Green Ocean Agatized Jasper with Crystalline Formations –...

Free-form carved and polished from a single block of ocean jasper from Madagascar. The specimen features a predominantly green structure, crossed by zones of chalcedony and quartz in smoky gray, white and beige tones, with small ochre and orange concentrations. The most distinctive part consists of a large olive-green area, made up of numerous closely spaced radial formations. These structures, resembling small flowers or crystalline rosettes, develop in different shades of green and become particularly evident thanks to the surface polishing. Among the formations there are some small natural cavities, left open during the silicification process of the rock. On the opposite side, the green gradually yields space to more translucent zones of quartz and chalcedony, with brown and reddish mineral inclusions. The different texture of the materials creates an alternation between solid areas, crystalline portions and light internal transparencies. The slender shape, with an asymmetrical profile and rounded apex, follows the original contour of the block. The flat base allows displaying the specimen vertically without the need for supports. Provenance: Madagascar Material: ocean jasper, chalcedony and quartz Work: free-form carved and polished Color: olive green, dark green, gray, beige and ochre Features: radial structures, translucent zones and small natural cavities
