DETAIL: A remarkably gorgeous, sparkling, oval cut vivid, intensely blue colored faceted zircon with all the flash and brilliance of a diamond. Renown for the production of the fabled gemstones and jewelry of Russian Czars from the Medieval through Renaissance and Victorian Eras, this gemstone was hand cut and hand polished by a 19th century Russian artisan for use in indigenous jewelry. It looks ever so much like a rich, intense, blue colored diamond - the vivid blue bringing to mind the clear, vibrant blue color of a alpine lake on a bright summer day. Zircon was used for centuries as a diamond substitute, and in general can easily fool most anyone, even many jewelers, into believing that they are diamonds. They are exceeding difficult to distinguish from the highest quality diamonds due to their high refractive index.

Under magnification the gemstone shows the unmistakable characteristics of having been hand crafted. The coarseness of the 19th century finish is considered appealing to most gemstone collectors, and is not considered a detriment, or detract from the value of a gemstone. These characteristics are not only expected of hand-finished gemstones, most serious collectors consider such gemstones more desirable, possessed of greater character and uniqueness when compared to today's cookie-cutter mass-produced machine-faceted gemstones. Unlike today's computer controlled machine produced gemstones, the cut and finish of a gemstone such as this is the legacy of an artisan who lived two centuries ago. For most, the unique nature and character of antique gemstones such as this more than makes up for included imperfections which by and large, are only visible under magnification.

This gemstone possesses superb luster and sparkle, and to the eye is completely transparent, but one cannot say with absolute certainty that it is absolutely flawless. True, the blemishes it possesses are not visible to the naked eye, and the gemstone can be characterized at a minimum, to use trade jargon, as "loupe clean". To the eye it is indeed flawless; however magnified 600%, as it is here, you might be able to just barely pick out one or two slight imperfections within the gemstone, barely perceptible even at such high magnification. Of course the same may said about almost any natural gemstone. An absolutely flawless gemstone simply is not the rule in nature. Most absolutely flawless gemstones will upon close examination be revealed to be synthetic. You might also notice under magnification occasional irregularities in the cut and finish.

Naturally these characteristics are not only expected of hand-finished gemstones, you must also consider that two centuries ago the mining techniques prevalent did not allow the ultra deep mining operations which are so common today. Keep in mind that two centuries ago mankind was more or less limited to surface deposits or near surface deposits of gemstones. Higher quality gemstones which today are routinely mined from beneath hundreds of meters, even kilometers beneath the earth's surface, were simply inaccessible then. For these reasons antique gemstones must be appreciated as antiques first, gemstones second. The relatively superlative quality of contemporary gemstones routinely mined from deep beneath the earth's surface today were simply not accessible two centuries ago, or at least, only rarely so. However for most, the unique nature and character of antique gemstones such as this more than makes up for included imperfections which by and large, are (if at all) only visible under high magnification.

HISTORY: The word zircon originated in the 18th century from the Persian word "Zargon", which means "gold colored", due to the yellow color of the zircon gemstones found there. In history the first references are in Hindu mythology, many thousands of years old. In Europe in the Middle Ages zircon was also worn by travelers as a protective amulet, and was believed to ward off lightning strokes. It was believed to drive away plagues, evil spirits, and nightmares. Zircon occurs in a rainbow of colors including blue, yellow, green, brown, orange and colorless. Over the years, zircon has been called by many names. The name "hyacinth" or "jacinth" was used for reddish brown zircon. "Jargon", or "jargoon", described lighter yellow to nearly colorless zircons.

Historically the colorless form of Zircon, known as "Matara diamond", has been the most popular and the most costly. White zircon as it is called today looks more like diamond than any other natural stone due the high refractive index of zircon. These physical properties cause zircon to come very close to diamonds in fire and brilliancy. Blue zircon was immensely popular in the 1880's and was used extensively in Victorian jewelry. In fact, jewelry from this period is a principal source today of blue zircons over five carats. Blue zircon and colorless zircon remain the most sought after and costly forms of zircon. Colorless zircon is occasionally confused with "cubic zirconia" due to the fact that both have been used a substitutes for diamonds. Cubic zirconia is a man-made synthetic gemstones. Zircon is a natural gemstone.

Most of these antique gemstones were originally part of two collections, one originating in India principally composed of gemstones originally mined in India, Burma, Ceylon, and Siam, and then hand faceted in India. The addition of a second accumulation of antique gemstones originally mined in the Urals in the mid to late 19th century (including alexandrite) completed the collection. These gemstones as well were hand finished. The Urals have been one of the world's major sources of precious and semi-precious gemstones for many centuries. As well, additional specimens are occasionally acquired from other institutions and dealers in Eastern Europe and Asia. These antique gemstones are now in the United States and are available for immediate delivery.
