History: Alexandrite was discovered in 1830 in the Ural Mountains of Russia and named after Csar Alexander II. The original locality for alexandrite is Russia, however, fine gems have also been found in Brazil, Sri Lanka, Tanzania, Madagascar, Zimbabwe, India, and Burma.

Since the 1960s, labs have grown synthetic alexandrite—not to be confused with simulated alexandrite, which is actually corundum or colored crystals infused with chromium or vanadium for color. Creating synthetic alexandrite is an expensive process, so even lab-grown gemstones can be expensive.

Silver's history is long. The first evidence of silver mining dates back to 3000 B.C., in Turkey and Greece, according to the RSC. Ancient people even figured out how to refine silver. They heated the silver ore and blew air over it, a process called cupellation.

The term "sterling silver" probably originated in eastern Germany when five towns formed the Hanseatic League in the 1100s. These town minted their own coins of 92.5 percent silver. When Britain sold cattle and grain to the League, they were paid in "Easterling coins".
