Here is another handsome Opal ring in 14 K yellow gold. It is size 6 and could be sized by your local jeweler if needed. It weighs 4.4 grams and the stone is 1/2" by 3/8" so @4 CT on my guide. It is in excellent estate condition and comes from New Haven County Connecticut. I love the variety of colors in Opals and the @20 side Diamonds draw the eye and add sparkle.
