Is my K Ring scratch-resistant?

Is my K Ring scratch-resistant?

K Ring’s outer shell is made from zirconia ceramic (ZrO2), which is extremely hard and scratch-resistant.

It is significantly harder and more scratch-resistant than traditional metal jewellery – even that made of titanium. However, K Ring can still be damaged if dropped on a hard surface, or if a significant force is applied to it.

The table below provides context for K Ring’s scratch-resistance by showing where other common jewellery substances sit alongside zirconia ceramic on the Mohs scale of hardness:

Material
Hardness
Gold and silver
2.5 – 3
Steel
4 – 4.5
Titanium
6
Zirconia ceramic
8.5
Corundum (rubies and sapphires)
9
Diamond
10

K Ring can easily be scratched by diamond rings or diamond-coated nail files or emery boards, so they must be kept separate at all times. We recommend that you do not wear your K Ring during nail care.
