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.
※ During the pre-order period, customers who purchase a total of ¥65,000 (tax included) or more, including any Nexus items, will receive a special Nexus original brooch as a gift.

Resizing at the time of purchase
For rings over ¥33,000 (tax included)
We offer complimentary resizing within ±3 sizes from the size in stock. If you wish to have your ring resized, please proceed to the purchase screen of the item and enter the desired size in the remarks form in the shopping cart. Production period: about 4 weeks
For rings under ¥33,000 (tax included)
We do not accept resizing from stock items. Please contact us using the inquiry form and we will make a custom order in the desired size. Production period: about 5 weeks
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.
