Understanding Alexandrite Values
Alexandrite is often called the most remarkable gemstone in the world, prized for its extraordinary color-change phenomenon. In daylight, fine alexandrite appears vivid green; under incandescent light, it transforms to vivid red or purplish-red. This dramatic shift, caused by the way chromium atoms absorb light, makes alexandrite one of the rarest and most valuable colored gemstones on Earth.
Origin and Its Impact on Value
Russian alexandrite from the Ural Mountains, where the stone was first discovered in 1830, commands the highest prices. These stones display the classic green-to-red change considered the benchmark for the species. Brazilian alexandrite, discovered in the 1980s, offers strong color change at somewhat lower prices. Sri Lankan stones tend toward olive green and brownish-red, while African sources provide more affordable options.
The color-change phenomenon is the single most important value factor. Stones showing a complete shift from pure green to pure red command exponential premiums over those with partial or muddy color change. A 1-carat alexandrite with strong color change can be worth 5-10 times more than a similar-sized stone with weak color change, making this characteristic far more significant than clarity or cut in determining value.
