To assess the clarity of a tsavorite gemstone, you can follow these steps:
-
Visual Inspection: Start by visually examining the tsavorite under good lighting conditions. Look for any visible inclusions, such as cracks, fractures, or other internal flaws. Hold the stone up to a light source and observe if there are any obvious blemishes or cloudiness within the gem.
-
Loupe Examination: Using a jeweler's loupe, which is a small magnifying device, inspect the tsavorite more closely. A loupe with 10x magnification is commonly used for gemstone examination. Hold the loupe close to your eye and bring the tsavorite up to the loupe, allowing you to see the stone's details more clearly.
-
Inclusion Evaluation: Look for any internal inclusions, such as tiny crystals, fractures, or other imperfections. Note the type, size, and location of the inclusions within the stone. It's important to remember that almost all natural gemstones have some degree of inclusions, but the significance and impact on the stone's appearance and value may vary.
-
Clarity Grading: Based on the observed inclusions, you can assign a clarity grade to the tsavorite. The Gemological Institute of America (GIA) has a widely used clarity grading scale, which includes the following categories: Flawless (FL), Internally Flawless (IF), Very Very Slightly Included (VVS1, VVS2), Very Slightly Included (VS1, VS2), Slightly Included (SI1, SI2), and Included (I1, I2, I3). Assigning a clarity grade helps determine the value and overall quality of the tsavorite.
It's important to note that assessing clarity requires experience and expertise. If you are unsure about evaluating the clarity of a tsavorite or any gemstone, it is recommended to consult with a professional gemologist or a reputable jeweler who can provide a comprehensive and accurate evaluation. They have the necessary tools and knowledge to thoroughly examine gemstones and provide you with detailed information about their clarity characteristics.
