Details

Alexandrite is a faceted phenomenal gemstone known for its distinct color change, shifting from a cool bluish-green in daylight to a reddish-purple under incandescent light—often referred to as “emerald by day, ruby by night.” A stone over 5 carats with a pronounced color change and notable clarity is exceptionally rare, placing it among the most highly sought-after examples of this remarkable gem variety.

Care

Design

Oscar Heyman is defined by an uncompromising pursuit of rare and exceptional gemstones. Thousands of gems are evaluated using exacting standards for color, luster, and cut, yet only a select few are chosen. Among them are remarkable “phenomenal gems,” whose unique inclusions and crystal structures transform as light moves across their surface. Alexandrite is prized for its rare color-change phenomenon, shifting from bluish green in daylight to rich purplish red under incandescent light.
