This standing Volcano Agate cube measures approximately 2.9" x 2.8" and weighs 1.72 pounds, making it a substantial, self-displaying accent for a bookshelf, desk, or collector shelf. Polished to bring out the stone’s natural mineral patterning, it features areas that fluoresce a vivid green under a 365nm UV light, adding a surprising “hidden” layer of beauty that only shows up when you shine the light.
Equal parts décor piece and conversation starter, this cube is perfect for collectors and rockhounds who love specimens with a little extra science built in—an eye-catching display in normal light, and an unforgettable glow piece under UV.
