Rubies: July’s Birthstone
Rubies are one of the four precious gemstones along with emeralds, sapphires, and diamonds. Rubies get their name from the latin word for red; ruber. The stones come in an array of red colors, ranging from the most expensive vibrant red called “pigeon blood” to light hues of pink. Commonly, rubies are heat treated at temperatures of approximately 3300°F to improve their color, remove purple tinge, blue patches and silk.
In addition to color, a ruby’s quality is determined by its clarity, carat (weight), and cut. Rubies are mined throughout the world, most notably from Burma, Pakistan, Brazil, Columbia, India, Afghanistan, and a few select other countries.
