How can one purchase the fire and scintillation desired in a diamond at a reasonable price? This is the question diamond lovers everywhere who are deterred by high gemstone prices are asking. The once popular, inexpensive synthetic substitute, cubic zirconia (CZ), is heavier and far less fiery than real diamond, and larger CZs can't even pass for real to the naked eye. However, all is not lost. Lab- created diamonds are finally here, and they aren't pale imitations of the real thing any longer. These flawless gems ARE the real thing -- chemically and visually identical to natural stones.
Cultured, or man-made, stones are the same carbon crystals with the same chemical, optical and physical properties as those stones that nature created in the underground mines throughout the world. Cultured stones offer the same brilliance, sparkle, fire and scintillation. The Gemological Institute of America (GIA) grades the cultured gems by the same standards it uses for the mined ones, although its rating describes the stones as "laboratory grown." In fact, the GIA acknowledges that these ARE diamonds, just man-made.
In nature, colored diamonds rarely occur. These are the result of certain impurities - nitrogen will create yellow, boron will create blue, and so forth. Because there are so few colored natural stones of high quality, they are quite expensive. However, lab produced stones are readily available in several different colors. In addition to being flawless, the cost for cultured colored diamonds is similar to the cost for colorless stones.
Similar to their natural counterparts, cultured diamonds can be purchased either loose, or already in jewelry settings. Most jewelry and department stores don't carry them, however. These stones have only just been introduced to the market, and still comprise only a small portion of the total diamond inventory out there.
Some differences to be aware of with man-made diamonds include: 1. They are generally available in 1-2 carat weights. Larger stones are made, but are the exception, rather than the rule. 2. Most man-made stones are colored, rather than colorless - exactly the opposite of what occurs in nature. 3. Experts can detect that these gems are "synthetic" but special equipment is required to be sure and this equipment is expensive. 4. It is not difficult to find "matched pairs" of identical stones for use in jewelry. This of course has historically been very difficult and expensive in natural stones.
If you are concerned that someone may try to pass off a created diamond you are interested in purchasing as "the real thing," rest assured that this scenario is not all that likely. Firstly, lab-grown diamond producers are very proud of the gems they are able to create. Secondly, cultured diamonds are absolutely genuine, not "cheap" imitations. Thirdly, the difference between natural and cultured is detectable. Finally, jewelers have every incentive to preserve the integrity of the natural diamond market. Thus, a jeweler will readily help you identify the stone in question.
The bottom line is you will be able to purchase more for less, but you are unlikely to be able to get lab-grown diamonds on a beer budget. You can expect to pay approximately one third less for lab produced stones than for those found in nature. Lab-produced stones are readily available via the internet, and openly advertise that these are "synthetics." But, as with all internet purchases, be sure to check out the vendor as carefully as possible before you buy.
