Weight: Guide weighing gems

In gemology, the precise weighing of gems is essential for determining their value. This article provides a comprehensive guide on how to correctly consider the gem, what information we can obtain with the help of its weight, and how the gemological laboratory is rounding the weight.

Caurat Weight: History and Specific Unit

First, it is necessary to understand what exactly carat weight means. Karat (CT), as a unit of weight, is used to express the weight of gems. Do not confuse with carat purity (KT), for example, expressing the purity of gold. The history of carat weight goes back to ancient times, when one carat (CT) was the equivalent weight of the plant of the plant called the corner or carob. Currently, one carat is defined as 0.20 grams. This standardization is crucial for universal understanding and comparing the weight of gems around the world.

Dear Precision:

When weighing the gems, the essential high rate of accuracy is essential. Karat weights, like those from Sartorius, which we offer in our assortment, have the accuracy of weighing up to tens of thousands of carats. This accuracy is essential, especially in rare and high -value stones, where even a small difference in weight can significantly affect the value.

Weight rounding in gemological laboratories

In the practice of gemological laboratories, the weight of the gems is rounded to two decimal places. This process, however, is not only mathematical rounding. It is based on specific rules and standard procedures that may vary depending on the laboratory. This rounding takes into account various factors, including business habits and historically established standards. Most of the gemological laboratories round up from nine and all that rounds down the number 9. This means that a 0.999 CT diamond would be rounded to 1.00 CT while a diamond weighing 0.998 will be rounded to 0.99 CT.

Determination

The weight and proportions of the gem, in combination with the specific weight of the material, can be key to identifying the type of gem. For example, a diamond has a specific weight different from other stones, which can help distinguish a diamond from other minerals.

Dear gems is a sophisticated process that requires not only precise technical equipment, but also basic knowledge of gemological principles. Proper weighing and interpretation of the weight of the gem is key to determining its value, type and authenticity. In our Arete Tools e-shop we provide high-precision carat weights and other equipment that helps gemologists in this essential part of their work. Our products and services are designed to meet the highest standards in the field and help professionals in the field of gemology to achieve the best results in their evaluation and analysis of gems.
