cristal: 52,1 x 32,0 c 25,5 mm | Peso: | | Transparencia: | | Número de piezas: | | Origen: | La zona de Sakangyi, al oeste de Mogok, estado de Shan, Birmania (Myanmar) | Here you get two fine topaz crystals embedded in microcline. The microcline itself is twinned and shows fine crystal shape as well. The bigger topaz shows almost an inclusion free interior, fine luster on the prisms faces and sadly a small fracture, except this area no other damages are visible apart from the base. Nevertheless the composition of the specimen is very nice.
