Why is ruby considered a precious gemstone?
Ruby belongs to the corundum family, just like sapphire. What makes it an exceptional precious stone is the unique intensity of its red hue, its remarkable rarity, and its high hardness (rated 9 out of 10 on the Mohs scale), just below diamond.
Particularities of ruby
Mined rubies often feature inclusions that are not seen as flaws but as marks of authenticity. These inclusions help distinguish natural rubies from imitations and synthetic versions. Their frequent fluorescence intensifies their red glow under certain lighting conditions.
Most sought-after colors and qualities
The most valuable rubies display a deep, vibrant red known as pigeon blood. Prized for its beauty, saturation, and rarity.
Historical and current countries of origin
Historically, the most famous rubies come from Burma (Myanmar), especially from the Mogok Valley. Today, ruby deposits are also actively mined in Mozambique, Thailand, Vietnam, Sri Lanka, and Madagascar.
