REGENCY brooch autumn tones, green, topaz, shimmery gold and AB, art glass shops stones
Rare and lovely LARGE brooch, signed REGENCY on the back, see photos.
Leaf-shaped is what I would call it..... and chock full of autumn colours.
Fabulous art glass stones, please see photos.
The main colour is green, 6 sparkling peridot stones, navettes and marquise. Then topaz and shimmery gold stones, navettes, marquises and baguettes, so unusual. 10 fabulous greeny gold moulded art glass stones crown this motley assortment of beauty. So luscious and rich and all prongset Swarovskis.
The metal is goldtone, a vintage old gold and in pristine condition.
The pinback is long and sturdy, the rollover clasp nice and tight.
9 cm x 5 cm, 3.54" x 1.97"
There is a slight curve to the design, just like a leaf.
An excellent piece for your REGENCY collection. A rare colour combination
