Earrings, Genuine Red Ruby & cz, drop chandelier earrings

Dangle earrings, 3 genuine rubies on each earring. 6 total rubies.  white cubic zirconia accent stones set in silver. These look amazing on.

How can you tell if a stone is really a ruby? Natural rubies glow under black light. See the second picture where the rubies are glowing under the black light. Can provide black lite pick if requested. :)
