July Birthstone: Ruby

The July birthstone is ruby, the red variety of the mineral corundum. Coloured by chromium, ruby is 9 on the Mohs scale, second only to diamond, so it is made to be worn every day.

Ruby colour runs from pinkish red to deep purplish red; a vivid, saturated red is the most prized. It is the traditional gift for a 40th anniversary, and in Jyotish ruby (manik) is traditionally associated with the Sun.

For July birthstone jewelry we offer natural ruby and diamond halo stud earrings in solid 18K yellow, white or rose gold, ruby flower halo studs, ruby spike ball studs, the Cancer zodiac necklace with a ruby at its brightest star, and natural loose Mozambique rubies, including a 3.15 ct oval and a matched pair for earrings.
