Understanding Ruby Pricing
Calculating the price of a ruby is significantly more complex than diamonds because color is the most critical factor. Unlike diamonds, there is no single "Rapaport" list for rubies; value is determined by the rarity of the specimen's characteristics.
The "Pigeon Blood" Premium
The term Pigeon Blood refers to a specific, highly saturated red with a soft blue fluorescence. These rubies, especially those from the Mogok region of Burma, command the highest prices in the gemstone world, often exceeding $10,000 to $50,000 per carat for high-quality stones.
Heat Treatment Impact
Approximately 95% of rubies on the market are heat-treated to improve color and clarity. An unheated ruby of the same visual quality can be worth 3 to 10 times more than a heated counterpart because of its natural rarity.
