About this piece

Crafted in 18ct yellow gold by the North American firm Hammerman Brothers, this bombe ring presents alternating panels of diamonds and mystery-set red rubies. The two ruby panels comprise 42 calibre-cut stones set on rails, a technique first mastered by Van Cleef and Arpels in 1933. The adjacent diamond panels hold 52 bead-set brilliant-cut diamonds of G/H colour and VS–SI clarity, with a total weight of 0.75 carat.

Mystery setting is a technically demanding approach to gem-setting, and the execution here reflects refined workmanship consistent with the maker. Hammerman Brothers began in 1946; this piece was likely produced in the later part of the 20th century. In very good order.
