Alexandrite. A variety of chrysoberyl found in the mica slate of the Ural mountains. It is of a rich garnet color by transmitted light; by daylight of a dark moss green. It is the only stone that so changes. The finest specimens or alexandrite are nearly as valuable as diamonds.
“Christ's ... yoke is an easy yoke; his burden like the burden of wings to a bird, that makes her fly the higher.”
