Crystal Red Cognac Amber

A specimen of deep crystal colors found only in Mexican amber. This large piece of amber is a deep crystal red; when tilted, the color transforms to a cognac green. These specimens are called “stop lights” by the locals, because of their stop light-like ability to change from red to green.
