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.
