Belcher rings became popular in the mid-18th century, named after the original designer, Thomas Belcher. A belcher setting is very distinct in that the diamond or gemstone is held by prongs or claws carved into the shank itself.This ring is a great example of the style, set with a central antique old mine cut diamond. And I just adore the smaller, more petite size! 18kt yellow gold, size 7 & fully resizable. Diamond is estimated to be M/N color & SI1 clarity. GIA standards.
