The ancient Egyptians mined emeralds nearly 4,000 years ago, and Cleopatra was an avid collector. South America's rich bounty of emeralds was discovered by 16th Century Spanish explorers who found large emeralds in the possession of the Aztecs and Incas. Believed by the ancients to empower the owner with foresight into the future, emerald is regarded as an amulet for good fortune Emerald, to many, symbolizes rebirth and the abundance of the life force. The rich green hue brings to mind the regeneration of life in spring and hope of new possibilities. Emerald is the birthstone for May and a talisman for Gemini. Spring can also be seen in the network of inclusions in the depth of the emerald that the French call the jardin, or garden, because it resembles foliage. The inclusions are like a fingerprint, giving each emerald a distinct personality and distinguishing them as truly natural gemstones. Today, most of the world's emeralds are mined in Colombia, Brazil and Zambia. Emeralds can be cut in a variety of different shapes, ranging from the traditional rectangular step-cut, known as the "emerald cut," to rounds, ovals, squares and cabochons. Early gemstone merchants sought to purify the transparency of their emeralds by immersing them in clear oils or paraffin. They found that clear oils and waxes rendered surface fissures less visible to the eye. Today, we have many sophisticated technologies with which to clarity-enhance emeralds. In addition to the oils and waxes of ancient methods, we now use clear resins to penetrate the open fissures surfacing in the stones. Hardeners are often added to solidify these liquids. This step prevents the resin from evaporating, thus making the clarity enhancement more permanent than oiling or waxing the gem. Although emerald itself is quite durable, the garden of inclusions may make individual gems vulnerable to damage if handled roughly. |

Topaz sometimes has the amber gold of fine cognac or the blush of a peach, and all the beautiful warm browns and oranges in between. Some rare and exceptional examples are pale pink to a sherry red. Topaz is found in Brazil, Mexico, Sri Lanka, Africa and China. The birthstone for November, topaz is a talisman for the sign of Sagittarius and is the suggested gift for the 23rd anniversary. Blue, once the most rare color of topaz, is today the most common, thanks to a stable enhancement process that turns colorless topaz blue. After the raw topaz is extracted from the earth and cut, it is irradiated to brown and then heated to sky blue. This enhancement process is permanent. Due to the popularity of blue topaz, a new treatment process called vapor deposition has been developed to create additional colors of topaz. In this treatment process, similar to those used by opticians and camera makers to make lens coatings, a thin colored film is bonded on the surface of topaz to create dark blue, red, pink, and green colors or rainbow iridescence. These vapor deposition-enhanced topaz colors must be handled with special care, as the coating can be scratched or abraded. Topaz is a very hard gemstone, with a Mohs hardness of 8, but it can be split with a single sharp blow, a trait it shares with diamond. As a result it should be protected from hard knocks. Clean with mild dish soap; use a toothbrush to scrub behind the stone where dust can collect. Contact us and we can tell you how to best care for your topaz.
