The gobi agates I choose to use are smooth and rounded naturally, as the stones roll across the gobi desert they become rounded and soft. Specimen rings are made with natural stones, uncut and in their natural form, this gobi agate is approx. 3cm x 3cm and set in bronze wide band ring (approx. 1.5cm high) and can be a protective talisman. One of a kind, size 7.5-8.
