Diamond Grading and Stone Identification

Precision Gem Lab offers a comprehensive diamond grading and stone identification service that can help customers determine the quality and value of their precious stones. Whether you have a loose diamond or a piece of jewelry that needs to be appraised, our expert gemologists can provide you with an accurate and detailed analysis of your stone.

Our diamond grading process involves a thorough examination of the stone’s 4Cs: carat weight, cut, color, and clarity. We use advanced equipment and techniques to measure the carat weight of the diamond and assess its cut quality, which determines how well the stone reflects light and sparkles.

We also evaluate the diamond’s color and clarity, which are both important factors that can affect its value. Our gemologists use a grading scale that ranges from D (colorless) to Z (light yellow or brown) to determine the diamond’s color grade. For clarity, we examine the stone under magnification to assess the number, size, and location of any inclusions (internal flaws) or blemishes (surface irregularities).

In addition to diamond grading, we also offer stone identification services to help you determine the type of gemstone you have. Our gemologists use a variety of methods, including visual inspection and testing with specialized equipment, to identify gemstones such as sapphires, rubies, emeralds, and more.

At Precision Gem Lab, we pride ourselves on providing accurate and reliable diamond grading and stone identification services. Our expert gemologists have years of experience in the field and are committed to providing our customers with the information they need to make informed decisions about their precious stones.
