Both carnelian and jasper are varieties of chalcedony, a form of quartz, and share similar care requirements due to their comparable durability and composition. They rank between 6 and 7 on the Mohs hardness scale, making them reasonably resistant to scratches but still susceptible to damage if not properly cared for.

Here are the essential steps to keep your carnelian and jasper jewelry looking its best:

Cleaning
Warm, soapy water:
• The safest and most effective method for cleaning carnelian and jasper is using warm water and a mild, non-abrasive soap, such as dish detergent.
Soft brush:
• Use a soft-bristled brush (like an old toothbrush) to gently scrub around the gemstone and its settings, where dirt and grime tend to accumulate.
Rinse thoroughly:
• Rinse the jewelry thoroughly under lukewarm running water to remove all soap residue, which can dull the stone's luster.
Dry completely:
• Gently pat the jewelry dry with a soft, lint-free cloth.
Avoid harsh chemicals:
• Never use harsh chemicals like bleach, ammonia, or abrasive cleaners on carnelian or jasper, as they can damage the stone's surface and potentially weaken the setting.
Ultrasonic and steam cleaners:
• It is generally best to avoid ultrasonic and steam cleaners for carnelian and jasper, especially if there are any fractures or inclusions in the stone, notes The Natural Gemstone Company.

Handling and wear
Protect from impacts:
• While relatively tough, carnelian and jasper can chip or crack if struck forcefully, particularly at edges or thin sections.
Remove during activities:
• Take off your jewelry before engaging in strenuous activities, such as sports, gardening, or cleaning, to prevent accidental damage.
Minimize water exposure:
• Although carnelian can withstand brief immersion in water, prolonged exposure, especially to chlorinated or saltwater, can affect the stone and its setting. Jasper, while durable under normal conditions, including water immersion, can still be affected by harsh chemicals.
Avoid harsh chemicals:
• Protect your carnelian and jasper from contact with harsh chemicals found in cleaning products, hairsprays, cosmetics, and perfumes.

Storage
Store separately:
• Store each piece of carnelian and jasper jewelry individually in a soft pouch or a lined jewelry box with compartments to prevent scratches and tangles.
Avoid harder materials:
• Keep carnelian and jasper separated from harder gemstones, like diamonds or sapphires, to avoid scratches.
Cool, dry place:
• Store jewelry in a cool, dry place away from direct sunlight, which can cause fading over time.

By following these care guidelines, you can ensure that your carnelian and jasper jewelry remains beautiful and vibrant for years to come.
