Brittny Gastineau—the daughter of former New York Jets star Mark Gastineau—is more than a beautiful face. She’s a model, gal pal to Kim Kardashian and codesigner with her mother, Lisa, of the costume- and fine-jewelry line Trés Glam by Lisa & Brittny Gastineau. Launched in 2005, Trés Glam fuses tradition with contemporary edge in a collection comprised of sterling-silver and 18k gold bracelets, rings, earrings, necklaces and ankle bracelets mixed with an array of colored diamonds and other gemstones. The anti-envy eye—a symbol said to protect and ward off others’ ill intentions—is the trademark of the brand, while many of the other pieces celebrate elements of nature, featuring crescent moons, stars, snakes, octopi and more. We asked this New Yorker- turned-Angeleno to let it all spill out and tell us what she never leaves home without.
