Clay inclusions in quartz are well known from Brazil, but this presents a cluster of stunningly lustrous and gemmy crystals, with surreal clay inclusions running around inside. Three dimensional, unusual, and extremely hard to photograph. Better in person! From the inclusions quartz collection of longtime dealer and collector, Ken Roberts.

An unusual new style of fluorite from this older district, these trickled out over the last two years at ever-increasing prices. This one is a superbly balanced small cabinet piece, with fat and juicy fluorites coming out at the viewer...more 3D in person. The green core on the underside of this fluorite combines to turn some of the deep purple fluorite crystals, a lovely shade of aqua when strongly backlit. The fluorite crystals, to 4.5 cm across, are all cuboctahedrons with great luster and translucence. Minor, bladed, white calcite is also present.

A gorgeous miniature fluorite of the new "tanzanite fluorite" find in China from the summer of 2017, in a hard size and price range to obtain. (Note the name is to denote the coloring of the fluorite and not an actual combination of the two species here.) This piece has a glittering crystal perched nicely atop a pedestal of sparkling matrix, with many gemmy crystals. The large crystal atop is complete, gemmy, and just under 2 cm across. On the closeup photos, you can see a small hairline crack and a few very tiny dings, that while present up close I did not even notice them at first - frankly the camera sees that more than the human eye. The piece is as much a "jewel" as you can want, and a great example of this pocket for a matrix specimen.

These large, sharp crystals are often called "tanzanite fluorites" in China for their unusual strong color, and that they do change color between sunlight and internal light to different hues ranging from blue-purple to purple. This is a large crystal measuring in at just over 5 cm across, perched atop smaller crystals. It has some contact in the bottom and the back, but is complete where it matters and presents that large, gemmy crystal front-and-center! These came out in 2017, and not since. The major crystal is fully terminated, even on top, and the photos here show it in different degrees of backlighting.

This fluorite specimen has a significant presence due to its substantial size and amazing, saturated green-blue color! It is a large, softball-sized, transparent to translucent, single crystal of fluorite showcasing two forms of fluorite: cubic and octahedral. The cube faces are prominent because they are flat, uncomplicated and lustrous. The octahedral faces provide a textural contrast since they are actually a product of at least octahedral and cube faces (possibly dodecahedral) competing for prominence resulting in an apparent "rough" texture. Looking face-on, the fluorite exhibits a saturated sea green color with a small, teal-blue phantom at the core! Upon close inspection, the periphery of the crystal displays a faint, teal blue color as well. Contacted on the back and bottom. An exceptional fluorite by any standard that displays prominently. I have been in this mine multiple times and can tell you, it is not easy collecting! Pockets are tight and 2 kilometers in. Crystals like this are few and far between. Color like this, is even more rare. Most crystals are much more pale, and the hint of blue is uncommon. From 2017 finds, not seen since.

Azurite on Matrix - Milpillas, Mexico

Azurite on Dickite - Milpillas Mine, Cuitaca, Santa Cruz Municipality, Sonora, Mexico
💎DM for pricing or email [email protected]

The Milpillas mine seemed to produce endless styles of azurites and malachites, but these crispy white matrix specimens really stand out. The main crystal reaches over 2cm, on a 5.5 cm matrix of dickite. The dark grey speckles haven't been tested, but are some sort of oxide (tenorite, perhaps?)

This is a combination specimen featuring a pastel blue fluorite with purple edge phantoms, 5 cm across, nestled in matrix of calcite. From recent finds in 2013, this combination is just unusual. In person, there are more subtleties of color and phantom edges that the eye picks up better than the camera. Joe Budd photos.

2018 Dallas Mineral Collecting Symposium

Museums represent the planetary repository of mankind’s heritage. In museums, collections are stored, cataloged and preserved over time, making them inestimable treasures. They constitute a material available for research, which can also be completed and reinterpreted over centuries. They permit to have access to all the wonders of the natural world. And behind these treasures, hides the willingness of curious individuals.

