Description
This spectacular 4.25-carat unheated Brazilian alexandrite is an extraordinary natural wonder—a perfect example of the coveted color-change phenomenon. Unlike their Russian counterparts, which change from green to red, alexandrites that hail from the mines of Brazil display a stunning bluish-green hue under white light and change to a rich, deep purple when viewed under incandescent light.

This spectacular 4.25-carat unheated Brazilian alexandrite is an extraordinary natural wonder—a perfect example of the coveted color-change phenomenon. Unlike their Russian counterparts, which change from green to red, alexandrites that hail from the mines of Brazil display a stunning bluish-green hue under white light and change to a rich, deep purple when viewed under incandescent light. This stunning marquise example is graded by both the GIA and Gübelin as free from heat treatments, meaning its rare color-changing effect is completely nature-made. In its report, Gübelin also rates this magnificent stone as "superior," underscoring its exceptional quality. Set in platinum with two diamond accents totaling 1.06 carats, this ring is an exquisite rarity.

While the alexandrite was first discovered in the Ural Mountains of Russia in the 1800s, many of the finest examples of these stones have been found in Brazil. For example, the 17.08-carat stone known as the Whitney alexandrite can be found in the Smithsonian Museum of Natural History, having been gifted to the National Gem Collection by Carolyn Wright Whitney. Like this gemstone, the Whitney alexandrite changes from bluish-green in daylight and fluorescent light to an intense purple in incandescent light. In terms of both rarity and originality, Brazilian alexandrites are in a class all their own.
