This intricately designed and crafted vintage-style ring features a raised, polished Moonstone circle, countersunk in an engaging, filigree openwork, Sterling Silver shoulder setting, on a D-shaped band. Like a piece of solidified moonlight, this Moonstone gem — the alternative birthstone for June — has a shimmering luminescence which emanates in a luna glow. (This is called adulaescence, after an early Moonstone mine site at Mt Adula, Switzerland).
