Because chromium creates narrow absorption bands in the yellow spectrum, the gem appears green when illuminated by balanced, blue-rich daylight and transforms to red-purple when exposed to incandescent or candlelight rich in red wavelengths. Untreated stones with clear, distinct shifts and sharp crystal clarity represent one of the rarest finds in fine gemology.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eBespoke Custom Jewelry Commission\u003c\/h3\u003e\n  \u003cp\u003e\n    This certified natural alexandrite is available as a loose investment gemstone or ready for custom mounting.
