Cultured pearls are precious jewels and should be treated as such. Nacre gives pearls the rainbow of colors and luster that makes these gemstones so treasured, but its delicate nature also makes pearls particularly susceptible to damage. For this reason you should be extra careful with your cultured pearl jewelry.
Never ultrasonic or steam clean.
Avoid heat. Restring often (once a year). Wipe off with a soft, damp cloth after each wearing. Do not submerse or soak in any liquid. Store away from other jewelry items. Put on last, take off first to avoid direct contact with perfume and hairspray.
Hardness (Scratch Resistance)
2 1/2 - 4 on the Moh's Scale
Toughness (Chip & Crack Resistance)
Usually good unless the outer layers have surface imperfections.
Stability (To Heat, Light, Chemicals)
Avoid any exposure to prolonged heat including intense light sources. Generally stable to light. Avoid chemicals, all acids, perspiration, skin oils, perfume, and hairspray (alcohol-based).
Cultured Pearl Care Tips
- Apply cosmetics, hair sprays and perfume before putting on any pearl jewelry. When you remove the jewelry, wipe it carefully with a soft cloth to remove any traces of these substances.
- You can also wash your pearl jewelry with mild soap and water. Do not clean cultured pearls with any chemicals, abrasives or solvents. These substances can damage your pearls.
- Do not toss your cultured pearl jewelry carelessly into a purse, bag or jewel box. A pearl's surface is soft and can be scratched by hard metal edges or by the harder gemstones of other jewelry pieces.
- Place cultured pearl jewelry in a chamois bag or wrap them in tissue when putting them away.
- Cosmetics, perspiration, oils and ordinary wear weaken and stretch the threads on which the pearls are strung. Bring your pearls back to your jeweler for restringing once a year. Make certain the pearls are strung with a knot between each pearl. This will prevent loss of pearls if the string should break.
