So, after years of breaking up and then making up, you've decided she's the girl for you. Now you must find that sparkling diamond engagement ring that is gonna make her say, "Hell, yeah!" We suggest you take a trip to the Seybold Building in downtown Miami, where more than 280 jewelers are ready to help you make sure you don't mess up and come home with something that resembles a trinket out of a Cracker Jack box. Built by Miami pioneer John William Gottloeb Seybold in 1914, the building has entrances on Flagler and First streets. Once inside, you'll have to squint a bit to overcome all the glistening baubles on display. The Seybold Building is the second-largest jewelry building in the United States. You will find an unparalleled selection of diamond rings where jewelers value quality over quantity. For more than 30 years, millions of people have turned to the jewelers inside the Seybold Building to help them find the perfect gifts for the significant people in their lives. Or maybe you feel like buying the diamond and having the ring made. Well, amid the 200 tiny workshops and boutiques, you will find spaces occupied by diamond cutters, gem setters, and gold dealers who can help you make a unique ring. For example, you could visit diamond dealer H&Y Diamonds on the tenth floor, where you can find rough and cut rocks from across the globe. After selecting a fantastic stone, take the elevator one floor down, where setters such as Ernesto Ercilla will charge you $2.50 to mount small stones or from $25 to $35 to set a two-carat stone. And if you don't want the hassle of searching for a parking spot, there's valet service. The Seybold is open Monday through Saturday from 9:30 a.m. to 5:30 p.m.
