MUSCOVITE MICA AUSSIE 1
Muscovite Mica Aussie 1 Specimen. Featuring many slim sheets of Mica together. This lovely silvery Mineral possesses special properties like electrical, thermal and electromagnetic insulation and shielding. We have personally measured these properties with a Trifield meter for shielding and Mica is one of the best natural radiation shields. It has been used scientifically for these purposes for well over a hundred years. Mica can be flaky and comes apart in thin sheets much like flexible plastic. It is a popular and unusual mineral that appeals to people of all ages. Muscovite is just one variety of Mica, named for the Russian province of Muscovy, known for its sheet mica. This specimen comes with the small dispay stand shown in one of the pics.

CHRYSOPRASE ROUGH CUTTING
Beautiful Chrysoprase Rough Cutting Aussie stone. An amazing colour for a rough stone of pale apple green. Once polished it will be quite striking. Usually reserved for jewellers, quality specimens like this are hard to come by and attract high prices. A great Aussie Gemstone. At 140g this is a larger specimen and worthy for any collection, but I think it will be made into jewellery. Some of the photos shown are back-lit with a torch to show the depth of colour and quality.
