Dating to the 1920s/1930s or so (Art Deco period), may I offer this 18K White Gold (hallmarked as pictured) bar pin by Birks Canada. Set into the top gold setting is a single faceted round diamond shouldered by a pair of blue sapphires (most likely synthetic and entirely period appropriate). The back pinstem is hallmarked for 14K Yellow Gold. Length of the pin is 2-3/16"; width of the bar top is about 1/4" at the center. The white diamond measures 3mm (10 points) while the sapphire baguettes are about 8 points each (1.5mm x 3mm); total gemstone weight to the brooch is .26CT TW.
