Figure anybody can sell you some shiny gewgaws. But what do you do if the jeweled piece you thought was perfect for your sweetie turns out to get shrugs and winces when you hand it to the recipient? No need for psychodrama over whose taste is better. Take it for a makeover to Ralph Austin Jewelers, an unprepossessing little shop in the Skillman Shopping Center in East Dallas. They'll take that ring (or bracelet or necklace) and modify it, or melt it down, make a new design, 3-D print a model, create a mold, cast it anew and, using your gold and stones, give your sweet thang the hunk of jewelry of his or her dreams. Prices are reasonable. Service is 24-karat friendly. Yep, this place is a gem.
