Epidote with Quartz
stock #AC 409
Green Monster Mountain, Prince of Wales Island, Prince of Wales -outer K
5.1 x 3.5 CM (miniature)
An super lustrous Epidote from Prince of Wales island, Alaska. This came from the stock of Schortmann minerals vintage 1960-64 and was part of the materials supplied by Ed Over. A very attractive specimen, there is contacting at the rear, but the display side is in excellent condition. Termination is composed of several parallel faces all of which are glasslike. The dark green of this comes alive with good lighting. A fine small classic US piece!
The very best example I have seen from this location. From the earliest finds here, this has been in at least 3 older collections before being added to John Marshall's. Striking and impressive with sharp, lusterous transparent and translucent blades in delicate rosettes having a 2nd generation crystallized over them. Individual crystals reach 4.5 CM. Pale blue to cream in color, in pristine condition, and simply esthetic. A fine addition for any California or Barite suite.

This is about the best crystallized stellerite I have seen from anyplace. We don't select Zeolite minerals for our inventory unless they are really exceptional. This is, very esthetic with sharp, deep colored translucent crystals well placed on a contrasting matrix. Except on the outer perifery, there is no damage. Deep orange-salmon color (may appear a bit too reddish on some monitors) these are distinct prism and not the usual clusters and bowties. From a now classic series of finds in a remote zone of NSW Australia. Pretty enough for a non Zeolite lover!
Ex Yale University collection and JH Marshall. An exceptional old classic specimen! A big, showy, well crystallized and heavy specimen of these rare Silver Chloride/Iodide species. Broken hill has produced the very finest of these minerals and both species are well presented in crystals up to 4mm densely packed. A rich yellow to waxy green color, the specimen is sawn on the backside and shows the matrix as a pure translucent green Mass. The old Yale labels (included) call this Cerargyrite which was in use in the 1950's and earlier. Far better in person and price well below the tags we have seen on many lesser pieces.
From the 70's vintage finds at this classic Northeastern location, this a very well presented specimen of top shelf quality. We have handled several good specimens with much larger crystals but this degree of completeness and perfection is unheard of. The main crystal is 3.6 CM long, complete all around, sharp and doubly terminated. Very well trimmed out, the crystals stand out from the matrix in an esthetic display. Not a colorful and flashy specimen, but incredible for the specie and location!
A large fine plate generously covered with sparkling gemmy crystals, ex Elling collection.Both sides of this curved matrix are covered with these Chabazites, the largest is 1 cm but most are about 5-6mm. A slight bluish tint is visible but otherwise these are near colorless, glasslike and in perfect condition. A fine Australian example of this less common form of Chabazite that is quite showy.
An excellent miniature with fantastic contrast and deep green fire color. The single emerald crystal (1.2 CM) is doubly terminated, one end with a classic basal form, the other is complex and partly contacted. The dark matrix is a druze of calcite and a few larger clear dolomite crystals that act as a strong color contrast to the deep green of the emerald. A striking piece, the crystal has no damage under 10x magnification. Well below market price for this level of esthetics!
An excellent small miniature with intense color and top shelf form. The Emerald here is 1.8 CM long, rich deep green (far better than shows on my monitor) and very sharp with glass like lustre. By naked eye this is no visible damage but a 10X magnification shows tiny chipping at the rear, contacting or zones of interrupted growth and rough areas near the base of the crystal. Still a fine quality display piece for any level of collection.
