Colored gemstones have been a rising trend among stars and fashion influencers. We love the new fashions incorporating luxurious gems into high fashion and even bridal looks. If you note our previous post we touched on many stars getting gemstone engagement rings instead of conventional diamond rings. Not all gemstones are created equal, the quality of a colored gem is a delicate combination of many factors. This post is to help ensure shoppers will get the best quality gem for what they are paying. Enjoy.
The factors that directly affect the appearance of a gemstone is a very detailed grading process. There are four C’s when it comes to grading a gem. Color, Clarity, Cut, and Carat Weight are all equally importance.
Color: For any colored gemstone, color is key. You must look at hue, saturation, and tone. The color of a gem must correspond to a color on the color wheel. Quality gems typically only closely resemble the primary colors red, green, and blue (RGB). Of course some color is purely personal preference but generally speaking the variation considered the best is always closer to it’s direct primary color. Saturation explains the richness of a colored gem. Typically fine jewelry gems have a higher saturation of color. Tone is referring to the lightness or darkness of a color. Look for stones with an even look under various lighting.
Clarity: Gemstone jewelry is another critically important aspect that affects durability and final grading. The smaller the number of inclusions the better. You do not want to see any unhealed cracks; the smoother the appearance the better the durability.
Cut: Shape is everything for many gemstone enthusiasts since it’s revered shape is the outline of the gem. Typically speaking, rounds and emerald shapes are rarer than oval styles. Symmetry, length to width ration, and depth percentage are also critical grading factors that influence a well cut gemstone.
Carat Weight: For a gemstone, weight is calculated using carats which 5 carats equals one gram. In the market for gemstones, weight can in fact have the biggest influence on price. For example, a 0.99ct stone might be worth much less than a 1.05ct stone due to repolishing and the type of scale
