2025 Collection "Nexus – Connection –" K18 Yellow Gold Necklace. "I am more than just myself." This design expresses the idea that a single, small point—one's self—is interconnected with everything else, forming a continuous, circular shape. The necklace features a complex, undulating organic form that reveals a multitude of expressions depending on the viewing angle. A single melee diamond, set within the flowing connections, subtly sparkles against the soft, semi-matte finish of the yellow gold. With a simple yet three-dimensional structure, this piece exudes understated individuality. Its lightweight, comfortable fit makes it suitable for everyday wear, effortlessly complementing any outfit. A perfect gift for a loved one, this necklace carries both elegance and meaning.

Selecting your ring size

We recommend choosing a size that you can comfortably wear without feeling pressure or tightness when you make a fist, and without discomfort between adjacent fingers.

For wide rings of 6.0 mm or more
Compared to the number measured with a typical ring gauge, a wide width ring may feel a little tight to wear due to its large surface area. When considering a wide ring, we recommend that you choose a slightly looser size than you usually wear, 1 to 1.5 sizes up.

Please note that some rings cannot be resized due to their design.
Please check the details on each product page.
