About the Gemstone

Rubies are some of the most prized gemstones in the world. They are from the same mineral as sapphires (corundum), but the deep red of ruby earned the gem it's own special name. Rubies are sourced from Myanmar, Thailand, and Sri Lanka. They are usually cut in the shapes of round brilliant, emerald, oval brilliant, or cabochon, although other cuts are available as well. Scoring a 9 on the Mohs Hardess Scale, rubies are a very good choice for jewelry and engagement rings.

Ruby Symbolism and Folklore

In early cultures, rubies were believed to hold the power of life because of their blood-like color. Ruby is mentioned in the Bible associated with beauty and wisdom, and in Sanskrit, ruby is called ratnaraj, meaning "king of precious stones". In various cultures, rubies were thought to bring peace and protection to those who carried the gem. Even through the development of Western culture the ruby remained highly valued by the elite and worn to bring health, success, and love.

The name "Ruby" came into use as a girl's name in the 1800s in the United States, Australia, Great Britain, and Ireland. Today, ruby is still the highest valued colored gemstone and coveted as a romantic gift. Ruby is the birthstone for July and the gem for 15th and 40th anniversaries.

Color and Grading

The deep red of rubies is from the presence of chromium that replaces aluminum within the gem's chemical makeup. The more chromium there is, the deeper the red will be. Although there are pink and orange sapphires, only gems with pure red color are considered ruby. 

The Gemological Institute of America (GIA) does not assign grades to rubies, but they complete an identification report with the shape, cutting styles, transparency, color, species, variety, and geographic origin. This report also gives information on whether it has been treated, carat weight, measurements, and any other comments that the gemologist may make. View a sample report here

Value and Customization Options

Like other colored gemstones, color is usually a very significant factor when shopping for a ruby. Deeper, more vibrant color usually will mean a higher value for the ruby. However, if a ruby has significant inclusions, this will affect value as well. As carat size increases, the price will increase. Keep in mind, this is the most valuable colored gemstone in the world; when dealing in larger carat weights, some rubies may sell for more than a diamond of the same carat. 

Ruby is a very classic gem, and looks gorgeous when placed in a vintage piece. Diamonds are a perfect complement to ruby and all metal tones work well. Rubies can also be used as accent stones, like on the ring below.
