When it comes to determining the quality of a diamond, most people start by looking at the 4Cs — carat, color, clarity, and cut. These are the fundamental factors that influence a diamond’s value and appearance. However, while the 4Cs are essential, they aren’t the only things you should consider when evaluating a diamond. There are several other details that can significantly impact its overall quality and beauty.
First, always make sure the diamond is not set in a piece of jewelry. Once it's mounted, it becomes much harder to accurately assess its true quality. The setting can obscure certain characteristics, making it difficult to judge the diamond’s actual clarity or color. If you're buying a diamond, it's best to have it removed from the setting for a more accurate evaluation.
Second, different settings can affect how a diamond looks. Some metal settings might make the diamond appear whiter or yellower than it actually is. Additionally, the prongs used in the setting can hide small imperfections on the diamond. Diamonds are the hardest natural material on Earth, but improper handling during setting or removal can cause damage, especially to the edges. This can lower the diamond’s value. Always ensure the diamond is clean and properly examined before purchasing.
Third, lighting plays a crucial role in how a diamond appears. Under sunlight or yellow light, a diamond may look brighter, but this isn't an accurate way to evaluate it. Instead, use a pure white light source without ultraviolet rays and examine the diamond with a 10x magnifying glass. This allows you to see internal flaws and inclusions that might not be visible to the naked eye. A well-cut diamond reflects light beautifully, but you need proper tools to fully appreciate its brilliance.
Fourth, dirt and grime can dull a diamond’s sparkle and make it look yellow. To maintain its shine, diamond jewelry should be cleaned regularly using a soft brush and a cleaning solution, or by using an ultrasonic cleaner. Before assessing a diamond, it must be thoroughly cleaned to ensure an accurate evaluation of its color and clarity.
Fifth, the American Gem Society (AGS) and other institutions classify diamonds based on color and clarity. Color grades range from D (colorless) to Z (yellowish), with D-F being considered colorless, G-I as nearly colorless, and beyond I being slightly yellow. For clarity, FL (Flawless) and VVS1 (Very Very Small Inclusions) are top-tier, while VS (Very Slight) and SI (Slight) are also acceptable for most buyers. At OL Jewelry Network, we offer diamonds with color I or better and clarity VS or higher, ensuring you get a high-quality piece that’s worth investing in.
