Kojis Kojis 15ct Gold Boulder Opal Bar Brooch | Luxury Gift | Brimming with character, this boulder opal bar brooch from antique purveyor Kojis reflects the fine craftsmanship associated with its maker murrle bennet & co. Capturing the spirit of turn-of-the-century design, it's set with a boulder opal cabochon in a smooth bezel. The opal displays a vivid play of colour, shifting from deep purplish blue through lilac and greenish blue, with bright green scintillating flashes. The stone is set within an elegant entrelac bar brooch, its flowing curves reflecting the organic lines typical of art nouveau design.
