0.47 ct Blue Alexandrite - Oval

This 0.47-carat alexandrite is cut as an oval measuring 4.3 x 3 mm, with a blue body color, sourced from Brazil.

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 is entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

One of a kind, it exists exactly once; there is no second example to size up or down. It is the rarer object, and the kind of gemstone that becomes an heirloom. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
