Vintage key brooch, gold tone, white and black glass pearls, red and green rhinestones and turquoise glass cabochons, old presentation box

Beautiful vintage key brooch, featuring a turquoise blue glass cabochons, different shaped red, green and clear rhinestones and an interesting trefoil design in white and silvery grey glass pearls. The brooch has a bright gold tone base and settings and is beautifully and delicately designed and constructed.

It was acquired in its own vintage, hinged presentation box as pictured, which has a black outer finish and a swivelling hook clasp. I was surprised to find this piece unsigned and not traceable to any of the patent applications for top quality costume jewellery companies like Trifari or Coro. I think the patent or design plan is probably out there somewhere, but I have yet to find it! The brooch fastens with a long pin and secure roll-over clasp and is in very good vintage condition - please examine the pictures carefully for a full condition report.
