NOTE: After further testing the central stone has been determined to be a pink topaz and not a tourmaline as originally described.
A magnificent and rare Georgian era Portuguese ring dating to the mid-18th century. A rare heart shaped rose cut pink topaz in a closed back setting is surrounded by nine foiled rose cut diamonds, extending the heart motif outward. The heart is crowned with a tiara of five rose cut diamonds, with two additional rose cut diamonds at each shoulder. The stones are set closed-back in silver overlaid onto a gold mount, a typical 18th century method to prevent tarnishing the skin. The back of the setting is decorated in an unusual palm motif with the fronds spreading outward. The shank, or band, is pierced, a style that was popular in Portugal in the 1700s. The topaz is likely from the Minas Gerais area in Brazil, so named by the Portuguese due to its large deposits of gemstones such as imperial topaz, amethysts, aquamarines and tourmalines. The Portuguese incorporated topaz into magnificent pieces, many of which are in museum collections today. The Portuguese colonized Brazil in the 16th century, and named the area of Minas Gerais in 1720. Rare in its impressive size and style, its motif signifies love between the giver and the wearer. Given its exceptional size, it would have belonged to an aristocratic woman of means.
