Occasional cleaning and mindful wear are advisable for this pendant, and that is realistic maintenance for a natural stone. Shungite is carbon-rich and softer than many gemstones, so gentle handling is best. Wipe the stone with a soft, slightly damp cloth to remove dust, skin oils, and any loose dark particles, then dry it thoroughly with a separate dry cloth. Do not soak the stone in water for long periods, and avoid harsh cleaning agents, alcohol, or abrasive pads, as these can damage the stone surface or the thread.
Because the pendant hangs on a thread, the thread is the part most likely to wear out over time. Check the knot and the cord periodically, especially if you wear the pendant daily. If the thread begins to fray or the knot loosens, replace the cord before the stone is lost. This is ordinary maintenance, not a sign of poor quality.
For storage, keep the pendant in a dry place, preferably in a small pouch or a separate compartment of a jewelry box. Natural stones can scratch softer materials and can also be scratched by harder jewelry, so storing this pendant separately protects both the stone and your other pieces. Keep it away from constant humidity, such as a bathroom shelf, to reduce moisture-related dark marks and to keep the thread from weakening. With this simple routine, the pendant should remain neat and pleasant to wear for a long time.
