Size has a major impact on the value of every beautiful gemstone. Since each gem is unique, there is considerable variation in size. Some gems, like quartz, can be quite large, while others, like blue spinel, tend to be smaller. Understanding how to determine size will help you in selecting gemstone jewelry.
What is the Best Gemstone Size?
The preferred size of a gemstone depends on personal taste. Larger gems make a statement, smaller gems offer a more subtle allure, and sizes in between provide excellent versatility in style. The significance of the gemstone can also play a role in choosing the one that's best for you.
How to Measure Gemstone Size
Gemstone size is measured in terms of carat weight and surface dimensions. Carat weight indicates the weight of the gem, but it's not the best measure of a gem's visual size. This is because different gems have different densities, meaning two gems with the same carat weight won't necessarily have the same proportions. For example, a 2-carat ruby is smaller but denser than a 2-carat diamond, thus weighing the same as a less dense diamond.
Generally, larger gemstones are more valuable than smaller ones. Buying more smaller gems to reach a certain total carat weight often saves money compared to purchasing a single gem of the same weight. For instance, four ½-carat emeralds or rubies cost less than one 2-carat emerald or ruby.
Viewed from above, the dimensions of a gemstone can more accurately depict its size. By observing the diameter, length, or width of the gem, you get a visual sense of how much area the gem will show when set.
