The details
A round blue aquamarine sits at the center of this knot birthstone ring in solid yellow gold, a bright pop of sea color against a warm metal. The aquamarine is natural and heat-treated, with a clear, cool tone. The yellow gold has a polished finish that gives the interwoven knot a soft glow. Its open back lets light reach the stone, and the band tapers so it feels slim where it sits against the hand. You can wear it with a white shirt and denim, or with a dark dress for an evening out. A thoughtful pick for anyone born in March.
