| Emeralds By Fred Ward |

EMERALDS
Fabulous emerald crystals came from what is now Colombia. It took Spain five decades to overpower the Muzo Indians who occupied the mining area. Monarchs and the gem-loving royalty in India, Turkey, and Persia sought the New World treasures once the gems arrived in Europe. The new emerald owners produced spectacular artifacts between 1600 and 1900, such as the "Atocha Cross" (right). Fabricated in Colombia and lost underwater in the Florida Keys for more than two centuries, the Spanish Colonial specimen recently sold for $750,000. Today Colombia, Brazil, and Zambia mine most commercial emeralds. Several other countries, such as Pakistan and Zimbabwe, produce smaller amounts. Although Brazil mines more emeralds annually than any other country, Colombia dominates the trade by setting the standards for size and color. It is Colombian emeralds against which all others are judged. Rarer and sometimes more expensive than a similar-sized diamond, Colombian emeralds have a unique look, a green lightly touched with blue. Muzo, the original mine, remains the most important emerald mine in the world. This contemporary ring is an example of the quality Colombian emeralds Mr. Ward obtains for clients. Notice the bezel-set emerald. Emeralds are often accused of being "soft," which is not true. Because of the molecular makeup and the typical presence of multiple inclusions, some emeralds can be brittle. For rings meant to be worn daily, we usually recommend bezel setting (surrounding the gem with metal instead of setting it up on prongs). This precaution protects the stone from anything except a direct top blow |

Description : |
DIAMONDSDiamonds, best known of the world's gemstones, have fascinated potentates and collectors since their discovery near Golconda, India around 800 B.C. Austria's Archduke Maximilian began a tradition in 1477 now considered integral to diamonds' financial success. To symbolize his love for Mary of Burgundy, the duke was first to incorporate a diamond into a wedding ring. That use makes diamonds the most expected and purchased of all major gemstones. Seldom do accolades meet reality, but diamonds deserve all the superlatives showered on them. These gorgeous jewels, the crystal form of carbon, rate a 10 on the Mohs hardness scale of 1 to 10 as the hardest material in nature. Diamonds will scratch anything else, including other diamonds. And with an outstandingly high refractive index of 2.41, diamonds dazzle with rainbow hues. To a gemologist, a material has to have three qualities to be classified as a gem: beauty, durability, and rarity. Clearly diamonds qualify.

| Rubies & Sapphires By Fred Ward |

RUBIES AND SAPPHIRES
Rubies & Sapphires are paired in Fred Ward's new book because they belong together. Even though they appear to be vastly different, they are actually color variations of the same thing, the mineral species corundum, which is aluminum oxide. Rubies and sapphires are fraternal twins, chemically the same except for minute amounts of trace elements that produce different colors. Sapphires occur in every color of the rainbow but one, because if corundum crystals are red, they are known as rubies. Rubies are always red, but sapphires can be blue as well as pink, yellow, green, black, colorless, orange, teal, and lavender. Much of the allure of sapphires is the number of available colors. One of the unfortunate legacies of a huge marketing effort in the 1960s, when Australia's almost-black sapphires became available, is the mistaken notion that sapphires should be dark. That advertising gimmick caused buyers to seek dreary, opaque inexpensive dull stones. In his book Fred Ward recommends buying only bright and beautiful sapphires, such as the ones in the array at right from Sri Lanka. Shop for blue sapphires that appear blue in room light at night. If they die under artificial light avoid them. All the stones here except the red rubies are sapphires. Notice the different shades of blue as well as the brilliant yellow sapphires. Because they are rarer, rubies cost more than sapphires, which remain the bargains of the four major gemstones. The highest sapphire prices begin with the finer blues and for a very special peachy-pink gem from Sri Lanka, known as "Padparadscha." Prices then decrease as you move from pink to orange, violet, yellow, and green sapphires. Rubies & sapphires occur in a number of countries. Burma (Myanmar) is most famous as a source for both. Burmese rubies and sapphires fetch a premium in the market because of their perceived superior colors. Burma ruby prices soared during the 1980s and only recently abated because of a new discovery at Mong Hsu. Rubies are also found in Thailand, Cambodia, Kenya, Tanzania, Afghanistan, India, and in a small non-commercial deposit in North Carolina. Sapphires are mined commercially in Thailand, Australia, China, Tanzania, Kenya, Nigeria, and, surprisingly, in Montana. In fact, as pointed out in our new book, Montana is one of the gem trade's best-kept secrets. Large quantities of very colorful sapphires are quietly produced in the U.S. Most are sold and cut overseas, only to reenter the market as Thai or Australian sapphires. Because sapphires are relatively plentiful, they are somewhat easier to match than other colored gemstones. Only Montana and the mining area around Umba in Tanzania produce enough richly varicolored sapphires to produce a rainbow tennis bracelet set entirely with sapphires. This example was made with a brilliant array of Montana sapphires. Similar bracelets are available from Fred Ward.
Rubies & Sapphires are ideal gems, harder than all others except diamonds.
They possess a high refractive index, making them both durable and
brilliant, sure to give a lifetime of satisfaction. |
