40.78 ct dendritic agate Cabochon- 8.91 g - (1)

Teardrop cabochon of translucent dendritic agate from India, 40.78 carats, with magnificent inclusions. It is set in silver metal and mounted on a modern 925 sterling silver cord-type chain. Exclusive variety of translucent agate with a magnificent miniature landscape of manganese oxide dendrites. This gem belongs to the quartz family (chalcedony). Its transparency is due to a pure infiltration of liquid silica into cavities of volcanic rocks. As the silica slowly crystallized, iron- and manganese-oxide-rich solutions filtered through microcracks, branching like roots or ferns, creating the illusion of a Japanese painting trapped inside the crystal. Guaranteed by a certified gemologist. It is shipped with a natural-origin guarantee (last photo). Customs duties outside the EU will be borne by the auction winner.

Estimate:£126.4
