$5,400.00


Description

DATE: Edwardian, c.1910

A breath-taking Edwardian brooch (with bail for wear as pendant) set with demantoid garnets and diamonds around a central natural pearl. The diamonds embellish gorgeous platinum foliate settings, with swirls of green garnets forming a backdrop. Exceptional quality and a striking design.

Demantoid garnets (aka green garnets or Uralian emerald) weren't discovered until 1868, when miners in the Russian Ural Mountains found an alluvial deposit ~110km from Ekaterinburg. Wikipedia cites that the "miners were stunned by the highly refractive nature of the gem material," which is another way of saying they're unbelievably bright and vibrant. Like, unlike any other green gemstone the miners had seen. The stones take their name from the French for diamond "demant" on account of their phenomenal brilliance and fire (their dispersion/fire is actually higher than that of diamond), and they remain prized and highly sought after to this day. So what you're looking at in this brooch are, technically, diamonds and "diamond-like" garnets.
