Brassy, metallic Chalcopyrite crystals on translucent Siderite crystals from a limited find at the Kaiwu Mine in China. These were a one time find back in 2012 or 2013 and make stunning specimens due to the contrast in color and form between the Chalcopyrite and Siderite. The Chalcopyrite is bright and metallic with a slightly reddish irridescent surface coloration. The Siderite are translucent brown and lenticular in habit. There are also small white Dolomite crystals in areas. Fifteen cm! This is a large, museum sized specimen, which was unusual for the find, that is amazingly free of any damage (most were smaller and had some damage). This association hasn't been found since.

Large, intergrown rosettes of Azurite crystals from early production at the Shilu Mine in China. This is an old Al Ordway specimen and comes with his old label. Al was one of most famous California field collectors and a really fine mineral dealer. A complete all around undamaged floater with no points of attachment. Most of this find were singles with subpar luster and some damage. This is a very 3-dimensional piece composed of multiple intergrown rosettes. Better in person!

Intensely colored single Morganite crystal from Minas Gerais, Brazil. The Morganite has fantastic color and clarity with flat, glassy faces on front and top and a rehealed surface on the backside. Morganite specimens of this color and quality are impossible to find. It has a pure pink color similar to Madagascar Morganite, which is rare from Brazil. It also has gem rough potential and definitely escaped the cutter. 

Satiny to waxy, botryoidal yellow Smithsonite from the Philadelphia Mine in Arkansas. These so called 'Turkey Fat' Smithsonite specimens are usually seen as pseudomorphs after dolomite, and rich botryoidal specimens such as this are quite rare, this being the most impressive I've ever seen. The Smithsonite wraps around both sides of the specimen and is undamaged. The bright unique color is caused by inclusions of Greenockite. Only two localities have this color, texture, and luster (Sardinia and Arkansas) and if your buying one like this from Sardinia, add another zero.  

'The Sand Dune'...Lustrous orange Wulfenite crystals on matrix from Los Lamentos, Mexico. The Wulfenite have the best color for the locality and good luster and are nearly pristine with just minor edge chipping on some. The matrix is artistic, aesthetic, and unique. Drusy Calcite is studded with Wulfenite of the highest quality and color for the locality. A really neat feature is the wavy 'sand dune' like appearance of one side. Comes with a custom Lucite display stand.

Swiss smokey Quartz sets the standard for luster, clarity, and quality.  Add to this quality a single Quartz crystal pointing up to a twisted Gwindel.  When you combine  both a high quality single and gwindel Quartz, the rarity factor goes up exponetially.  I love mineral specimens such as this that are both unique and beautiful. By the way, you all do know that the guys that mine these things rappel and climb thousands of feet to get these. They risk their lives to get these mineral specimens, and that is one reason I appreciate them so highly.  It's complete all around and undamaged. The gwindel is fully transparent and has a good twist. Comes with a number of old collection labels including Gene Reynolds and Fred Pough.

Shiny metallic crystals of Bournonite from the Viboras Mine in Bolivia. The crystals are pristine and have bright silvery coloration, much more so than photos indicate - even better in person! The large cluster on top is 4.5cm wide and the intergrown pair of crystals below reach 3cm in size.  Comes with a custom Lucite display stand.

Gemmy orange Grossular garnet crystals with green Diopside from the Jeffrey Mine in Canada. The crystals are in magnificent condition, transparent and great sized for the locality, reaching 1.7cm in diameter. These are no longer being found and great specimens are getting harder and harder to find every year. Comes with a custom Lucite display stand.

Large, well formed Almandine crystals to 3.5cm in size from the famous and historic Russell garnet locality in Massachusetts. The crystals were collected from a small isolated pegmatite by two locals (Daniel Clark and F.S. Johnson) in the mid 1880s. The entire pegmatite was mined out at the time and the famous collectors of the era used to fight to acquire these. This is a fantastic, undamaged USA classic from a historic find. The specimens were sometimes prepped with black shoe polish - this has none.  Sawcut on back side. Comes with a custom Lucite display stand. 

Unusual, complete cluster of Wulfenite crystals from the classic Tsumeb mine. Most serious mineral collectors want something unique from the king of mineral localities, Tsumeb - this could be that specimen for many of you.  This is a 360 degree specimen. From the front the specimen has the appearance of multiple parallel grown crystals. From the bottom (last photo) you can see hoppered growth structure and hollow areas. The lustrous surface is coated by tiny yellow Mimetite needles and green hemispheres of Malachite. Tsumeb was a working Copper mine and it is a miracle that this speicmen survived in nearly pristine condition, I could fine just tiny edge nick.

Cluster of sharp, lustrous Azurite crystals from Tsumeb. The crystals are robust, high quality and good sized, reaching 4cm in length. The crystals are pristine with areas of natural etching. The emerald green Malachite and olive green Bayldonite are an artisitc color contrast to this magnificent piece. It's miraculous this specimen survived in this condition due to the fact that Tsumeb was a working Copper mine at the time this was collected. Great Tsumeb Azurites are not common - for every hundred Milpillas Mine Azurite specimens, there is one Tsumeb.

