Gemstone Care — Be Gentle With Your Pearls

If June is your birth month, and you love pearls (as I hope you do), treat them gently. Pearls are not as rugged as their crystal mineral counterparts. Made up of layers of tiny crystals of aragonite, they’ll scratch, fracture, discolor, and dissolve if not treated with loving kindness.

  • Never wear pearls when exercising; perspiration can attack them. They don’t like household chemicals, either. Never wear them swimming in a pool. (If Cleopatra’s pearls dissolved in wine, just think what chlorine can do to them.)
  • Don’t wear them if you’re doing work where they’ll come into sharp contact with hard surfaces. A bracelet constantly thwacking on a desk or filing cabinet can only harm the pearls.
  • Put them on after you’ve applied your makeup and perfume. Wipe them down with a soft cloth after you take them off to remove the pigments and alcohol that can damage them.
  • Store them in a soft cloth bag to protect them from scratching by the other jewelry in your box (drawer, suitcase, steamer trunk).
  • Give them a gentle bath, periodically, if you wear them often, and lay them out to dry thoroughly. Do not hang pearl strands up—the string can stretch.
  • If you wear pearl strands frequently, inspect them regularly, and have them restrung periodically.
  • Knots between the pearls protect them from rubbing against each other at the fragile drill hole. Knotting also prevents loss should the strand break. You’ll only be scrambling around on the airport floor looking for one pearl, not dozens. Because Mrs. Murphy says that if your pearl strand is going to break, it’ll break at the most inconvenient place and time possible.
