Celebrate your loved ones with this stylish mother's stackable disc pendant. Personalize by choosing the birthstone of your choice and by engraving each disc with names or any special sentiment of your choice. 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.
