1. Clean them regularly: Gemstones can lose their brilliance if they are not cleaned regularly. Use a soft, lint-free cloth to gently wipe away any dirt or dust that may have accumulated on the surface. Make sure to avoid using harsh chemicals or abrasive materials that can damage the gemstone. 2. Avoid exposure to excessive heat: Many gemstones, such as opals and pearls, are sensitive to heat. Avoid exposing them to excessive heat sources, such as direct sunlight, hot surfaces, or even hot water. Quick changes in temperature can also be detrimental, so it's advisable to remove gemstone jewelry before taking a hot shower or going to a sauna. 3. Protect from scratches and impact: Gemstones can get scratched or damaged if they come into contact with other hard materials. Store them separately in individual compartments of a jewelry box or wrap them in soft fabric to prevent scratches. Similarly, be cautious of impact or hard knocks, as they can chip or crack gemstones. 4. Avoid exposure to chemicals: Chemicals can erode or damage certain gemstones, especially those with softer compositions or more delicate properties. Avoid wearing gemstone jewelry while using household cleaning products, swimming in chlorinated water, or applying lotions or perfumes directly onto the gemstone. It's advisable to remove and safely store jewelry before engaging in any activities involving chemicals. 5. Periodic professional re-polishing and restringing: Gems set in jewelry often require professional maintenance. Gemstone jewelry may need re-polishing or restringing to restore their original luster and ensure the settings are secure. Consult a professional jeweler or gemologist to assess and perform any necessary repairs or maintenance. 6. Store properly: When not being worn, store gemstone jewelry in a cool, dry place away from direct sunlight. Exposure to sunlight or prolonged air exposure can cause some gemstones, like amethyst or kunzite, to lose their color over time. While storing, ensure gemstone pieces are not in contact with one another to avoid potential scratching or abrasion. 7. Schedule regular inspections: To maintain the longevity and brilliance of gemstones, schedule regular inspections with a reputable jeweler or gemologist. They can identify any potential issues, recommend necessary repairs or adjustments, and provide professional cleaning to keep your gemstone jewelry in its best condition. Remember, caring for gemstones is unique to each stone's specific properties, as different gemstones have varying levels of hardness and sensitivity. Always refer to individual care instructions provided for specific gemstones, and consult experts for guidance when in doubt.
