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.
