These are single stud earrings featuring a teardrop-briolette-cut moss aquamarine. This piece has a high concentration of moss (titanium iron inclusions), resulting in a black color rather than blue. Some areas exhibit a schiller effect. Please enjoy the natural imperfections of the gemstone as part of its unique character. The hook earring findings, jump rings, and artistic wire are made of surgical stainless steel. Screw-back earrings (with silicone covers) are available for an additional ¥150.
