Rubies light the ruby birthstone jewelry in our birth stone eternity jewelry collection, featuring the summer bright hue of the blazing scarlet July birthstone. The radiant July birth stones were quite favored in ancient times & the Middle Ages, as people then believed they could protect the wearer from harm, and darkened in colour when threats approached. The jewel showcased in a July band forms from the same minerals as the sapphire, & both are regularly found together in the same mineral deposits.
