How To Care Your Gem Stones
At Gemological Analysis Centre (GAC), we believe that taking proper care of your gemstones and studded jewelry is as crucial as the initial purchase. A well-cared-for gem will retain its brilliance, color, and value for generations to come. Here are some key points to consider for optimal gem care:
Gem Care
Always pick up your jewelry by the edges, avoiding contact with the gemstone surface to prevent oils or dirt from affecting its brilliance
Cleaning
Use mild soap and water with a soft brush to clean most gemstones. However, some gems like pearls and opals require special care. Always consult a professional before attempting to clean any valuable piece
Storage
Store each piece of jewelry separately in soft pouches to prevent scratching or friction damage. Avoid exposing gemstones to extreme temperatures or direct sunlight
Inspections
Periodic professional inspections can identify any loose settings or minor damages before they become significant problems
Chemical Exposure
Keep your gemstones away from harsh chemicals, including household cleaners and chlorine, as they can erode the metal settings and affect the gem's color
Specialized Care
Certain gemstones like emeralds and pearls are sensitive to oils and moisture. Always consult with experts about the best practices for individual gem types
