This vintage 14K gold and sardonyx ring is big and bold and a fine example of mid century modern design affirmed by the engraved 1951 date. The sardonyx stone is fabulous and sizable, measuring 11mm by 14mm, and is a gorgeous, rich, carnelian, rusty red color that looks great with the 14K yellow gold setting. The ring is hallmarked 14K and has the date 8 20 51 and the initials J B G in script on the inner band. The ring is a size 10 to 11 and weighs 6.22 grams. This beauty is in great vintage condition with very slight age appropriate wear and it's suitable for a man or woman. Sardonyx is considered a protective stone that imparts optimism, confidence and happiness, and with that, I rest my case.
