Price: 221000.0 JPY
Availability: OutOfStock

A one-of-a-kind necklace featuring a cabochon-cut clear diamond with a domed surface. Imparting this gentle curvature to the hardest material on Earth requires extremely precise polishing techniques. Expert craftsmanship renders the light within the stone three-dimensionally, creating an expression reminiscent of dripping water. The design is simple, yet subtle undulations along the outline allow the stone's presence to emerge naturally. Milky ice-colored diamonds surrounding the main stone add a soft cohesion and poised brilliance to the piece. A necklace that quietly accompanies daily life while imparting a refined presence at the neckline.

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.
