I just love rings with a sentimental inscription. Here is a beautifully made three stone Opal ring with wonderful scroll work in 18 K gold. Add to this the four well matched Rose Cut Diamond accents and the inscription 'Bertha from Jack' and you have a iconic vintage ring.
The ring has three well matched and firey Opals the center is @ 0.50 CT and the two side Opals are > 0.25 CT each. The Diamonds are well matched and @0.20 CT TW measured in mount.
The ring is size 6.5, you could theoretically size the ring, but would you want to disrupt the sentimental inscription? The ring weighs 3.1 grams and in excellent estate condition.
