Whether you give them to yourself or buy them for someone else, colored gemstones are well loved stones. If you own a gemstone that does not feature visible imperfections (flaws or inclusions), the stone is deemed more valuable than a stone that displays imperfections.
Identifying Colored Gemstones
A colored gemstone identification considers the value of a gemstone, based on its special properties and individual characteristics. You may have admired some costume jewelry. Often, this kind of jewelry imitates colored gemstones in nature by using synthetic stones.
While gemstones do feature inclusions, it is not necessarily a bad thing. Those inclusions are just part of a stone’s formation. Yes, some stones are held more valuable without the marks. However, some inclusions are just part of the stone’s overall “personality.” For example, emeralds form in nature with easily identified inclusions. In this case, those inclusions are not considered negative. They merely set the emerald apart in the gemstone marketplace.
What Is the Carat Weight of the Stone?
When colored stones are evaluated, they are also appraised for the carat weight. This standard unit of weight is used by both gemologists and fine jewelers. One of the gemstones—the ruby—rarely is larger than a carat in size. Therefore, any ruby that is larger than a carat is considered valuable.
Another consideration in valuing gemstones is the color. Besides inclusions, the color is assessed. More valuable gemstones are clearer – or exhibit a high-definition appearance. A colored gemstone with a dark or medium tone will often command a higher price, depending on the type of stone.
Measuring the Hardness of the Stones
To measure the hardness of a stone, a Mohs hardness scale is used. Garnets, for example, feature a hardness of 7.0 on this scale. These stones can be found in both Europe and the United States. They were very popular in the early 20th century, and, therefore, frequently command high prices in the antique market.
While gemstone identification is primarily done to assess the value of a stone, it also pays homage to the mystical qualities of colored stones. For instance, in ancient Rome, the emperor Nero regularly used emeralds to protect his eyes when he watched gladiators fighting. The purple amethyst, which is closely related to quartz, was once closely associated with Dionysus – the Greek god of wine.
Caring for Your Colored Gemstones
Once you have a colored stone identified, it is also a good idea to learn something about its care. For example, if you have determined the value of an opal, you should make sure that the stone is not exposed to water or extended periods of extreme cold or hot temperatures.
An amethyst may fade if it is exposed to bright sunlight, over time, so keep that in mind after it has been examined. Garnets are one hardy stone, as they stand up to daily wear.
With that being said, establishing value is based on any defects, the color of the stone, and its size or carat weight. If you collect the stone, store them away to prevent damages. Preferably, store the colored gemstone jewelry in a padded box or soft cloth bag.
