A one-of-a-kind necklace from the "Plump" series, inspired by the image of a single, full bud gently enveloping and protecting a gemstone, set here 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 cannot be defined as any single hue. Like light reaching the depths of the sea, the three colors gently respond to each other, shifting in expression; their transience evokes a subtle sense of openness within the heart. The matte K18 yellow gold setting, refined with delicate line engraving, gently follows the contours of the well-proportioned round-cut stone. Crafted as a necklace that conveys both understated radiance and meticulous craftsmanship. Tanzanite, also known as the birthstone of December, makes this piece a thoughtful talisman for those born in December.
