The Unique Color-Shift Properties of Alexandrite and Why They Stand Out

Article: The Allure of Alexandrite - Rare Gemstones with Stunning Color Change

Alexandrite, a gemstone that captivates with its unique color-changing properties, has been a source of fascination since its discovery in 1834 in the Russian Ural Mountains. Named to honor the Russian Tsar Alexander II, this vibrant gemstone exhibits a remarkable transformation from green in daylight to red under incandescent light, a phenomenon that contributes significantly to its high value.

The color change effect in alexandrite is due to its equal transmission of green and red light. For a stone to be considered valuable, the color shift must be nearly complete and vivid, with distinct hues of raspberry red under incandescent light and bright green in daylight. Weaker color shifts or those involving less distinct hues like blue-green or brownish-red decrease the price significantly.

Size matters greatly in the world of alexandrite. Stones over 3 carats are extremely rare and command exponentially higher prices than smaller ones. Large, fine-quality alexandrites can sell for tens of thousands or even millions of dollars, reflecting both rarity and collector demand.

The stone’s origin also impacts value. Historic Russian alexandrites are especially sought after for their intense color change and rarity. Other origins such as Sri Lanka, Brazil, and Madagascar produce valuable stones but typically not at the same premium as Russian ones.

Other contributing factors include clarity and cut, certification, antique provenance, and the presence of rare chatoyant or 'cat's-eye' alexandrites. Well-cut stones that enhance the color change and have minimal inclusions fetch higher prices, while independent verification from reputable gemological labs adds to credibility and collector confidence. Alexandrite in historic jewelry, particularly from Russian mines, can be more valuable due to rarity and provenance.

Synthetic alexandrite has been produced since the 1960s, with synthetics having the same chemical, physical, and optical properties as natural alexandrite. However, synthetic alexandrite can be found in antique jewelry, as it has been produced since 1909.

The largest faceted alexandrite is from Sri Lanka, weighing 65.7 carats. Today, alexandrite is mined in Brazil, Myanmar, Tanzania, India, Madagascar, and Sri Lanka. Despite the increased production, large alexandrite specimens and those over five carats in weight are scarce.

Alexandrite belongs to the chrysoberyl family, which is separate from beryls. Chrysoberyls have a hardness of 8.5 on the Mohs scale, making them suitable for jewelry. Russian legend associates alexandrite with good luck, good fortune, and love.

In summary, the interplay of its uncommon double color change effect, limited supply of large quality stones, and desirable origins account for alexandrite’s notable rarity and high market value. Exceptional pieces are among the rarest and most expensive colored gemstones globally.
