This is a striking yellow, translucent, dendritic chalcedony cabochon pendant. The photo does not do justice to the translucent, 3-dimensional appearance of the stone. Chalcedony, a cryptocrystalline form of silica, is composed of very fine intergrowths of quartz and moganite. This one is quite translucent, and has great coloration. It has great polish on both sides, and comes with a black pewter bail and an 18" leatherette necklace.
There are over 3,000 types of agates and jaspers, and this is a terrific representative of one of them! A great addition to your collection.
(As always, if you don't like the choice of bail or necklace, just contact me and we can make changes.
