Jennifer Meyer started her eponymous jewelry line in 2005 and it’s been beloved by celebs ever since. Creating timeless, elegant pieces with unexpected details, this 18k gold, opal, and diamond necklace exemplifies her distinct style. With a 2.70-carat heart-shaped opal surrounded by 0.48-carats of pave diamonds, it’s whimsical and modern. (Added bonus: opal is said to stimulate creativity.)
