AmaSwiss Jewellery Inc

My fiancé and I bought our engagement ring at the AMA Swiss in Calgary, where we live — it’s a beautiful piece, unlike the quintessential diamond ring. We are new to buying jewellery like this and all we knew was that we wanted something we’d love and for a decent price; got both.
Good points — 1. Got to take time and look, but you can find pieces here that you might not find elsewhere; they don’t make large volumes of the same piece, 2. Got ours at a very decent price — we don’t believe in the «3 times your monthly salary”-bull shit :). Our ring needed resizing, and it returned pretty quickly.
Unfortunately, we didn’t have a very good time dealing with the store owner/​manager, post-​purchase. When we bought the ring, we were told the diamonds were of higher quality* than originally claimed and when it returned from sizing, we were told it was rhodium-​polished «again”** (I got white gold). First impression — satisfactory. I was extremely careful (I know how to treat diamonds/​white gold from owning similar products). When I removed my ring THAT same night, I noticed one specific section of the ring looked like it was losing polish and turning yellow gold; it also had two separate dents and I believe this was exactly the part that was resized to fit my finger. I called the manager the next day to ask her what this was and she told me that because her father made it a long time ago it could be losing polish. Confusing, because we thought it was re-​polished… so we visited her and showed her the ring — she claimed that because I am a woman, I notice things that might not actually be there (pissed my fiancé off but I found it amusing that she would say something silly like that in her defense). She also claimed that she didn’t see anything wrong with the ring. Good thing is that she still sent it to get re-​polished.
We got the ring back a second time. Looked alright; we drove home, and lo and behold, that exact same spot started turning white gold only a couple of hours after wearing the ring (NOTE ** in previous para). Again, I was extremely careful but we didn’t want to deal with her again, so we decided to get it polished elsewhere. TO OUR SURPRISE, when we looked at the ring closely, we found one of the smaller diamonds missing. When we went over to the store and showed it to the lady, she basically told us it was our fault because we didn’t inform her immediately. I understand why she did this — I explained to her that we found this missing piece after we looked closely at home and kept it aside, while we were gone for the weekend. She was closed the Monday when we got back, hence the delay. When asked, she admitted to not having checked the ring after it got back from the second re-​polishing, so I was extremely surprised when she accused us. Again, good thing here was that she sent the ring to the Toronto wing, and when it got back she told me that «some of the diamonds were of lower quality and were replaced» (DEFINITELY NOTE * in previous para).
I can tell you this much — after this ring went to Toronto and came back, a magician worked his charm on it. I don’t know if the diamonds were actually replaced with «higher» quality ones, but they looked good and we haven’t had issues so far. MAIN point here is that the dent and the yellow colouring of my ring has stopped happening completely. I am almost entirely certain they completely re-​did that section and sent it back to us.
We are huge supporters of mom-​and-​pop stores, but after this experience, I’m not so sure we should be so naïve. We ended up having to deal with someone who made sure we knew how troublesome we were for NO fault of our own.
