Ruby Overview
Name: Ruby
Family: Corundum
Chemical Formula: Al2O3 (aluminum oxide)
Color: Red (due to chromium)
Hardness (Mohs): 9 (second only to diamond)
Crystal System: Trigonal
Luster: Vitreous (glass-like)
Transparency: Transparent to translucent
Color – The Most Important Factor
Ruby’s value is defined by its color, which must be red — no other color qualifies it as a ruby, even if chemically identical.
Best color: “Pigeon’s blood” red – a vivid, pure red with a slight bluish tone
Other tones: pinkish-red, purplish-red, orangey-red, brownish-red
The red comes from chromium; more chromium = deeper red
If a corundum is any color other than red, it is classified as a sapphire, not a ruby.
Origins and Sources
Top-quality rubies are found in:
Myanmar (Burma): Home of the finest rubies, especially from Mogok
Thailand: Darker rubies, often with brown or garnet-like tones
Sri Lanka (Ceylon): Lighter “pink sapphires” and ruby varieties
Madagascar: Newer source of bright, clear stones
Mozambique: Major modern source with high-quality stones
Clarity & Cut
Clarity: Most rubies have inclusions. Eye-clean stones are rare and valuable.
Common inclusions: rutile “silk,” fingerprints, needles, or crystals
Cut: Often cushion, oval, or mixed cuts to maximize color and brilliance
Carat: Large rubies (over 1 carat) are exponentially more valuable due to rarity
Treatments
Most rubies undergo treatments to improve appearance:
Heat treatment: Common and accepted; enhances color/clarity
Fracture-filling with lead glass: Makes heavily included stones look better but lowers value
Untreated rubies: Very rare and command premium prices
