1.00 ct Green Alexandrite - Pear

At 1 carats, this alexandrite from Brazil carries its green color through a pear cut, measuring 6.8 x 5 x 3.9 mm.

Alexandrite is the color-change chrysoberyl, green in daylight and red under lamplight; few gemstones genuinely change hue, and this is the one that defined the effect. Brazil has been one of the most prolific colored-gemstone sources in the world for a century, and still turns up new material on a regular basis. It carries no treatment of any kind, so the color you see is the color that came out of the ground. It is GIA-certified, and the report is available to view.

Few stones reach this combination of size and quality, and fewer still come to market. We will tell you everything we know about it before you decide.
