Conchina means “little shell,” and these unusual pieces vaguely resemble seashells. These free-form crystal-studded pieces grew (geologically speaking) on the ends of stone tubes buried five or six feet underground. Some of them are backed by a mineral material that looks exactly like the shelf fungus that grows on hardwood trees. Some of them look like little ears, while others sport a series of concentric rings. Perfect for wire wrapping, these unusual pieces are sure to spark your artistic imagination! (For those doing prong-setting, unless otherwise noted pieces sit flat or nearly flat).
