Fortunately I haven’t had too many issues with quality at time of purchase, but I’ve had a lot of trouble with repairs/engraving!! It started with a holiday pendant that got sent out for engraving and came back with the wrong size initials. Then more recently, I snapped the post on a pair of vintage Alhambra earrings (my own fault for being too rough) and when I got them back from the workshop they’d been repaired with a shorter post that didn’t match and was angled funny. I sent them back for repair, and the post issue was fixed, but the part at the bottom that the lever back attaches to (not sure what it’s called) was bent a little. At this point I decided they couldn’t handle another trip to the workshop so I just bought another pair—it had been a year and I was tired of not having them in my wardrobe. I snapped the post on another pair of earrings by fiddling with them because I apparently cannot be trusted to learn my lesson the first time (and also didn’t want to have to send them to the workshop for adjustment) and I am DREADING sending them off for repair—I’m thinking of just buying another pair of those too.
