A beautiful engagement ring hangs together with an engravable heart in this meaningful necklace. Engrave the heart with a name, date or special message! A spring ring clasp secures the 18-inch rope chain. 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.
