This unique and brightly colored ring features a center stone which electronically tests as glass. The color is a rich, deep turquoise with fun mermaid vibes and very much a stand-out piece. Color is quite hard to capture properly on film - it is more vibrant and eye-catching in person.
Band is marked for 10k and unknown maker's mark. Shoulders have slight detailing reminiscent of mid-century styling (1940-1950s).
Total weight is 1.38g. Size is slightly larger than 5.5 but band is just out of round, so fit would likely be 5.5-5.75 - could be sized within reason.
There is some wear to the stone facets on loupe inspection but good overall shape for age. Band is slightly out of round and gold is unpolished, so may have traces of patina.
