Care & Collecting

Most damage to gemstones happens at home: the wrong cleaner on a treated emerald, an opal left to dry out, a soft stone tossed in a drawer with harder ones. This collection covers safe cleaning stone by stone, sensible storage, and starting a mineral collection without expensive mistakes. Care advice here is always stone-specific and treatment-aware, because it has to be — an untreated sapphire shrugs off an ultrasonic cleaner while a fracture-filled emerald can be ruined by one. We tell you which is which, and we never frame collecting as an investment strategy.
