Dahl Jewelers, Woodbridge, VA
Alexandrite, Alexandrites

Perhaps no other gemstone in the world has acquired its mystique as rapidly as alexandrite.

In 1830, workmen at a mine in Russia's Ural Mountains discovered a wondrous new gem. When viewed in sunlight, it was green; however, when inspected under artificial light, it turned red.

Since this new gem was found on the birthday of Czar Alexander II and since the national colors of Russia were red and green, the new gem was named alexandrite.

The demand for alexandrite quickly spread around the world and desire for alexandrite quickly outstripped the mine's production of the stone. The search began for new sources of alexandrite and it was also discovered in places such as Sri Lanka, Zimbabwe and Brazil.

Its scarcity, beauty and color-changing ability make alexandrite a very desirable and valuable gem. Today, the demand for good quality alexandrite insures that it will remain one of the most preferred gems in the world.
