A superb, sharp, eye-visible and easily seen, 2 mm crystal of this extremely rare copper iodide species sits perched on contrasting green antlerite! . This crystal is gemmy, sharp, and easy to see. It is an excellent reference specimen of this, one of the more ultimate Chuqui rarities
An attractive specimen featuring bright green CRYSTALS of antlerite AND marshite on BOTH sides (front and back photos are shown in top row, left to right). All are gemmy and lustrous. This is a STUNNING example of the antlerite species that also features crystals of awesome quality! HOWEVER, the even more valuable mineral here is the extremely rare copper iodide, marshite; here present in the finest crystals you could expect outside of the type locality in Australia and frankly beating those, as well, for aesthetics. Chilean marshites are gemmy and clear, and sharp as heck. These GEMMY and SHARP crystals reach 4 mm in size! This locality is now defunct and important specimens are becoming increasingly more difficult to obtain. Marshite is one of the marquis species everybody is after, yet only a handful have ever been available for sale and few of such quality. 6.5 x 4 x 3 cm
4.4 x 3.4 x 2.3 cm. Marshite is almost never available to collectors, with most specimens either lost to the ages or already in museums. This is a very rich specimen, obviously validated, which I exchanged from the South Australian Museum last year (2008). The Museum label accompanies the piece. This piece features hundreds of sub-mm but eye-visible marshite crystals, on gangue matrix with small cuprite crystals. A very rich reference specimen for this important and very rare copper species (it is a startlingly simple copper iodide, CuI). When found, the mineral shows a pink coloration that faded naturally to colorless or beige over time (and now, is stable). Type locality.

Scattered on a gangue matrix are tiny crystals, about 1 mm across, or transparent, tan-colored marshite, a rare copper iodide. This is classic and very old material for the locality, hard to obtain today. Tiny stolzite crystals are in association. A great reference or micro specimen, for rarity. I buy all i see of this material
