The Ultimate Guide to Rubies

Rubies, the gemstone of love, are renowned for their striking hardness and vibrant hues, ranging from pink to deep red. Across various cultures, rubies symbolize luck, possess healing properties, and boost self-confidence. Delving deeper into symbolism, medical astrology suggests that wearing a ruby can restore vitality, improve eyesight, and enhance blood circulation.

At My Jewelry Repair, our passion for rubies inspired us to create this Ultimate Ruby Guide. We hope you find this guide to be an informative and comprehensive reference, whether you’re shopping for rubies or caring for the ones you already own.

What Features Should We Look for in a Ruby?

Rubies are among the most expensive gemstones, with record prices exceeding $1,000,000 per carat. They are often subjected to more treatments than almost any other gemstone.

When discussing the anatomy of a ruby, we turn to the 4 C’s:


  • The cut of a ruby is critical to its overall appearance and value.
  • Rubies are typically cut with great precision to minimize natural fractures and maximize brilliance. Unlike diamonds, rubies are often found in flat, hexagonal shapes.
  • A quality cut can enhance the ruby’s natural beauty and protect it from damage and wear, making it a striking piece in any jewelry collection.


  • Inclusion-free rubies are extremely rare, and experts generally expect to find some inclusions in natural rubies.
  • The value of a ruby is significantly influenced by the visibility of these inclusions.
  • Inclusions that reduce transparency or brightness can lower the value of a ruby, whereas less noticeable inclusions may not have as significant an impact.
  • The clarity of a ruby is a testament to its natural formation and can add to its unique character.


  • Ruby size can vary significantly in terms of weight and density.
  • While rubies come in a range of sizes, fine rubies over 1 carat are exceptionally rare and highly prized.
  • The larger the ruby, the rarer it becomes, and therefore, more valuable. However, it’s not just the size that matters; the quality and color of the ruby also play crucial roles in determining its overall worth.


  • Color is the most crucial factor among the 4 C’s when it comes to rubies.
  • Fine rubies exhibit a vibrant red or slightly purplish hue, known as “pigeon blood red,” which is considered the most desirable.
  • Rubies that are more orange or have a pronounced purple hue are generally lower in value.
  • The color of a ruby is a major determinant of its appeal and price, with the most intense and pure red hues being the most sought after.

In summary, when choosing a ruby, consider the cut, carat, clarity, and color to find a gemstone that is not only beautiful but also a true reflection of its remarkable qualities.

Natural vs. Lab-Created Rubies

Let’s discuss an important trend in the jewelry industry: lab-created gemstones.

What is Considered “Real” and What is Considered “Fake” When it Comes to Rubies? Lab-created gemstones are common today, and rubies are no exception. Lab-created rubies are made by combining specific minerals, resulting in their signature fiery red color.

Flame fusion rubies are among the most inexpensive synthetic options and are produced quickly. The differences between lab-created and natural rubies can generally only be identified by an expert.

Features of Rubies

Rubies are composed of corundum, a crystalline form of aluminum oxide. Formed under extreme heat and pressure beneath the Earth’s surface, these gems emerge with their stunning beauty.

Corundum initially appears colorless, created by densely packed oxygen and aluminum atoms. When these aluminum atoms are replaced by other elements, the gemstone transforms and gains its color.

Rubies are one of the four precious gemstones, alongside diamonds, sapphires, and emeralds. Rubies also share the corundum gem family with sapphires.

Rubies exist only in shades of red and pink. Their vibrant red hue is due to the presence of chromium. The more chromium in the stone, the redder it appears. In some cases, high chromium levels can give the ruby a deep red color with hints of purple or blue under certain lighting conditions. Ironically, chromium also contributes to the rarity of rubies, as it causes fissures and cracks within the gemstone. This chemical paradox makes high-quality rubies in large sizes extremely rare, driving their value even higher than that of diamonds.

A Brief History and Symbolism of Rubies

The first rubies were reportedly discovered in Burma (Myanmar) around 600 A.D. This region remains a significant source of rubies, although it has been marred by the world’s longest civil war. Consequently, rubies from this area are sometimes referred to as “Blood Rubies,” akin to the term “Blood Diamonds” from West Africa.

Today, rubies are also mined in Vietnam, Tanzania, Mozambique, India, East Africa, the Middle East, Thailand, and the United States. Each region produces unique varieties of rubies, with five major types being the Burmese ruby, Thai ruby, Mozambique ruby, Madagascar ruby, and Tanzanian ruby, all highly prized in jewelry.

While the first recorded discovery of rubies was in 600 A.D., these gems hold special significance in texts predating that time, spanning various cultures and religions.

  • Judaism: In the wisdom tradition, rubies have long been associated with wisdom, as mentioned in the Book of Proverbs.
  • Judeo-Christian Tradition: Rubies are referenced throughout sacred texts. For instance, in the Book of Revelation, it describes: “The one who sat there had the appearance of jasper and ruby” (Revelation 4:3).
  • Hinduism: In Sanskrit, the ancient language of Hinduism, the ruby is called Ratnaraj, or “king of precious stones,” signifying its supreme status among gems.

Throughout history, radiant red rubies have been associated with good fortune, health, wisdom, and success in love, particularly in Medieval Europe. Some believe rubies possess healing powers, protecting their owners from harm and illness. These powers were thought to include regenerating the physical and spiritual heart, enhancing circulation, and strengthening immunity for both body and mind. While these beliefs are ancient, the ruby remains one of the strongest gemstones, second only to the diamond.

Rubies continue to captivate hearts and minds across cultures and ages, making them a timeless and cherished gemstone.

Picking the Perfect Ruby for Your Jewelry

Ruby characteristics and the jewelry that showcases them should reflect your unique personality.

  • Consider what type of jewelry you’re incorporating rubies into – a ring, a tennis bracelet, a necklace, or earrings?
  • Choose the precious metal you prefer and find the one that looks the most aesthetically pleasing.
  • Think about the cut you want and what looks best to you.
  • Decide if the ruby will be featured alone or if the piece will have side stones accompanying the ruby.

Each of these questions will help you select the perfect ruby for your setting and better visualize the look you’re trying to achieve.

Caring for Your Rubies

Rubies are durable gemstones, resistant to heat, light, and many chemicals. They can even endure ultrasonic and steam cleaning treatments. However, rubies with fractures and cavities should be polished with a damp cloth. Soak them in warm, soapy water and use a soft cloth for the final polish.

  • Clean and polish your rubies once a week.
  • Soak your ruby jewelry in warm, soapy water. For finer gemstones, use a soft-bristled toothbrush to gently remove dirt and oil.
  • If using a sink, remember to block the drain to prevent any mishaps.
  • Avoid using toothpaste and other strong cleaning agents, as these are abrasive and can damage your rubies despite their durability.
