Rubies light up the July birthstone ring in our birth stone eternity bands assortment, accentuating the summer-bright hue of the blazing scarlet July birth stones. The vibrant July band birth stones were quite prized in ancient times and the Middle Ages, because people then believed they would protect the wearer from harm, and darkened in color when danger approached. A ruby July birthstone forms from the same minerals as the sapphire, & both are frequently found side by side in the same mineral deposits.
