Sometimes you’ll see two gems that seem the same size, and even the same color, but the value could be vastly different. That difference can result from many different factors. The value of a gemstone, determined through gemology studies, can be attributed to some physical features and how well-known, crafted, and rare the stone is. Understanding how to identify gemstones and value them correctly is an ability that is developed through gem studies.
Gemstone value starts with color; it is what first attracts the eye and it can make the most difference in the value of the gem. Different colors, different levels of saturation, and how that saturation is distributed throughout the gem can all determine value.
Gemstone clarity, or internal features, is another important value consideration. Internal gem features, or inclusions, can be as small as to be virtually invisible, or as large as to detract from clarity and brilliance, or they could just make the gem look natural. The quantity of inclusions, their size, and location will all help determine value.
The cut of the gemstone plays a great role in the quality and value of the stone, as this determines how well the stone reflects or refracts light, or simply how well it shines and appears to the naked eye. Even the most precious and rare gemstone can be ruined by a bad cut. A well-cut gem will be brilliant and have good proportions for the light to hit it right.
Another key element that can affect the value of a gemstone is the stone’s rarity. Some gems are only found in a few locations worldwide or there may only be a few pieces of it available each year. Geological conditions that affect mining, or the availability, can contribute to gemstone rarity, and rarity can contribute to high value.
How the gemstone is treated can also affect the value of the gem. Gemstones can be treated by heating or other clarity enhancing methods. Treatments of any kind are quite common, and not necessarily frowned upon, however transparency regarding such procedures is essential for accurate valuation and consumer confidence.
The market for different gems fluctuates with market forces. Fashion, celebrity trends, and other market demands can drive the value of certain gemstones. The value of a gemstone must be constantly reviewed and re-evaluated by gemologists to account for these market trends.
Evaluating a gemstone’s value is a complex process that uses many different skills to ensure accurate appraisal. By combining gemological sciences with market knowledge, gemologists are able to accurately value the unique gem and understand its place in the gemstone market. The study of gems opens up a whole new world of knowledge and ability and understanding the gemstones of the past, present, and future can be quite the challenge.
