c. 1880, 14K white gold crown brooch featuring old mine and old European cut diamonds weighing approx. 1.25 ctw, 1.75 in. W, 12.8 grams

Additional comments added on January 21, 2022: It's possible that one diamond is missing from the bottom center, but there is no evidence that there was a diamond setting there. The rose cut diamonds on the sides are just very eye clean 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