In France, we can trace the enthusiasm of having a national treasure back to François the 1st, who founded the French Crown Jewels in 1530. In the Europe nobility, “curiosity cabinets” were fashionable from the 16th century on. King Louis the 13th created his own in 1633, which eventually became the Museum d’Histoire Naturelle after the French Revolution. With this presentation, we will embark on a journey through French national collections and collectors of minerals and gems. From one museum to the other, we will discover some iconic pieces, as well as some hidden ones. We will follow the stories of some curators such as the Abbot Haüy (first curator at the Ecole des Mines) or some collectors such as de Bournon, Sage or more recently Vésigné.

Dr. Eloïse Gaillou is curator at the Mineralogy Museum of « l’École des Mines de Paris » (Paris School of Mines), now known as MINES ParisTech. After a Master degree in Geology / Petrology, she received her PhD in Material Sciences at the University of Nantes (France) studying opals. She combined her PhD with a DUG (Diplôme d’Université de Gemmologie), beginning her work on diamonds. Dr. Gaillou continued studying diamonds during her postdoc at the Smithsonian, then at the Carnegie Institution, both in Washington, DC. She took the position of associate curator at the Natural History Museum of Los Angeles County in 2012, before eventually heading back to France in 2015 to take the position at the School of Mines, where she oversees the collection of 100,000 specimens and takes care of the permanent and temporary exhibits.

This Jonas Mine Elbaite Tourmaline piece is all about cranberry color! The main crystal is 5.8cm in length and is saturated, translucent cranberry through much of the body with a deep magenta, gem termination and rises abruptly from a matrix cluster of six variably terminated cranberry Elbaite crystal along with some minor, white contrasting Albite, small book of Lepidolite and one tiny black and super lustrous Cassiterite crystal, whew! The vertical Elbaite in the same orientation as the large one is 3.2cm long and doubly terminated. No repairs to this beauty! Jonas set the standard, and has not been equaled since. A CLUSTER like this, without repair, is almost unheard of. Extremely colorful and elegant, it is a rarity. In 1978, the Jonas Mine produced what is probably the most famous single pocket of Elbaite Tourmaline crystals of all time and this crystal is a product of that discovery.

Tourmaline from Paprok, Afghanistan

Elbaite Tourmaline - Paprok, Kamdesh District, Nuristan, Afghanistan
💎 DM for pricing or email [email protected]

This impressive, glassy, polychrome Elbaite Tourmaline crystal from the renown gem pegmatites of Paprok, Afghanistan. This stout, striated crystal with other slender Elbaite Tourmaline crystals in parallel to subparallel growth starts with soft lavender-blue at the base and transitions to a pastel pink zone, then a 4 to 5mm medium green zone, a 4 to 5mm yellow-green zone, and a thicker blue-green zone at the termination. Super lustrous and striking. There is also a trace of tiny white Albite crystals on either side for accent. Comes with a custom engraved acrylic base.

Small Cabinet, 9.4 x 3.3 x 2.7 cm
Shigar District, Gilgit-Baltistan, Pakistan

Available : https://www.irocks.com/minerals/specimen/47933

This aquamarine has a strong "brightness" to it that is hard to capture and describe - just trust us that it is shockingly more sparkly in person than you expect, and not a typical quality. It is an intensely-colored and robust, sky-blue Aquamarine crystal with a Lepidolite rosette from the Shigar Valley in Pakistan. The Hindu Kush has produced some great Aquamarines and this one is very good! This impressive, completely transparent crystal is three and three-quarters inches long and an inch and a quarter wide with a glassy luster. It has beautiful sky-blue color, sharp prism face edges and natural longitudinal internal crazing that augments the reflectivity of the crystal faces! It has relatively sharp edges along the termination with remnants of Albite which slightly impairs a few of the corners near the top. A few nicks are present on the edges locally. For added interest there is a 1.3cm, elongated cluster of very pale lavender Lepidolite a third of the way up from the bottom. Contacted on and around the bottom. A spectacular Aquamarine that, in its size range, really stands out from others. It has to be seen in person to believe how sparkly it is - as if it is already cut and brilliant inside.

