How can I tell if red coral is real?

There are several different methods available to test if your red coral is authentic. Red coral beads should be smooth to the touch, not rough, even when examined up close. Another easy test is to drop them in a glass of milk and see if the milk changes to a red color. If the milk turns red, then your red coral is the real deal. Since imitation red coral is often made of glass, you can also give it a tap and see if it feels like glass.
