A one-of-a-kind ring crafted with a mermaid tanzanite. Rare pieces in which light purple, blue, and green overlap are called "mermaid tanzanite." Unlike typical tanzanite, known for its deep blue, this stone quietly unfolds a delicate, clear, multicolored shimmer that resists being defined as any single hue. Like light piercing the depths of the ocean, the three colors gently respond to one another, shifting in expression; the transience of this change evokes a quiet openness within the heart. The K18 yellow gold setting and band that hold the horizontally elongated cushion-cut stone feature an irregular hammered texture. A special ring that adds a quiet elegance to the hand. Tanzanite, also known as the birthstone of December, makes this piece a meaningful talisman and a thoughtful gift for those born in December.
