Donuts can be integrated into jewelry in many ways. Mini donuts, for example, are ideally suited to be incorporated into necklaces or to be placed in creoles. The large donuts act as eye-catchers on a longer ribbon and can be used in many other ways with the help of a Donut Holder.
The donuts made of carnelian (blood agate) are 30mm in size.
Other names for the mineral carnelian are coralin/coraline, flesh agate or blood agate; in wholesale carnelian is occasionally called serdolik.
