Karagosian & Sons Jewelers, Sylvan Lake

Sibling trio Tim, David, and Harry Jr. oversees Karagosian Jewelers' sparkling empire, maintaining a tradition of knowledgeable gem dealing set by their parents—who began the then-small jewelry business in their Oakland County home in 1950. Since 1968, the current Orchard Lake Road location has expanded three times to accommodate an ever-expanding hoard of designer jewels and constant bouts of brotherly horseplay. Beyond a sizeable inventory, the Karagosians and their staff strive to outclass other jewelry retailers by stamping their direct-from-Belgium diamonds with a guarantee to beat any competitor's price. Personalized customer service includes fiancé-jeweler collaborations that yield custom engagement rings, and the store's GIA-certified gemologist Tim Karagosian can explain various cuts and carats and suggest hip baby names such as Ruby and That One
