Cartier Chalcedony Tank Ring
ABOUT THIS RING
Sublime in its sleek simplicity, the clean bold lines of this vintage Cartier tank ring create a stunning structure that forms a seamless--and utterly harmonious--setting for the luminous chalcedony gem that glows at its center, reminiscent of a shimmering moonstone. Rendered in 18K white gold, currently ring size 4 1/4. Note: limited sizing because of placement of maker's marks.
