Vintage St Justin 1980s Silver-Tone Openwork Brooch Blue Glass Mackintosh Pin

I like how this bar brooch borrows its straight lines and rose motif from Charles Rennie Mackintosh's Glasgow School designs.

A silver-tone bar brooch made by St Justin, signed in script on the reverse. The frame is cut in an openwork geometric pattern, with three oval blue glass cabochons set along its length.

St Justin produced Mackintosh-inspired jewellery through the 1970s and 80s, reworking the Glasgow architect's linework into wearable pieces. There's no date mark, but the design and construction place it in that period.

The elongated bar shape sits well along a lapel or a narrow neckline, and the roll-over catch holds securely on lighter fabrics. It reads more architectural than delicate, so it pairs naturally with a tailored jacket or a plain wool coat.
