I bought this necklace years ago (at least two, maybe even three) and I wear it everyday.
I love Celtic Knots and this is just perfect.  It's a little thin but it has been around my neck nearly every day since I've purchased it and it's held up nicely.
There are no scratches, no chips, no bending, no discoloration.
It's seen rain, snow, sweat, sunshine, and pool water over the years and I've even forgotten to take it off before bed a time or two.
I still have the original chain; it has not knotted or broken.
I will be very sad if I ever lose my everyday necklace and hope I'll be able to get another just like it.
