July’s Birthstone: Ruby

July Birthstone – Ruby


It doesn’t matter if your astrological sign is Cancer or Leo, if your birthday is in July, then you share the same birthstone…a red ruby. Known as the “King of Gemstones”, the ruby is not only stunningly beautiful but also symbolizes romance, prosperity, generosity and devotion.

What is ruby?

Ruby is the most valuable variety of the corundum mineral species, which also includes sapphire. In its purest form, the mineral corundum is colorless. Trace elements that become part of the mineral’s crystal structure cause variations in its color. Chromium is the trace element that causes ruby’s red, which ranges from an orangy red to a purplish red. The strength of ruby’s red depends on how much chromium is present—the more chromium, the stronger the red color. Chromium can also cause fluorescence, which adds to the intensity of the red color.
