CHRYSOPRASE AUSSIE ROCK
CHRYSOPRASE AUSSIE ROCK. This stone is not polished and is ready to be worked a little more and finished for a beautiful pendant or other jewellery piece. You could even leave it rough as a specimen. Pale green in colour and grinded on one side to reveal its beauty. A valuable and stunning Aussie gem stone, regarded as the best of the Chalcedony family. This piece is from Queensland. Nickel is what makes this stone green colour.
A gemstone variety of chalcedony (a cryptocrystalline form of silica) that contains small quantities of nickel. Its color is normally apple green, but varies to deep green.

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.

Fluorescent Specimens, Metal Specimens, Minerals of the World, Rock 'n Slabs, Slabs, Top ShelfWILLEMITE FLUORESCENT SLAB 02
A stunning specimen of Willemite Fluorescent Slab showing off the brightest fluorescence of all natural minerals Willemite. This rare special specimen is short and long wave fluorescent.  The dark grey metal shown in the natural light photos is Zinc ore Franklinite. The white mineral is Mangano Calcite, shows as Pink with UVA Long Wave and Orange with UVC Short Wave. The Willemite is Bright Mesmerising Green under both fluorescent wave lengths. Pics taken with shortwave, longwave, and sunlight. Very cool stuff and this is one of my very favorite rocks. This is a small high quality specimen with bright fluorescence at a bargain price. The Slab is intended as a specimen and may have natural fractures which may not make it suitable for Lapidary work.
To view this spectacular specimen’s fluorescent colours you will need a UVC Shortwave Lamp and UVA Longwave Lamp. Make sure you wear safety glasses. Willemite Franklinite Calcite is also known as the Christmas Tree Rock for the colours Green and Red. This is a quality collectable specimen with wow factor.
