This very pleasing ring would have been worn by a Tibetan man, most typically, but some were also worn by women. Often they were worn in the hair as a hair ring, as well as on the fingers.
It is of cast and chiselled silver with parcel gilding (gold plating.) The bezel is set with a large, oval turquoise cabochon in a silver box setting.
It is called a ‘saddle’ ring on account of its shape.
Similar examples are illustrated in Seiwert (2009, p. 171) and Hoek (2004, p. 173).
It is in fine, wearable condition and with obvious age.
