Metal: 10k yellow gold, Marking: 10k / PALLNTI, Stone: shell cameo / onyx, Setting: bezel, Measurements: cameo 15.3 mm x 7.45 mm, onyx 15.4 mm x 7.6 mm, width of face 20 mm, width of upper shank 3.86 mm, width of base 1.23 mm, Size: 5, Weight: 2.2 dwt. NOTE: The cameo is slightly loose (moving upward and downward) but it is secure in the setting. Due to the age of the piece, the bezel around the onyx is slightly worn. There is a darkened area at the base of the shank due to a sizing repair. It is not visible when worn and the ring retains structural integrity.
