Every day is mother’s day at the 72-year-old McCary’s Jewelers When Miles Thomas graduated from Louisiana State University with a degree in business last year, he knew exactly where he wanted to take his newfound education: McCary’s Jewelers, his family’s fine ­jewelry store in Shreveport, La., which was founded by his great-grandfather, James McCary, in 1941. “The opportunity was presented to me to join the business and it felt dumb not to take it,” says Miles, who works with his grandfather, owner R.L. McCary, his mother, jeweler Lynn McCary Thomas, and his uncle, bench jeweler David McCary. Miles had worked summers in the shop—which boasts six bench jewelers and extensive appraisal and custom design services—throughout high school and college. Which could explain why becoming “100 percent committed” to the family business postgraduation felt relatively effortless.
