Exceptional in very good quality and Museum size, beautiful purple spherical Amethyst from Indonesia. This botryoidal Amethyst has exellent spherical form and in parts a microsrystalline surface giving a sparkly appearance. Condition is perfect. Very attractive specimen that displays well front and back. This is a high quality example from the find in 2016 which is often referred to as "Grape Chalcedony". Fantastic sharp color with amazing bright crystal. Most times this material is wrong labeled as chalcedony or as grape-agate - after serious scientfic studies we know that it is amethyste. The specimen is developed as floater and looks very tridimensional and aesthetic is each position.
