Take a piece of a fabric, striped red and white, and draw the stone to be tested over the colors. If it is an imitation, the colors will be seen through it, while a diamond will not allow them to be seen.
A genuine diamond, rubbed on wood or metal, after having been previously exposed to the light of the electric arc, becomes phosphorescent in darkness, which does not occur with imitations.
Heat the stone to be tested, after giving it a coating of borax, and let it fall into cold water. A diamond will undergo the test without the slightest damage; the glass will be broken in pieces.
Finally, try with the fingers to crush an imitation and a genuine diamond between two coins, and you will soon see the difference.
