Hello all! I really need some recommendations from anyone who has purchased any of Chanel's Agate jewelry. Specifically, I believe the camelia collection contains a lot of agate. I have read that agate is very delicate and prone to cracks and chips, especially after it has been cut. Does anyone own Chanel jewelry with agate and what has been your experience with its durability? I'm attaching a pic from the Chanel website to show you the particular ring I'm contemplating Thanks so much in advance!
