The British system of marking jewelry here tells much of the story of this diamond ring.

From the firm of A.W. Crosbee & Sons Ltd. of Birmingham, England, comes this antique vintage ring from circa 1930.

Studded with shimmering diamonds, it was created with a two-tone look in platinum over 18k yellow gold.

An intricate pattern to the top utilizes millegrain (beaded raised edges) and illusion-set natural diamonds to enhance the style. Its anyone’s guess where diamonds leave off and platinum takes over.
