Solid cluster of intergrown Silver crystals, both herringbone formations and spine-twinned crystals. Nothing but Silver with crystals sticking out on all sides.

Large cluster of interconnected spheres of purple Amethyst known as Grape Agate. Good purple color with sparkly luster. Mounds of airy, interconnected spheres over a more solid, dense mass of interconnected spheres.

Aesthetic specimen of elongated Calcite crystals on Natrolite. A really neat piece collected by Chuck Trantham in 1961 and held in his collection ever since. The Natrolite has small dark inclusiions giving it a sptted appearance. Ex. Chuck Trantham collection.

Tall, snow-white crystals of Stilbite with Mordenite, complete and well crystallized all around. Ex. Chuck Trantham collection, self collected by Chuck decades ago during his time working as a geologist during construction of the dam.

Thick 'book' of Phlogopite (mica) from Otter Lake. Sharp, well defined edges with hexagonal form evident. Ex. Chuck Trantham collection.

Pair of intergrown, black Tantalite crystals from Colorado. Ex. Chuck Trantham collection.

Thick, euhedral 'books' of Muscovite on tan Siderite crystals. Cute USA thumbnail. Ex. Chuck Trantham collection.

Large translucent brown Pargasite crystals associated with blue Spinel. A superb California specimen, it was the best Pargasite (that I saw) from the Chuck Trantham collection, and there is nothing comparable to it on Mindat. The Pargasites are well formed and reach 2.1cm in size, with a band of blue Spinel (including crystals to 4mm) along the bottom, adding good color contrast. Chuck valued this at $750 back in 1983, significantly more than others in his collection that I saw, indicating he too rated this one highly. His label shows a locality of 'Locality No. 2, Twin Lakes area, near Lake Shore, Fresno Co., California' and indicates it was collected in August of 1983.
