Vintage 14K yellow gold Brutalist brooch/pendant by Karbra, featuring a bezel set black opal measuring 14.75 x 10.5 mm, with strong play of blue, green and red color, in an asymmetrical setting, surrounded by 12 round prong set diamonds and 38 round diamonds in applied white gold bars with milgrain details, diamonds weighing approx. 1.00 ctw, 2 in. W, 19.4 grams

Additional comments added on 9/19/23: Overall good condition, with one tiny chip to one diamond. Given the constraints of the bezel setting we are unable to see the profile to determine if it is a single or doublet. However, the back is not black and some fire can be seen through the back Unless stated in a laboratory report, gemstone and diamond color, clarity, and carat weight are approximate because stones are mounted at the time of evaluation
