Kyanites are generally thought of as dull, opaque crystals embedded in quartz, but once in awhile, you get a really superb specimen such as this that deserves a place in a fine collection. The crystal is gemmy, doubly-terminated, and sticking straight up from a shard of accenting quartz with the lower termination still mostly showing! It comes with a nice engraved acrylic display stand. I sold a larger version of a kyanite such as this in a recent update for around $600, and not only did it sell in the first minutes after posting, but 6 or 7 others emailed to buy it as well! So, I think we all realized how great the demand is for truly superb examples of this species that stand out as much as this one does. 4.8 x 2.1 x .7 cm
6.0 x 5.7 x 5.0 cm. A superb specimen from the Dave and Emily Stoudt Collection. Incredible, lustrous, iridescent, bubbly marcasite completely coats two, sharp quartz crystals. Colors range from rich gold to candy-apple green to reddish-orange. This specimen hails from the historic silver mines at Taxco.
6.5 x 4.8 x 4.1 cm. An old-time, classic specimen from the Herodsfoot Mine of Cornwall. Lightly iridescent bournonite cogwheels are aesthetically set on the crest and sides of a mounded matrix of lustrous quartz crystals. Historic specimens of this quality were recovered from 1850-1875. Ex. Borland Collection.
8.0 x 6.3 x 4.2 cm. Rose quartz is actually quite rare in nature, occurring in good specimens of display quality from a very few localities. This specimen has really pink rose quartz. It is not just pink quartz, but intensely colored pink quartz. It is classic for old finds from this prominent deposit for rose quartz found in the 1970s, and not often since. This piece is extremely robust and crystallized thickly all the way around except for some contacted portion on the left hand side only. Sharp crystals exceed 1 cm, and clusters extend to 3.5 cm in some directions. It is a very 3-dimensional piece, not a flat plate. Weighs 174 grams
A superb specimen of deep red hubnerite from the famous finds of the mid-1970s at the Huallapon, which remain TO THIS DAY the standard for the species in terms of lustre and form as well as that deep cherry-red color (visible usually with strong backlighting, but here at least you can see hints of it even in normal lighting). This pristine specimen has metallic lustre, and it is accented by gemmy quartz crystals at the base and along the backside. 5.7 x 2.8 x 2.6 cm
9.9 x 7.4 x 6.4 cm. Classic rich royal purple amethyst, to 9 cm in length, makes this a superb small cabinet amethyst cluster from one of the two famous Mexican locales. Color like this, and size like this, has not been seen in over a decade from this mining district. It stands as a unique style amidst all the amethyst fro mall over the world, instantly recognizable to the collector for these elegant, elongated crystals with purple shading to colorless tips. The major crystals are quite complete and 3-dimensional.
7.2 x 6.7 x 4.1 cm. The large crystal here is 3.2 cm, and fat, for a wulfenite from any locality. But it is a rare yellow wulfenite from the Mvouti Mine, worked in the late 1960s I am told. This is an interesting piece in that it is both large and has associated matrix - something not often seen. The contrast of the sparkling white quartz on yellow wulfenite is very interesting and unusual - again, I think unique to this locality.
4.0 x 1.9 x 1.8 cm. This specimen is a fine miniature size piece consisting of fine quality, sharp, gemmy, highly lustrous, prismatic, light purple color scepter, "reverse" scepter and simple prisms of Amethyst measuring up to 1.1 cm sitting atop white/colorless, modified rhombohedra of Calcite on matrix. This piece is remarkable for Bolivia as it is from an "Alpine-type" locality, and features a type of crystallization that is virtually unheard of from Bolivia.
4.1 x 2.9 x 1.4 cm. From the new find of 2007, this is another great discovery for this locality. This particular piece is a remarkable, very well crystallized, rare, specimen consisting of small, bladed, beautiful blue color, radiating aggregates of Vauxite coated by with a sugary "wash" of Quartz on minor clay (probably decomposed Allophane) matrix. This piece is from the type locality for Vauxite which was originally discovered along the Contacto and San Jose veins in this mine and first described by Sam Gordon and Mark Bandy.
2.6 x 2.1 x 1.4 cm. This mine has produced some very well known Rhodochrosite specimens in its history. This piece has some very attractive, pink colored Rhodochrosite rhombs forming "rosettes" which are associated with white Quartz "sprays" and minor sulfides on the back. The rhodochrosites are rather lustrous with that classic color that is well known from the Sunnyside mine. Ex. Richard Kosnar Collection.
5.3 x 3.5 x 3.4 cm. This is a very distinctive Creede Sphalerite association specimen. The Sphalerite is very gemmy with the typical honey and green color that one is accustomed to seeing from this mine, and they are associated with minor pinkish-purple Amethyst crystals and a few dull-grey cubic Galena crystals. The Sphalerite crystals on this specimen are very good sized for the mine. This piece was collected in 2004 (most likely off the dumps).
3.2 x 1.9 x 0.6 cm. The French Alps are renowned for their superb pink and red Fluorite specimens, but they also produce some superb Alpine Quartz specimens. This piece is a beautiful Quartz specimen as it has a distinctive "Faden" (string) running the length of the specimen. It has a pastel smoky color, but due to the razor sharp faces, crystal clarity and high luster, the "Faden" within is very easy to see. This specimen was recently collected on Mt. Blanc over the past summer (2008).
5.0 x 3.7 x 3.0 cm. Some of the finest crystallized Rose Quartz in the world is found in Brazil. This is a superb specimen featuring gem quality, lustrous, pink color crystals (one of them features a crystal within a crystal). Typically even small Rose Quartz crystals have a bit of a "milky" quality to them, but some of the crystals on this specimen are virtually water-clear. This specimen is about 20 years old (from the mid-1980s).
8.7 x 6.8 x 4.4 cm. The Tae Wha mine in Korea has produced some very attractive Tungsten minerals. The Scheelites from this mine are some of the most classic for the species. This specimen hosts a few large, sharp, lustrous, well-formed, purplish color crystals of Scheelite which are associated with an accenting Quartz crystal. The largest Scheelite crystal measures 6.7 cm on edge.
18.0 x 13.5 x 7.8 cm. Guanajuato amethyst is not familiar to most collectors, especially compared to the much more common specimens from Brazil, Bolivia, etc. This large plate of crystals came out of the collection of Dave Stoudt. The crystals are extremely clear and glassy, and the coloration is very subtle and unique: nearly colorless, but with very subtle strips and blushes of purple color towards the tips of the crystals.
