K18 Classic Oval Ring / 4.4mm
K18 Classic Oval Ring / 4.4mm
This simple, comfortable ring can be worn at any age, even as you grow older and become a grandfather or grandmother.
The rounded shape feels gentle when touching someone or something precious and can be worn with confidence in all kinds of everyday situations.
〔Width〕
At 4.4 mm wide, the ring has a much stronger presence and a more casual impression. As the width increases, so does its height, so it is more likely to touch the adjacent finger when you make a fist. However, the increased amount of material gives the ring a substantial gold weight and feel. It is also durable enough to withstand many years of wear, and its durability is less affected by resizing, making this a width you can enjoy for a long time.
〔Materials〕
Choose from four types.
18-karat yellow gold
18-karat white gold
Two-tone (more yellow gold)
Two-tone (more white gold)
We use 18-karat gold, which is less likely to cause allergies, is resistant to oxidation, and is easy to care for.
Yellow gold is hard and resistant to scratches, while white gold tends to scratch slightly more easily, similarly to platinum.
〔Finish〕
“Matte”
“Mirror”
With daily wear, fine scratches develop, and friction against clothing and other surfaces eventually gives both finishes a subdued, lustrous sheen.
