Old pink gold chalcedony blue gray adularescent ring and pearls

Ring in 18kt and 9kt rose gold (clover hallmark) decorated in its center with a beautiful cabochon of adularescent chalcedony, the color of which varies according to the light from gray to blue through shades of orange-pink, in a surround of small fine pearls mounted on wire. Remarkable 19th century work for the central motif which is in 9Kt gold. More recent reassembly in a ring whose square base in 18Kt gold ensures good positioning on the finger, thus preventing the central motif, which is quite bulky, from rotating. Gross weight: 7.20 g Height: 2.80 cm Ring size: 56 (diameter 17.75/ US 7.50). Changeable. Condition: very slight oxidation of the gold parts, and traces of soldering, see photos.
