Smoky quartz has an average hardness, making it a durable gemstone. It can, however, be sensitive to heat and strong sunlight exposure. To avoid color changes, it is best to keep your smoky quartz away from these elements. To clean smoky quartz, use a soft cloth to wipe away dirt and debris.

Avoid vigorous polishing of your gold-filled jewelry so as not to destroy the gold coating, and never expose it to moisture. Keeping it in a zip-lock bag will prevent moisture and humidity from attacking it.
