Ruby: A Red Symbol For Fiery Passion

Rubies have a rich history and stunning appearance, often representing fiery passion for wearers. Whether you are looking for a gift, an investment, or a personal treat, rubies are a great choice for your jewelry. 

What is Ruby?

A ruby is a red type of corundum, a mineral composed of aluminum and oxygen. When a corundum is blue, it is known as a sapphire (other colors are called "fancy" sapphires). The red color of a ruby is determined by the amount of chromium in the crystal structure. The more chromium the stone has, the more intense and vivid the red color. 


Rubies are the second hardest gemstone after diamonds, with a rating of 9 on the Mohs scale of hardness. 


The image showcases a striking array of red gemstones with varying shapes and sizes, from sharp, faceted gems to larger, textured raw stones. They are spread out on a reflective surface, which, along with the soft gradient background, beautifully highlights their sparkling facets and rich, translucent red color.

Why Choose It for Your Custom Design?

  • Rubies are rare and durable. They come in stunning shades of red, from pink to purple to orange, and are the second hardest gemstone after diamonds (with a rating of 9 on the Mohs scale of hardness). They can withstand scratches, heat, and chemicals. And rubies are scarce in nature, especially in larger sizes and finer qualities, making them more valuable and collectible than other gemstones.
  • Rubies are often considered the stone of love, passion, courage, and power. They can express a range of sentiments, from romance to loyalty to confidence. Rubies are the birthstone for July and the traditional gift for the 15th and 40th wedding anniversaries. Ruby is also associated with the zodiac signs of Aries, Leo, and Sagittarius. It resonates with these fire signs,  bringing passion, vitality, and courage.

What to Consider When Purchasing

  • Color is the most important factor for rubies. The most valuable rubies have a pure red color with a slight blue or purple undertone. Rubies with too much orange or brown are considered less desirable and are often less expensive. The color should be even and consistent throughout the stone, without any noticeable zoning or patches.
  • Rubies are usually expected to have some inclusions, or internal flaws, that affect their transparency. These inclusions can enhance the beauty and value of the ruby (like the inclusions that create the effect in star rubies). However, the inclusions should not be too visible or too numerous, as they can reduce the brilliance and durability of the stone.
  • The cut can affect the color, clarity, and sparkle of the ruby. Cut refers to the shape, proportions, and polish of the ruby. The proportions and symmetry of the ruby should be balanced and well-proportioned, to maximize the light return and minimize weight loss (the most common shapes are oval, round, cushion, and emerald). The polish should be smooth and even.
  • Larger rubies with a higher carat size are often (but not always) more rare and expensive than smaller rubies. The carat of a ruby should not be the only criterion for buying a ruby, as a smaller ruby with a better quality can be more valuable than a larger ruby with a lower quality.
  • The origin of a ruby can affect its color, clarity, and rarity. Some of the most famous and prestigious origins are Myanmar (Burma), Thailand, Sri Lanka, Madagascar, and Mozambique. However, a ruby from any origin can have a high quality and a high value, depending on the individual characteristics of the stone.

Interesting Facts

  • Rubies were revered by many ancient civilizations, including the Egyptians, Greeks, Romans, Indians, and Chinese. They were believed to have various powers for protection, wisdom, health, and fortune. They were also used as offerings to gods and kings, as symbols of royalty and authority, and as talismans and amulets.
  • Rubies were the first gemstones to be artificially synthesized in a laboratory in the late 19th century. Synthetic rubies have the same chemical composition and physical properties as natural rubies and are used for various purposes, such as lasers, watches, and jewelry. They are not as valuable or rare as natural rubies, and they can be distinguished by various tests and methods.
  • Some of the most famous and valuable rubies in the world are the Sunrise Ruby, the Graff Ruby, the Hope Ruby, the Carmen Lucia Ruby, and the Liberty Bell Ruby. Some of these rubies have been sold for millions of dollars, stolen by thieves, or donated to museums and institutions.
The image features a symmetrical design with a large, red, faceted gemstone at the center, flanked by classical figures in mirrored stances. On the left, a figure holds a balance scale and stands beside a lion, symbolizing balance and strength. On the right, a figure holds a torch next to an ox, representing enlightenment and sacrifice. Intricate patterns and smaller red gemstones within circular motifs surround these elements, all set against a dark background that emphasizes the vivid colors.

Our Recommendation for Ruby in Custom Jewelry Designs


A Bold and Fiery Statement

  • Rubies captivate with their intense, fiery red hue. Throughout history, this vibrant color has symbolized love, passion, and desire. When you wear a ruby, you exude confidence, strength, and individuality.
  • Because rubies rank 9 on the Mohs hardness scale, they withstand daily wear, resist scratches, and don't break.

Could Be Out of Budget

  • If you’re seeking a fiery red gemstone but working within a tight budget, high-quality rubies might feel expensive and out-of-range.

We adore the vivid, fiery red of rubies—no other gemstone can quite match their color. Equally captivating is their enduring strength, durability, and symbolism. They make a powerful statement as everyday jewelry while gracefully withstanding the test of time.


If love the color but are looking for a different price point, a couple other gemstones come to mind:

  • Garnet is another durable gemstone that comes in an array of colors (including red).
  • Spinel can be a great alternative (although a high-quality red spinel can still be a little expensive).
