Natural Brazilian Alexandrite Cushion Cut with Color Change Effect
This exceptional natural alexandrite is among the rarest and most valuable gemstones worldwide, renowned for its unique and striking color change phenomenon, which makes it highly sought after by collectors and high jewelry houses alike.
The gemstone originates from Brazil, one of the very few regions globally known for producing alexandrites with strong and well-defined dichroism. It exhibits a bi-color / multicolor appearance, with hues shifting depending on the light source—typically from green or bluish-green tones in natural daylight to red, purple, or burgundy tones under artificial lighting.
The alexandrite is 100% natural and completely untreated (Not Enhanced), with no thermal or chemical intervention. The absence of any treatment significantly elevates its rarity, collectible importance, and long-term investment potential.
The excellent quality cushion cut (Excellent Cut Grade) has been carefully selected to maximize the color change effect while offering elegance, balance, and color intensity. Cushion cuts are considered ideal for alexandrite, as they allow light to interact with the gemstone in a way that enhances its dramatic chromatic transition.
Eye Clean clarity ensures that the stone appears clean to the naked eye, with no visible inclusions an exceptionally rare characteristic for high-quality natural alexandrites.
The gemstone is accompanied by certification confirming its natural origin, color change phenomenon, lack of treatment, and full technical specifications. The cutting was performed in India, a country with a long-standing tradition and expertise in the precision cutting of rare gemstones.
