You're welcome. I would explore working with another SA.
Yes, it is better to buy in person and not online especially with stones. If you had 5 in front of you, obviously you would pick the best one for you. Otherwise with an online purchase, someone is just fulfilling your request and grabbing the 1st one they see. I am based on the West Coast and the Vancouver store is the one I shop at. I believe some VCA are sold at the Birks store? Tbh, I haven't thought of shopping at Birks though. Just a thought.
