Gorgeous 1920s Cut Glass Turquoise or Blue Bar Brooch

Original Early 20th Century bar brooches, more than likely 1920s.
Gold tone metal bars with a cut glass imitation blue or turquoise gemstones.
I have 3 different styles - just 1 of each.
1. Big Oval Turquoise Stone, 4.5cm bar.
2. Smaller Oval Turquoise Stone, 6.4cm bar
3. Smaller Oval Blue Stone, 6.4cm bar
