Jadeite, known as the "king of oriental gemstones", is valued in large part by its density. Density is an important indicator to identify the authenticity of jadeite and evaluate its quality. So, how do you accurately measure the density of jadeite?This article will give you a detailed answer.
The basic method of measuring the density of jadeite is indirect measurement. First, you need to prepare a precision electronic balance, a container with distilled water, and a thin wire. Tie the jadeite with a thin thread and then hang it at one end of the balance to record the weight of the jadeite in the air. Next, the jadeite is completely immersed in distilled water and its weight in the water is recorded again after making sure it does not touch the walls of the container. From the difference between these two weights, the volume of the jadeite can be calculated. Finally, divide the weight of the jadeite in the air by its volume to get the density of the jadeite.
It should be noted that during the measurement process, it is necessary to ensure that the surface of the jadeite is clean and free of impurities and oil stains, so as not to affect the accuracy of the measurement results. At the same time, in order to ensure the accuracy of the measurement, it is recommended to use an electronic balance with high accuracy and take the average value of multiple measurements.
In addition to measuring density, observing the appearance characteristics of jadeite is also an important way to identify its authenticity. Natural jadeite typically has a delicate texture, a warm luster, and a distinctive emerald green color. Synthetic jadeite or treated defective products tend to have a rough texture, dull luster, and overly bright or dull colors.
In short, measuring the density of jadeite is one of the important means to identify its authenticity and evaluate its quality. Mastering the correct measurement methods and techniques, combined with the observation of the appearance characteristics, can help us more accurately identify the authenticity and value of jadeite.
