ThisÂ Aquamarine Branch Ring is an enchanted ring. Its sterling silver band is cast by jewelry artist Nancy Nelson from a handcrafted mold made from green twig found in the ancient woods of West Virginia. Rather than the hard formality of a cut stone, it holds a rough-hewn nugget of aquamarine. A gemstone long believed to promote good luck and harmony, it seems to have an otherworldly glow when it catches the light. $70. Buy here.
