• Lightly rinse coral in warm water and lay on a paper towel. If you notice any color bleeding on the towel after a few minutes, you can bet it’s dyed.
• Test a small spot near the hole of one of the beads or branches with a cotton swab and finger nail polish remover to see if any dye comes off.
• Check where beads may have rubbed together exposing a different color;
• Check the color of the string, as it could have been dyed the same time as the beads.

NOTE:  Dyed coral is A-OK, as long as you know that when you are buying it.
