Circa 1870, this gorgeous French brooch features a pink tourmaline as its centerpiece, flanked by Rose Cut diamond studded triangles along a horizontal 18k gold pin. The tourmaline is oval-shaped and bezel set—it is a nice old cut stone with complex dusty rose hues. Elongated triangles radiate from the stone for a triangle-within-a-triangle effect. The inner shape is set in platinum, delineating and enhancing the white of the diamonds bead set within its borders. The outer triangle adds a layer of depth of the gold, making for an elegant and well-balanced geometric pin. 

The brooch contains unidentified French hallmark, along with an eagle head, the French mark for 18k gold. The tourmaline measures 8.5 x 7.5 and approximately 2 carats. The 10 natural Rose Cut diamonds weigh .10 of a carat. The pin measures 2 3/8” x 3/16” and weighs 6.2 grams. 

The back of the pin contains evidence of solder from an early repair. This piece would look great on the lapel of a jean jacket or leather blazer.
