Gem Grade

  • Gems are graded by four qualities, known as the “four C’s.” These stand for Color, Clarity, Cut, and Carat, (meaning size.)
    The first thing a consumer needs to understand is that gemstones are graded by the rarity of their features. Even though we use the term “quality” that does not necessarily mean that one gem is better than another. On the contrary, what is best for you personally may not be the top, or rarest grade of a gem.
  • When a mineral deposit is found there will be a wide variety of qualities. For example, let’s say someone just mined 100 pounds of amethyst. One of the first things the grader will notice is the size variation. The smaller stones will settle to the bottom of the pile and the larger ones will demand the most attention. There are fewer large stones, so they will receive a higher grade in the size category than the smaller ones. 
  • 100-carat stone is much less common than a one-carat stone and that feature will add to its value. However, simply being larger does not mean that it is better. A small woman could not wear a huge stone gracefully. This would not be the best gem for a small person.
  • The same principle applies to the other grading factors as well. As the grader goes through his gems, only a few of the amethyst will have the absolute deepest and richest coloring. These will demand special attention and special pricing. However, the boldest colored stones are not the best match for every complexion, or every personality. Pastels are more feminine than bold colors and will suit some people much better.
  • So, as you read the following descriptions understand that the grades have to do with the rarity of the feature. They do not mean more durable, (with a single exception,) more beautiful, or better suited to your needs. When choosing a gem, look for the one that will give you the most enjoyment.
