K18 Classic Oval Ring / 3.2mm
K18 Classic Oval Ring / 3.2mm
This simple, comfortable ring can be worn at any age—even as you grow older—and remains suitable for you as you become a grandfather or grandmother.
The rounded shape feels gentle even when touching someone or something important, and can be worn安心fully in all kinds of everyday situations.
〔Width〕
The 3.2 mm width is durable and less prone to deformation, making it recommended for those who want to wear it at all times.
Its low-profile design minimizes interference with adjacent fingers, making it comfortable to wear even continuously.
〔Materials〕
Choose from four types.
18K yellow gold
18K white gold
Two-tone (more yellow gold)
Two-tone (more white gold)
We use 18K gold, which is less likely to cause allergies, resists oxidation, and is easy to care for.
Yellow gold is hard and resistant to scratches, while white gold tends to scratch somewhat more easily, similar to platinum.
〔Finish〕
“Matte”
“Mirror”
With daily wear, fine scratches develop, and friction against clothing and other items eventually gives both finishes a subdued luster.
