Get Educated - Research the subject of buying diamonds, in exactly the same way you would if you were buying a car. In the dimly lit beam of a torch, a handful of Jewelry, stuffed into a pocket, stops them searching any further, and they leave without any more damage. So OCCASIONALLY buy that antique looking string of pearls (which we know are glass beads) from the local Op shop or Charity Church Bazaar, and salt it into your 'attractive' Junk items in the Jewelry Box on the Dresser.
