Vintage Carved Opal cameo. The lady in the cameo faces left, has ornate hair and a lovely undamaged profile. The opal is 75% transparent with a few patches of translucence. The primary color flashes of the Opal are :Yellow, green , blue, violet. The mounting of the cameo is 18 karat yellow gold with six round brilliant diamonds in 18 karat white gold heads. The diamonds average 2.35 mm each and have an estimated total diamond weight of .27 ctw of diamonds. These diamonds are G/H in color and SI1/SI2 in clarity.As Cameos are hard to figure carat weight, we removed and weighed. The exact weight of the opal is 31.22 cts. Oddly both the hinged bail and the pin set are 14 karat gold. In normal light they seem the same color as the 18 karat gold mounting, but under a gemscope the color difference is obvious which is why I acid tested separately. Circa 1950. I am a Graduate Gemologist and a retired Jewelry store owner (18 years) and my husband is my jeweler. Shipping is $9.50 USPS priority mail, signature required. 2 week return.
