Large Butterfly Polished Agate Amethyst Geode

Heavy, weighs 1 pound 10.9 oz Geode is cut and polished professionally Please refer to pictures for size The outer size has some minor "scrapes" , thought I should point it out. The inner darker part is not chalcedony, it is metamorphic rocks. All natural, no treatment of any kind. It can be made into a butterfly.
