Public Displays of Affection

Jennifer Lopez and Marc Anthony

Ever since his June 2004 wedding to Jennifer Lopez, Marc Anthony has been gifting his bride with the platinum-and-diamond Neil Lane designs she borrowed for her walk down the aisle. This 50-carat diamond bracelet, which designer Lane describes as "vintage-inspired, sparkly and gemmy," is one of Anthony's emblems of love.

's Valentine's Day gift to Faith Hill perfectly embodied his wife's easy, feminine style. "Faith loves jewelry with pink stones," says Lorraine Schwartz, who designed the necklace with rose quartz and diamonds. "It's a little funky and a little rock and roll. She can easily wear it everywhere."

Richard Gere and Carey Lowell

As a Valentine's Day gift, Richard Gere chose this ring for his wife of four years, actress Carey Lowell, who celebrated her birthday just three days earlier. "I mounted an 18th-century rose-cut diamond on a modern gold band," says the ring's designer, Renee Lewis.

Samuel L. Jackson and LaTanya Richardson

"They collect jewelry as well as art," says designer Cynthia Bach of Samuel L. Jackson and his wife of 26 years, actress LaTanya Richardson. For Christmas the Oscar-nominated actor gave Richardson one of Bach's most original and striking creations: a tassel necklace, which Bach says, "has the silky feel of fabric, even though it's made of gold."
