* Keep your platinum jewelry away from other jewelries to prevent the scratches on the jewelries * Keep your platinum jewelry and other precious items at a safe place. * Clean your platinum jewelry periodically. This will ensure its fine appearance and will help it last. * Clean platinum in the same way you clean other fine jewelry - using a pre-packaged jewelry cleaner or by soaking it in a mild solution of 50% ammonia and 50% warm water and then gently rubbing it with a soft cloth. Note that harsh chemicals such as ammonia should not be used on gemstones other than diamonds because it may damage them - consult a jewelry professional in-person for specific guidance in this matter as it applies to specific jewelry items. * Have your platinum jewelry polished and cleaned by a qualified jeweler twice a year. * Take your platinum jewelry to a qualified jeweler twice per year for inspection. Only allow a trained professional jeweler to work on your platinum jewelry! Adjustments, resizing, polishing and cleaning of your platinum jewelry should be provided by a trained bench jeweler. We can't tell you how many times we have repaired platinum jewelry that has been resized using white gold by some jeweler who should never have been working on a platinum jewelry item to begin with! * Be aware that over time platinum develops a natural patina that many people prefer over the "just polished" appearance of platinum. When this happens to your platinum jewelry you may take it to a qualified jeweler and have the item polished for that "high gloss" look or simply ask them not to remove the patina if that is your preference.
