K18 Emerald and Diamond Necklace This necklace features a cute clover design. The emerald, though small, is a deep color and surrounded by diamonds, giving it a strong presence. The azuki chain has a slide adjuster, allowing you to adjust the length to your preference. Chain length: 45cm Markings: 0.08/0.09 The exact carat number is unclear. There is no certificate of authenticity. I purchased this at my usual jewelry store, but I was so satisfied with it that I kept it carefully stored away without wearing it. Material: K18 (18 karat gold)
