Fresh, luminous, and quietly modern, these mint green chalcedony rectangles bring a cool, watery glow to any design. Ranging from 12x9mm up to 16x12mm, each pair is thoughtfully matched and finished flat on the back so they sit cleanly against the body or layer beautifully in stacked pieces. Add a dreamy wash of color to necklaces, charms, and layered stacks without overpowering your design.
