K18 Classic Ovel Ring / 5.0mm
K18 Classic Ovel Ring / 5.0mm
This simple, comfortable ring can be worn at any age, even after growing old together and becoming grandparents.
The rounded shape feels gentle even when touching someone or something precious, making it comfortable to wear in any everyday situation.
〔Width〕
At 5.0 mm thick, the ring has a much stronger presence and a casual look. As the thickness increases, so does the height, so it is more likely to touch the adjacent finger when you make a fist. However, the greater mass of the material gives the ring a substantial, weighty feel, and it is durable enough to withstand many years of wear. It is also a thickness that can be enjoyed for a long time, with little reduction in durability from resizing.
〔Materials〕
Choose from four types.
18K yellow gold
18K white gold
Two-tone (more yellow gold)
Two-tone (more white gold)
Made with 18K gold, which is less likely to cause allergies, it is resistant to oxidation and 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”
“Polished”
With daily use, fine scratches develop, and friction against clothing and other surfaces eventually gives both finishes a subdued, elegant sheen.
