This striking, sculptural, 360-degree, 3-dimensional boxwork is covered with both juicy and matte lustre, translucent, pretty violet to lavender amethyst botryoids. This fine piece is from recent finds in Indonesia. These caused a major stir at recent shows and are certainly beautiful, colorful and artistically fine specimens. Botryoidal amethyst is quite rare worldwide. Analysis by Dr. George Rossman at Caltech concluded these should be labeled as amethyst, and not chalcedony or agate. The scattered lighter colored attachment areas add color contrast and character to this colorful piece. A artistic and highly representative small cabinet example. See the fine article in 2018 The Mineralogical Record issue, Vol. 49, No. 6, pp. 827-836. Every turn presents a fascinating different perspective.
