Let’s dive in.
Part 1: The Origins: Where Do Garnet and Ruby Come From?
Garnet
Garnet is not a single mineral but a group of related silicate minerals. The most commonly used garnet in jewelry is pyrope garnet, famous for its deep, wine-red hue. Other varieties like almandine and spessartine can range from orange-red to purplish-red.
Historically, garnet has adorned jewelry dating back to the Bronze Age. Ancient Egyptians prized garnet amulets, and Roman signet rings often featured engraved garnet cabochons. Today, garnet is mined in countries like India, Madagascar, Sri Lanka, Mozambique, and the United States.
Ruby
Ruby, by contrast, is a variety of corundum, the same mineral family as sapphire. What sets ruby apart is the presence of chromium, which gives it its vivid red color. The most prized rubies exhibit a pure, rich red with a slight blue undertone—often referred to as “pigeon blood red.”
Rubies have been cherished for over 2,000 years. Ancient Burmese warriors believed rubies made them invincible. In Sanskrit, ruby was called “ratnaraj”—the king of precious stones. Today, the finest rubies come from Myanmar (Burma), Mozambique, Sri Lanka, and Thailand.
Color and Appearance
Though both stones are red, their hues are distinctly different upon closer inspection.
-
Garnet typically shows a deeper, more wine-like red, often with brownish undertones.
-
Ruby displays a bright, intense red with hints of pink or blue, depending on the origin.
Transparency and brilliance also differ:
-
Garnet has a softer, velvety luster.
-
Ruby, being corundum, is more transparent and often exhibits higher brilliance and fire.
Tip: Under natural daylight, rubies usually appear more vivid, while garnets can look darker.
Symbolism and Meaning
Garnet:
-
Traditionally associated with protection and strength.
-
Believed to inspire love, devotion, and loyalty.
-
The birthstone for January.
-
Often gifted as a 2nd wedding anniversary stone.
Ruby:
-
Symbolizes passion, vitality, and power.
-
Historically linked to nobility and royalty.
-
The birthstone for July.
-
A popular choice for 40th wedding anniversaries (ruby anniversary).
When choosing between the two, consider the symbolism that resonates with you or your recipient.
Durability: Which Is Better for Everyday Wear?
When investing in a gemstone ring—especially one you plan to wear often—durability is a major factor.
-
Garnet measures 6.5–7.5 on the Mohs scale, making it moderately hard but susceptible to scratching with rough wear.
-
Ruby ranks 9 on the Mohs scale, second only to diamond. This makes ruby extremely durable and well-suited for engagement rings and daily-wear pieces.
Verdict: If you want a ring you’ll wear daily, ruby is the safer choice for long-lasting beauty.
Value and Price Considerations
One of the biggest differences between garnet and ruby is their price point.
-
Garnet is affordable, making it an excellent choice if you’re on a budget. Even large garnets rarely exceed a few hundred dollars per carat.
-
Ruby is one of the most expensive colored gemstones in the world. High-quality rubies over 1 carat can cost several thousand dollars per carat, and the rarest examples can exceed $100,000 per carat.
Why the dramatic price difference?
-
Rubies are rarer in fine, clean, vivid red qualities.
-
Rubies often come with prestigious origins (Burmese rubies).
-
Rubies retain value and are considered an investment-grade gemstone.
How to Tell Garnet from Ruby
While some red garnets can look surprisingly similar to rubies, gemologists use several tests to distinguish them:
-
Refractive Index:
-
Garnet: 1.73–1.89
-
Ruby: 1.76–1.77
-
-
Double Refraction:
-
Garnet: Single refractive
-
Ruby: Doubly refractive (birefringent)
-
-
Inclusions:
-
Garnet often has “horsetail” or granular inclusions.
-
Ruby can show rutile silk or fingerprint inclusions.
-
-
UV Fluorescence:
-
Ruby glows red under UV light.
-
Garnet usually does not fluoresce.
-
-
Spectroscope:
-
Garnet shows broad absorption bands.
-
Ruby displays chromium absorption lines.
-
If in doubt, a certified gemologist or a reliable grading lab can provide identification.

Garnet vs. Ruby for Engagement Rings
If you’re considering a red gemstone engagement ring, here’s a quick comparison:
