I have been surprised how my base model has taken a beating from me and came out unscathed. Case in point, over the holidays while visiting family I was tooling through the kitchen and WHAM the crystal slams into the handle of a cast iron skillet. so hard that my first reaction was to grab my wrist and as i looked down to my shock the crystal was not broken, cracked, scratched or blemished. That was the worst it has been, so i can understand its imperviousness to the lighter stuff i have put it through.
