5 /5 S Noh: I had an amazing experience working with Danielle at Bella Cosa Jewelers to purchase my dream diamond studs. I had already done a ton of research online and shopped around the Chicagoland area but Bella Cosa ultimately had the highest quality, well matched, GIA certified diamonds for the most reasonable price. I asked Danielle a million questions and visited the store multiple times before making my decision. Danielle was super welcoming, patient and informative from start to finish. I highly recommend Bella Cosa for your next special heirloom quality piece of jewelry!
