Looking for a classic antique diamond solitaire ring?

This lovely was handcrafted in platinum with a central old European brilliant of about 0.93 carats in England in the early years of the 20th century.

A bright white fiery old diamond is complemented by three tiny old single cut diamonds on each shoulder, extending the central motif softly into the encircling band, with the aid of a finely milled edge.

The side view reveals a pretty, crown-like setting for the central stone and a delicate but sound overall structure.

We provide independent retail valuations on all our gemstone rings over 2,000 Australian dollars. Scroll through to see the details of this one.
