K18 Classic Oval Ring / 4.4mm
K18 Classic Oval Ring / 4.4mm
This simple, comfortable ring can be worn at any age, from youth to old age.
Its rounded shape is gentle when touching loved ones or cherished items, making it safe for use in all daily situations.
[Width]
At 4.4mm, the presence of the ring increases significantly, giving it a more casual impression. As the width increases, so does the height, making it more likely to touch adjacent fingers when you clench your hand. However, the increased material mass means you can feel the substantial weight of the gold. This ring also boasts durability that can withstand many years of wear. It's a thickness that will be cherished for a long time, with minimal degradation in durability even with repairs.
〔Material〕
Available in 4 types.
18k Yellow Gold
18k White Gold
Combo (more yellow gold)
Combo (more white gold)
Made with 18k gold, which is less likely to cause allergies, resistant to oxidation, and easy to care for.
Yellow gold is hard and resistant to scratches, while white gold tends to scratch slightly more easily (similar to platinum).
〔Finish〕
"Matte"
"Polished"
With daily use, both finishes will acquire minor scratches and rub against clothing, eventually settling into a subdued luster.
