July Birthstone

Ruby, the king of precious gems, is the birthstone for fortunate folks born in July. Symbolic of the passion and energy associated with the color red, the vibrant ruby is said to bring love and success.

Ruby Overview

Ruby is the red variety of the mineral corundum, colored by the element chromium. All other colors of gem-quality corundum are called sapphire, which means color is key for this royal stone.

Accordingly, the name “ruby” comes from rubeus, the Latin word for red. In ancient Sanskrit, ruby translated to ratnaraj, which meant “king of precious stones.” These fiery gems have been treasured throughout history for their vitality.

The chromium that gives ruby its red color also causes fluorescence, which makes rubies glow like a fire from within. Paradoxically, chromium is also what makes this gem scarce because it can cause cracks and fissures. Few rubies actually grow large enough to crystallize into fine quality gems, and these can bring even higher prices than diamonds.

Burma’s Mogok Valley historically produced the finest ruby material, famous for its deep blood-red color with purplish hues. These Burmese Rubies, also called Pigeon’s Blood Rubies, command a premium over brownish or orange-tinged varieties from other regions.

The Mong Hsu region of Myanmar began producing rubies in the 90s after discovering that heat treatment improved the color saturation. Other ruby deposits exist in Vietnam, Thailand, India, parts of the Middle East, East Africa and even the United States.

Tough and durable, ruby measures 9 on the Mohs scale. Diamond is the only natural gemstone harder than ruby.

Ruby’s strength and red fluorescence make it valuable for applications beyond jewelry. Both natural and synthetic rubies are used in watchmaking, medical instruments and lasers.

Due to its deep red color, ruby has long been associated with the life force and vitality of blood. It is believed to amplify energy, heighten awareness, promote courage and bring success in wealth, love and battle.

Ruby History

ymbolic of passion, protection and prosperity, the ruby has been revered since ancient times.

Rubies have been particularly prized in Asian countries. Records suggest that rubies were traded along China’s North Silk Road as early as 200 B.C. Chinese noblemen adorned their armor with rubies because they believed the gem would grant protection. They also buried rubies beneath building foundations to secure good fortune.

Ancient Hindus believed they’d be reborn as emperors if they offered rubies to the god Krishna. In Hindu folklore, the glowing fire within rubies burned so hot that they allegedly boiled water. Greek legends similarly claimed that ruby’s warmth could melt wax.

In Burma—a significant ruby source since at least 600 AD—warriors believed that rubies made them invincible. They even implanted rubies into their skin to grant protection in battle.

Many cultures also admired ruby as a symbol of love and passion. Rubies have long been considered the perfect wedding gem.

Though ruby has a long history, it wasn’t recognized as a variety of corundum until 1800. Prior to that, red spinel, tourmaline, and garnet were also believed to be ruby. Even the Black Ruby, one of the famed crown jewels of England, was considered one of the largest cut rubies until determined to be spinel.

Imitation ruby dates back as far as Roman times, though it wasn’t synthesized until the early 1900s.

The red fluorescence power of ruby helped build the first working laser in 1960. Rubies—both natural and synthetic—are still used to make lasers, as well as watches and medical instruments.

After classical Burmese mines depleted, the Mong Hsu region of Myanmar started producing rubies in the 1990s. Though these lacked the rich red hue of traditional Burmese Rubies, they were treated with heat to improve saturation and transparency. Heat treated rubies is a common practice nowadays.

 Emerald Overview

As the birthstone for May, the emerald, a symbol of rebirth, is believed to grant the owner foresight, good fortune, and youth. Emerald, derived from the word “smaragdus,” means, quite literally, “green” in Greek.

Like aquamarine, emerald is a variety of beryl, a mineral that grows with six sides and up to a foot in length. Emerald color can range from light green (though there is some argument whether these very light beryls are truly emeralds) to a deep, rich green. Emeralds are also like aquamarine in that the way the color is presents itself in jewelry depends on a good cut by a skilled gemologist.

The deeper or more green an emerald, the more valuable it is. The rarest emeralds will appear to be an intense green-blue.

Emeralds are found all over the world, including Colombia, Brazil, Afghanistan and Zambia. The availability of high-quality emerald is limited; consequently, treatments to improve clarity are performed regularly.

 Emerald History

The emerald was mined in Egypt as early as 330 BC, but some estimate that the oldest emeralds are 2.97 billion years old.

Cleopatra is perhaps the most famous historical figure to cherish emeralds. She even claimed ownership of all emerald mines in Egypt during her reign.

The Egyptians used emeralds both in jewelry, and in their elaborate burials, often burying emeralds with monarchs as symbols of protection.

On the other side of the world, the Muzo Indians of Colombia had well-hidden and prized emerald mines. These mines were so hidden, it took the Spanish conquistadors nearly twenty years to find them.

Like other gemstones, the emerald was believed to have many mystical powers that accompanied its beauty. There were those who thought the emerald could cure stomach problems, control epilepsy and stop bleeding. Maybe due to its soothing green color, it was also thought to be able to ward off panic and keep the wearer relaxed and serene.

Today, emerald is a symbol of loyalty, new beginnings, peace and security, making it not only a beautiful gem to wear, but also a meaningful gift to be treasured by the receiver. It is still widely prized by the rich and famous, with Elizabeth Taylor’s famous emerald pendant selling for $6.5 million in 2011.