Twinned Calcite - Guangxi, China

Twinned Calcite - 884 Mine, Leiping, Guangxi Province, China
💎SHOP iRocks.com TUC12-671

This is a superb, exceptionally sharp twinned calcite from the famous Leiping Mine (where the more well-known V-twins were found in the late 1990s). This habit is fairly uncommon and usually the crystals are included, off-center, or otherwise marred. This piece is a perfect miniature with symmetry you could only wish for in most calcite specimens. It is gemmy and lustrous, and complete all around.

Gemmy and lustrous, this beautifully zoned toenail Elbaite Tourmaline crystal from Brazil displays a rainbow of subtle colors. The bottom portion of the crystal is gem clear with a yellow tint grading to pale gem pink into a wider, translucent, grass green zone back to pale gem pink then a gemmy green zone with at least two phantoms! A sharply formed and terminated, lightly striated Elbaite Tourmaline crystal with a couple of microblemishes and two patches of internal crazing. Lovely! VERY unique crystal from a single small pocket of about 2015

The shocking blue of Kelly Mine smithsonite is instantly recognizable, and this bright, botryoidal mass has a smooth, lustrous surface. At 11.5cm, this piece is a large example of the fine specimens found here, at this historic old mine that dates to the late 1800s.

This complete, polished slice is a cross section of a stalactite, showing concentric growth patterns. These are hard to find in complete rounds, as many have broken areas, missing "rinds," or didn't form rounds. Resembling a grapefruit, this hefty slice is 8cm across.

Available : https://www.irocks.com/minerals/specimen/47932

This a very choice, dark purple amethyst scepter with phantoms sitting on matrix with nicely formed Dolomite crystals and some minor Chalcedony. The scepter is the color of the purest grape juice, has numerous phantoms, displays silky luster and is pristine! It is 5cm tall, razor sharp, gemmy, and is perched nicely in a shallow pocket on matrix lined with 4 to 5mm, tawny Dolomite crystals (which is very unusual for Brandberg!) and a little white Chalcedony for accent. An exceptional Brandberg piece with no repairs or damage! Matrix specimens of this quality are uncommon.

Available : https://www.irocks.com/minerals/specimen/47929

Crazy cool Amethyst cast after Calcite from Uruguay that tells a great story! Initially a large, hexagonal-rhombohedral Calcite prism with a rhombohedral termination formed and was subsequently covered by a plethora of glassy, stubby, very pale to medium purple Amethyst crystals. At a later stage, subsequent to the deposition of the Amethyst, fluids came through the cavity and dissolved the the entire Calcite crystal leaving this marvelous cast. We know the initial history of the piece from the very sharply defined mold of the of the original Calcite crystal that left the telltale signs of its morphology. The individual Amethyst crystals are transparent to translucent and are very pale lavender at the base and rapidly transition to a medium purple at the tips locally incorporating what may be tiny (

💎DM for pricing or email [email protected]

White to clear Quartz crystals emerge from the base of this piece and gracefully transition into twisting spires of reverse scepters with purple Amethyst tips! This metamorphosis results in a very unique and artistic Quartz specimen from the Goboboseb region of Namibia. Several of the crystals have mossy green inclusions of Chlorite to add contrast, complexity and interest to the piece. Very showy! 5.6cm across, with crystals up to 2cm.

Mad Max Pocket, Malkhan Pegmatite Field, Chitinskaya Oblast, Zabaykalsky Krai, Russia

Available : https://www.irocks.com/minerals/specimen/47930

A fine, doubly terminated Malkhan Elbaite Tourmaline crystal with intense color! This two and a half inch, transparent-translucent, satin lustered crystal has a pyramidal termination at the antilogous end and pinacoid termination at the analogous end. The analogous end has a notable interior teal colored core with a jacket of deep magenta that dominates the rest of the crystal. This Elbaite is a bit deceptive in that its deep color and satin luster obscures the gemmy interior which is revealed even with minimal backlighting. There is some microchatter along the edges and both terminations have a couple of tiny nicks. Found, several years ago as documented in a recent issue of The Mineralogical Record.
