A RARE SET COMPOSED BY A GEORGIAN RING WITH THREE INTERCHANGEABLE STONES.

End of 18th century

Stone 15x22 mm; int. diam 17 mm; 2,69 gr.

Probably German, attributable to Johan Christian Neuber of Dresden (circa 1790), an interesting set of three oval interchangeble hardstones (Agate, chalcedony) to be mounted in an openable metal gilded ring. Each of these colored and striated stones has an aesthetic particularity or a mineralogical curiosity. These kind of stones are referable to the "Cabinet of Lithologie" usually made in that period by a leather book-form case with marbleized interior, containing exactly the same kind of specimens.

Provenance: U.K. private collection
