And the coincidence was too good to leave alone: green and red were the colours of the Imperial Russian military. A stone found on Russian soil that wore the empire's colours and changed between them depending on the light.\u003c\/p\u003e\u003cp\u003eIt became, briefly, the most fashionable gem in Russia. \u003cstrong\u003eA stone that was loyal in two lights.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe physics is chromium in chrysoberyl, sitting in a narrow window where the crystal transmits both green and red almost equally and lets the light source decide.
