Revered as the king of gemstones across countless ancient cultures, Ruby remains one of the most coveted precious stones in history. Here's what makes it so extraordinary.
What Is Ruby?
Ruby is the red variety of corundum (aluminum oxide, Al₂O₃), colored by trace chromium. Chemically, it's the very same mineral as sapphire — the only difference lies in the trace element responsible for its color (chromium for ruby's red, iron and titanium for sapphire's blue).
A fact that surprises most people: ruby is the second-hardest mineral found in nature, trailing only diamond.

What Does "Pigeon Blood" Mean?
Burmese rubies from Myanmar, with their intense, slightly purplish red reminiscent of a pigeon's blood, are considered the most coveted and valuable in the world. A sizable "Pigeon Blood" ruby can command prices that exceed those of an equivalent diamond.
The Meaning and Energy of Ruby
It activates the root and heart chakras, awakening inner strength, courage, determination, and creative passion. It is considered one of the most protective and energizing stones in the mineral kingdom.
Caring for Your Ruby
- ✅ Thanks to its exceptional hardness (9), it's among the most resilient stones for daily wear.
- ✅ Clean with lukewarm water and mild soap.
- ❌ Avoid ultrasonic cleaning if the stone shows visible inclusions.
- ❌ Avoid direct impact on the edge of the cut.
Frequently Asked Questions About Ruby
What's the difference between ruby and sapphire?
They're the same mineral (corundum). Ruby is the red variety (colored by chromium); every other corundum color, including blue, is called sapphire.
Can ruby be worn every day?
Yes, without hesitation. At hardness 9, it's among the most scratch-resistant gems in existence.
Why are some rubies so expensive?
Price depends on color ("Pigeon Blood" is the most prized), clarity, size, and origin. Large Burmese rubies are extraordinarily scarce.
What gemstones pair beautifully with ruby?
It pairs spectacularly with emerald and sapphire (the classic combination of the "big three" colored gems), as well as with amethyst and rhodolite.
