This iconic Open Hearts by Jane Seymour® design couple's necklace features a horse shoe for good luck for you and your loved one accentuated by the birthstones of your choice. You may personalize by engraving that special sentiment. Most natural gemstones pictured have been subject to an enhancement process or treatment (e.g. heating, oiling, diffusion, waxing, etc.), which may not be permanent and may require special care. Generally, most treated gemstone jewelry should only be gently cleaned by rinsing in warm water and dried with a soft cloth. Please refer to the FAQ section below for more information about gemstone enhancements and special care recommendations.
