A large, cut amethyst geode is displayed within an indoor exhibit, likely a museum or geological exhibition. The geode, approximately hemispherical with a rough dark grey exterior, reveals a cavity densely lined with varying shades of purple amethyst crystals, lighter towards the edges, and some white crystal formations. It rests on a dark, rectangular base, which sits upon a circular, translucent platform illuminated from below by a cool blue-green light. Behind the geode, a black informational plaque is visible through a glass barrier, featuring white Indonesian text identifying the specimen as "Kristal Amethis" (Amethyst Crystal), describing its nature as "Alamnya Quarts" (Nature of Quartz), and stating its location of origin as "Ciater Geologi." The background consists of a light-colored, textured wall, possibly marble or stone. The exhibit is located within the Museum Geologi Bandung (Geological Museum of Bandung) in Bandung City, Indonesia. No people or active interactions are present in the static scene.