Coveted English 'heart twin' Calcite specimen from Egremont. This jewel-like crystal has faceted glassy faces on most of the sides with striated surfaces on the termination.  A floater crystal of the highest quality and a geological piece of history. 'Trust me these photos do not capture the jewel-like nature and qulaity of this specimen.'

Bold and dramatic bow-tie cluster of Arsenopyrite crystals from the Panasqueira Mines in Portugal. An exceptional example of a fairly common mineral, the cluster is complete all around and undamaged with bright, silvery metallic luster. Comes with a Lucite display stand. Ex. George Holloway specimen.

Outstanding specimen of a large twinned gemmy, lustrous Sphene (Titanite) crystal from Capelinha, Brazil. Large Sphenes are almost impossible to get in this quality. The main crystal is an impressive 8.5cm tall and has areas of both glassy and matte luster that adds a very interesting contrast to the specimen. There are smaller Sphene crystals attached to one side, along with a few small white Albite crystals. A floater, complete all around and undamaged.

Intergrown pair of color zoned Fluorite crystals on matrix aesthetically crowned by Celestite crystals. The Fluorite crystals are pristine, reach 3.5cm in size and have rich color with high luster. Highly artistic example with great balance and form. In my 25 years in the mineral business, I can't recall a Clay Center Fluorite I've liked more than this.

Glassy apple-green crystals of Apophyllite in an absurdly aesthetic bow-tie cluster.  This specimen is the epitome of natural art.  The cluster of Apophyllite crystals are perched dramatically atop peach colored Stilbite crystals. In the world of Apophyllite specimens, one in thousand is a bow-tie formation. Of those few, 99 percent have damage of some kind. Do the math, this is a special and rare specimen. Comes with a custom Lucite display stand.

Classic lustrous brown Pyromorphite crystals on a Galena rich matrix from Bad Ems, Germany. Ex. John Sinkankas specimen and has his collection number ('JS PYM 2) painted on the bottom. This specimen is also illustrated on page 421 of Sinkankas' famous book 'Mineralogy for Amateurs'. John Sinkankas was a legend in the field of mineralogy, this is your opportunity to own a piece of history along with an excellent, classic mineral specimen.  Comes with a custom Lucite stand.

Elegant specimen of a faden Quartz crystal on a matrix of non-faden Quartz crystals from Pakistan. For my taste, this single isolated faden attached to prismatic Quartz crystals is over the top aesthetically. The faden is 5.5cm tall and absolutely perfect, a stunning and highly artistic example. Comes with a custom Lucite display stand.

Stunning and important Benitoite/Neptunite specimen from the Gem Mine in California. This specimen is composed of a flat schist matrix partially covered by white Natrolite hosting two large Benitoite, Neptunite, and a single Joaquinite crystal. The largest Benitoite is 3cm wide (and the second crystal is not much smaller). The truely great Gem Mine specimens are composed of Benitoite, Neptunite, and Joaquinite on white Natrolite - this specimen checks all the boxes. This visually appealling specimen was in the personal collection of the late California mineral dealer Al McGuinness. Al was an active dealer in California during the heyday of Benitoite mining and had the opportunity to select the best. The fact that he kept this particular specimen speaks to it's exceptional quality and visual appeal. 

Sculptural specimen of gem quality Morganite from Brazil. This has been naturally etched in the pegmatite yielding this remarkably formed specimen. There are a few hard to notice chips, including on one side of the upright top crystallized section. Regardless, it has uncommon beauty and is a rarity. Comes with a custom Lucite display stand.

Colorful combination specimen of Inesite and associated minerals from the Daye Mine in China. Bright red rosettes of Inesite to 2cm in diameter are attached to clear Quartz crystals (most Inesite has a brown component that this one is lacking). Associated minerals include Pyrite and clear, tabular Apophyllite. Comes with a custom Lucite display stand.

Tall, slender crystal of Azurite partially pseudomorphed to Malachite with Arsentsumebite from Tsumeb. The crystal rises up off a 'matrix' of other partial crystals. The Azurite areas have glassy luster while the Malachite has a velvety luster, contributing to a contrast of textures and colors that work exceptionally well together.  A Tsumeb classic... Comes with a couple old labels, including one from Anton Berger (a German mineral dealer who specialized in Tsumeb specimens) and another that shows an old price of $1250.

Important blue/green to yellow crystals of rare Willemite from Tsumeb. The Willemite formed in a stalactitic fashion around Goethite. Willemite is one of the holy grail minerals from Tsumeb.  This well crystallized specimen actually has 3 distinct colorations of the Willemite - blue green, light green, and yellow/brown.  Of the Tsumeb classic minerals, the size and the form of this Willemite make it highly desireable to the connoisseur of classic minerals.
