Gemstone Inclusions: What Are They? Inclusions within a gemstone are generally known as imperfections such as shards, or slithers, or pieces, of another mineral that is trapped inside the main stone as it is being formed – perhaps being left behind during the process. They can also manifest themselves as bubbles, small crystals and other small fractures caused in the formation of the host material. Many different gemstones are affected by inclusions. In fact, most diamonds do have inclusions of some sort. It is very rare to find an inclusion-free diamond gemstone. Diamonds will lose value if they have inclusions of any sort, however, as mentioned, diamonds without inclusions are very rare. Some inclusions are seen by the naked eye, but most imperfections can only be seen via magnification. Sometimes jewelry buyers can use this to their advantage by buying a diamond with inclusions far more cheaply than buying a diamond that is perfect. As most consumers will not be able to identify inclusions if they looked hard enough, the magnification process can often be exploited. To the right is a simple example of inclusions like shards and needles during the main gemstone formation.
Most gemstones will lose a little value if they have inclusions. But we have to consider the effect the inclusion will have on the “vision value” of the inclusions in the gemstone. For instance, sapphire and rubies often have inclusions termed as “silk.” These silk inclusions form as needle-thin structures that have their own reflection properties within the main stone. These varying reflections can often be very interesting to see, based on ambient and artificial light source. Sometimes these needle-thin inclusions produce what is known as a “star effect” and the viewer can see a six-point pattern in a sapphire or ruby.
It is worth remembering that there are very few gemstones in today’s marketplace that do not contain some form or other of inclusions. Having said that, a gemstone like a sapphire or ruby doesn’t necessarily lose value because of inclusions. It is probably certain that an inclusion will not have its value enhanced by the presence of inclusion, however, it may not necessarily lose value either. As they say, beauty is in the eye of the beholder, and very often one or two inclusions can enhance the stone value in the mind of the beholder.
