Marquis Jewelers (416) 964-7773 is located on 2 Bloor Street just west of Yonge/Bloor (enter the strip mall near Swarovsky and walk towards the back of the mall). Don't be put off by the cheesy decor and some of the jewelry on display, these people make amazing jewelry. They actually do most of the major repairs for Birks and in some cases make some of their pieces. I came here to get the diamonds on my wedding band tightened and I couldn't believe a: how reasonable it was ($25 - very cheap compared to Birks) and b: how incredible my ring looked after! They polish and buff all of their repairs and that lasts a long time. I also bought my ring cleaner here, again, cheaper and better quality than the jewelry sparkle from Birks. If you want to buy any type of jewelry or get something custom made, talk to the owner, Socrates. His prices are unbeatable and the quality is top-notch. This is a little secret most people don't know about but if you live in Toronto or are ever here for a visit and thinking about buying some jewelry, go here!
