It looks delicate but not. I've been using it since I got it and so far it's pretty strong for a daily use. I got Bracelet and necklace and loved it..

I gave it to my Niece for her 24th birthday and she loves it. Professionally she is an actuary, this symbol is a mathematical sign and represents my love....no beginning and no end. She loves it...!
