This is a nice shiny ring, ...I totally defaced  in one day at my bricklaying job.
There is no such thing as a scratch proof ring, maybe Tungsten Carbide which I haven't tried.
The size was good,  and its a bit of a bulky ring, the shipping was fast.
When this ring comes in contact with other metal, brick, sand it will scratch.
I will say that this is a great deal for the price. Keep it off the construction site and all will be fine.
Highly Recommended.
