4.561 carat laboratory-grown alexandrite, oval cut, accompanied by its original AGL Laboratory Grown Gemstone Report. This is a substantial loose stone at approximately 9.0 × 11.0 × 5.9 mm. It shows the characteristic color-change behavior of alexandrite, appearing in shades of pink, raspberry, purple, red, and cooler blue/violet tones depending on the lighting. The photos show the actual stone being sold in several different lighting conditions, including natural sunlight. Because alexandrite is highly lighting-dependent, its exact color and strength of color change will vary depending on the light source and viewing environment.
