 cm

Feathery white Barite (BaSO4) on brick-red petrified wood from Araucaria Arizonicum, a conifer that is the Arizona state fossil.  The Barite fluoresces cream color under both LWUV and SWUV.  This specimen was collected by Ken Gochenour a couple of years ago.

MLC5-23 Calcite var. "Melicaria"  $35  SOLD

Julimes, Mun. de Julimes, Chihuahua, Mexico

7.5 cm x 6.3 cm x 5.5 cm

Benny Fenn brought these strange Calcites (CaCO3) in from Mexico and said that they form in cracks inside mudballs, similarly to the way septarian nodules (like the polished ones that end up as bookends) form. The Melicaria have very weak, dull orange-red fluorescence under a very strong SWUV source and even weaker under LWUV.

MLC5-24 Calcite var. "Melicaria"  $38  SOLD

Julimes, Mun. de Julimes, Chihuahua, Mexico

9.0 cm x 9.0 cm x 5.5 cm

Also available:
Four more in the 2 - 3 cm range for $15 - $18

Benny Fenn brought these strange Calcites (CaCO3) in from Mexico and said that they form in cracks inside mudballs, similarly to the way septarian nodules (like the polished ones that end up as bookends) form. The Melicaria have weak, dull orange-red fluorescence under a very strong SWUV source and even weaker under LWUV.  They aren't going to win any beauty contests, but I find these Melicaria fascinating!





MLC5-20 Calcite var. "Melicaria"  $35

Julimes, Mun. de Julimes, Chihuahua, Mexico

7.0 cm x 5.8 cm x 3.5 cm

Benny Fenn brought these strange Calcites (CaCO3) in from Mexico and said that they form in cracks inside mudballs, similarly to the way septarian nodules (like the polished ones that end up as bookends) form. The Melicaria have weak, dull orange-red fluorescence under a very strong SWUV source and even weaker under LWUV.

Mina Davidad, Rodeo, Durango, Mexico

5.0 x 4.2 x 3.4 cm

The most desirable form of Creedite (Ca3[SO4|Al2F8(OH)2] · 2H2O), in a sparkly, spiky orange ball (the photo is too red).  It will definitely attract attention to your mineral display .

BAR5-30  Barite  $22

Cavradi gorge, Curnera Valley, Tujetsch, Grischun, Switzerland

3.5 x 2.7 x 1.6 cm

By now it must be obvious that I really like Barite (BaSO4).  This is a neat little piece from a famous locality that few people would ever think to associate with Barite.

AZ10-7  Azurite  $22  SOLD

Malbunka Copper Mine, Areyonga, Alice Springs, Gardiner Range, Northern Territory, Australia

6.0 cm x 4.2 cm x 0.4 cm

Azurite (Cu3[OH|CO3]2) likes to form concretions, as in the famous geodes from the Blueball Mine in Arizona and many other localities. In this case, however, the concretion was forced to grow in a flattened manner due to the layering of Kaolinite (Al2Si2O5(OH)4) siltstone, producing an Azurite unlike any found elsewhere in the world.   The edges of this piece appear to be intact except at the bottom.

SM5-2 Smithsonite  $42  RESERVED

79 Mine, Gila County Arizona

4.6 x 3.6 x 1.8 cm

Decent-sized, apple-green Smithsonite (ZnCO3) crystals - NOT botryoidal masses as most of the specimens are - richly cover three sides of a shard of matrix from a very famous mine.

ANG8-1 Anglesite in Sulfur  $42  SOLD

Erupcion Mine, Los Lamentos, Chihuahua, Mexico

4.7 x 4.0 x 2.3 cm

Everyone knows Anglesite (PbSO4) from Tsumeb or Morocco, but Mexico?  Well, that's because these pieces are very old and don't get recycled often.  The Anglesite crystals are the tan rhombs.

CAL8-3 Calcite with Aragonite $35 SOLD

Dal'Negorsk, Primorskiy Kray, Russia

3.4 x 2.4 x 1.9 cm

I bought this Calcite for my collection from Viacheslav Kalachev many years ago.  It is rather unusual for an Aragonite (CaCO3) and a Calcite (CaCO3) to be present in the same specimen, since they form under different conditions (they are polymorphs).  But if any place can produce an Aragonite included in a Calcite, it is Dal'negorsk, the Calcite-collector's heaven.

HC9-2 Celadonite in Heulandite-Ca  $18

Jalgaon, Maharashtra, India

3.4 x 2.5 x 1.8 cm

A famous, but now largely played out, occurrence of the rare mineral Celadonite: (K(Mg,Fe2+)(Fe3+,Al)Si4O10(OH)2) included in the zeolite Heulandite-Ca: (Ca,Na)2-3Al3(Al,Si)2Si13O36·12H2O. This specimen consists of one large, compound crystal, which is unusual since most of these specimens are jumbly clusters.

ANA9-1 Anatase $18

Kharan, Baluchistan, Pakistan

3.0 x 2.5 x 1.6 cm; crystal size = 6 mm

A sharp, chunky Anatase (TiO2) crystal (the dark form on the top edge) on a matrix with Chlorite-included Quartz.  The big-name dealers were getting high prices for these after the 2005 find.

UVR5-1a Uvarovite  $35  RESERVED

Saranovskiy Mine, Urals, Russia

4.3 x 2.9 x 2.1 cm

Nothing else matches the color of a Uvarovite (Ca3Cr2[SiO4]3) Garnet, which is why these specimens are in such demand.

PSI5-5 Pyrolusite (formerly Psilomelane) on Goethite $24
The pictured specimen is sold, but there are 2 others:
PSI5-4:  4.8 x 3.9 x 1.8 cm;  $24

Luis Lopez manganese district, Socorro Co, New Mexico

5.7 cm x 2.5 cm x 2 cm

Hair-like Pyrolusite MnO2 formerly known as Psilomelane on a matrix of Goethite α-Fe3+O(OH).  This specimen is glued into a hinged plastic box, and I think that is the safest way to ship it.

APOP9-1 Apophyllite-(KF)  $28

Maharashtra, India

5.3 cm x 2.5 cm x 1.7 cm

The top side (left photo) of this unusual cluster of Apophyllites KCa4[(F,OH)|Si8O20] • 8H2O has some inclusion that renders it dark red-brown, while the bottom (right photo) displays mostly clear Apophyllites.  Note: the right photo shows a bit of the plastic stand holding the mineral for photography in the lower-right corner - that is not a crystal!
