C-255  Corundum variety Sapphire  $160  $100

Bawmar, Kyatpyin North, Mogok Township, Pyin-Oo-Lwin District, Mandalay Region, Burma

5.3 x 4 x 2.7 cm

Here we have an alluvial Sapphire crystal from one of Asia's more prolific gem producers. This crystal still has some of its matrix attached. This Sapphire has a medium-yellow color that is stained red by iron that has leached from the piece of the crystal's host rock that is still attached. Despite being river-tumbled, this Sapphire shows good form. This specimen would make a colorful addition to any collector's mineral cabinet.

AD-098  Opal  RESERVED

Yowah Opal Field, Queensland, Australia

7.4 x 6.3 x 3 cm

This striking specimen of “Yowah Nut” Opal consists of an ironstone nodule that is permeated by Opal of many different colors that it makes for a very colorful and aesthetic specimen. Photos do not do this specimen justice, when you hold it in your hands you will be amazed by the contrast of colors that this specimen has. It makes a great educational piece as well, showing in great detail how these “nuts” are formed.

G-125  Andradite Garnet with Epidote  $65  $45

Marki Khel, Spin Ghar Range, Khogyani District, Nangarhar Province, Afghanistan

5.7 x 3.5 x 1 cm.

This is one of the more weirdly-formed Garnets crystals that I have come across.  This specimen consists of a cinnamon-brown Andradite that looks as if it has been squeezed while it was forming and is accented by several small areas of pistachio-green Epidote.  This uncommonly-shaped Garnet is 100% complete all-around, has no damage with a great lustre as well as some areas where it is transparent.  Quite different from your usual Marki Khel Garnet specimen.

B-247  Emerald (double terminated)  $750  $525
Ex R. Rizzo Collection

Krupskoye Deposit, Izumrudnye Kopi Area, Malyshevo, Sverdlovsk Oblast, Russia

4.2 x 2.3 x 1.9 cm

A double terminated and richly colored Emerald Specimen from near Malyshevo, Russia. This specimen was mostly covered Biotite when I acquired it and after being prepared it was revealed that it possessed a good translucency and a pleasing inner glow with out being backlit. The upper termination of this Emerald dimpled on one edge. There is no damage to this specimen. The gem deposits in the Malyshevo area were first discovered in the 1830's. Since then the locality has provided superb crystals and gem cutting material of emerald and phenakite.

AH-028  Analcime with Synchysite  $125  $62.50
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.

W-024  Witherite & Barite  $185  $110

Nentsberry Haggs Mine, Alston Moor, Cumbria, United Kingdom

10.6 x 9 x 6.1cm.

This stout specimen of Witherite is larger than most from this mine.  The crystal is complete and exhibits a white coating which is an alteration to Barite.  The region of England known as Cumbria has a rich mining history that goes all the way back to the time of the Roman occupation and, for some time, been regarded as a mineral collector's paradise, being a prolific producer of more than 300 different species.  This specimen was recovered in the area of the mine known as Admirality Flats, more specifically the High Raise Second Sun Vein.

Morro Velho Mine, Nova Lima, Iron Quadrangle, Minas Gerais, Brazil

9 x 7.6 x 6.4 cm

This specimen hails from the world's oldest continually producing gold mine, started in 1725.  Present on this specimen are lenticular crystals of Dolomite to 2.4 cm. and very clear Siderite crystals to 2.0 cm. in size.  Most notable though, are the numerous crenellated Albite crystals measuring up to 3.3 cm. in size.  Albite is not often seen on specimens from this famous location, especially in crystals this large.  Both Siderite and Dolomite from Morro Velho are considered world-class in quality.  Also found on on this specimen are clear and gemmy Quartz crystals and the ever present Pyrrhotite.

A-124  Apophyllite  $85  $50

Mahodari, Sinnar, Nashik District, Maharashtra, India

5.8 x 5.7 x 5 cm

A stout and fully formed crystal of umber-yellow & brick-red Apophyllite. This floater crystal has a good form and a good lustre. These unusual specimens of included Apophyllite from several small finds in 2003-2004 became instant classics when they first appeared. Marketed as “Marshy Apophyllite” the inclusions were said to be Mozartite, a rare Ca-Mn silicate, but that has since been discredited. The inclusions were later determined to be clays or Chlorite. The red inclusions are iron oxides.

Minerva #1 Mine, Ozark-Mahoning Group, Cave-in-Rock, Hardin County, IL

9.7 x 6 x 5.7 cm

Crystals of this mineral species are much rarer than the massive form.
