Everything You Need to Know About This Brilliant Red Gemstone
Ruby corundum is one of the most admired gemstones in the world, prized for its vivid red color, remarkable durability, and timeless appeal. Whether featured in fine jewelry, statement rings, or elegant pendants, ruby corundum has captivated gemstone lovers for centuries.
But what exactly is ruby corundum, and how does it differ from other gemstones? Let's explore its origins, characteristics, and why it remains a popular choice in modern jewelry.
Ruby and Corundum: What's the Connection?
Many people are surprised to learn that ruby is actually a variety of corundum.
Corundum is a naturally occurring mineral composed primarily of aluminum oxide (Al₂O₃). When trace amounts of chromium are present during its formation, the crystal develops its signature red color and is classified as a ruby.
In simple terms:
-
All rubies are corundum.
-
Not all corundum is ruby.
Corundum found in colors other than red is generally referred to as sapphire.
What Gives Ruby Its Red Color?
The stunning red hue of ruby comes from chromium.
The amount of chromium present influences the intensity of the color, ranging from pinkish-red to deep crimson.
The most valuable rubies display a rich, vibrant red often described as "pigeon blood red," a color highly sought after by collectors and jewelry enthusiasts.
How Durable Is Ruby Corundum?
Ruby corundum ranks 9 on the Mohs hardness scale, making it one of the hardest gemstones used in jewelry.
Only diamond ranks higher.
This exceptional hardness makes ruby an excellent choice for:
-
Everyday rings
-
Earrings
-
Pendants
-
Bracelets
-
Heirloom jewelry
With proper care, ruby jewelry can maintain its beauty for generations.
Natural vs Lab-Grown Ruby Corundum
Today, ruby corundum is available in both natural and laboratory-grown forms.
Natural Ruby
Natural rubies are formed deep within the Earth over millions of years.
They are highly valued due to their rarity and unique inclusions.

Lab-grown rubies have the same chemical composition, hardness, and optical properties as natural rubies.
They offer several advantages:
-
Excellent clarity

More affordable pricing

Consistent color

For many jewelry lovers, lab-created ruby corundum provides an accessible way to enjoy the beauty of ruby without the premium price associated with fine natural stones.
