May Birthstones
Emerald is the birthstone for May. Emerald is the most precious stone in the beryl group. The wonderful green color of emerald is unparalleled in the gem world. Emerald, by definition, is a medium or darker green to blue green beryl, in which the green color is derived from impurities of chromium, vanadium, or a combination of both. The most popular and valuable color is a slightly bluish green in a medium dark tone with strong to vivid saturation. Clarity is important, but inclusions are tolerated more in emerald than virtually any other gem. Unlike other beryl gems, emeralds often contain inclusions and other flaws. These flaws are not looked on as negative aspects for emerald like they would be for other gemstones. Indeed, these flaws are considered part of the character of the stone and are used to assure the purchaser of a natural stone. Emeralds are thought to ensure good health for the wearer.

The astrological stone for Gemini is agate. Agate is a form of chalcedony quartz that forms in concentric layers in a remarkable variety of colors and textures. Agate was highly valued as a talisman or amulet in ancient times. It was said to quench thirst and protect from fevers. Collecting agate bowls became common among European royalty during the Renaissance and many museums in Europe, including the Louvre, have spectacular examples.

Agate is found in many locations in the world, including Brazil, Uruguay, Australia, India, China, Madagascar, Mexico, Mongolia, Namibia and the USA.
