In the pearl quality grading, glossiness is an important indicator to measure the value of pearls. To accurately quantify the glossiness of pearls, it is necessary to use an instrument to measure the glossiness of pearls. Since pearls are small in size and have curved surfaces, a microporous high-precision gloss meter can be used. This article introduces the method of measuring the glossiness of pearls with a microporous gloss meter.

Pearls are the same as any other gemstones in that their prices vary with their quality. Consumers focus on pearl quality in terms of location, color, shape, and smoothness. Simply put, high-priced pearls have large locations, strong light, popular colors, perfect roundness or special shapes, and flawlessness. A relatively small improvement in a certain quality point of a pearl will lead to a significant increase in its value. Its special natural luster makes it unique among many jewelry, which also determines that luster is an indicator for evaluating the upper limit of pearl value.
Pearl gloss is both a biological property of shellfish and the ability of the pearl's own surface to reflect mirrors. The greater the gloss, the closer the pearl surface is to complete mirror reflection. Physically, polishing is only a measure to improve the gloss of pearls, and it cannot make a qualitative breakthrough in the gloss of pearls. Therefore, it is very important to improve the gloss of cultured pearls, and artificially cultivated high-gloss pearls have important economic value. Since pearl gloss has become an indicator of high-value pearls, scholars have been continuously studying pearl gloss. Therefore, in order to accurately measure the gloss of pearls and provide data support for the research on pearl gloss, a gloss meter can be used.

The naked eye evaluation of pearl gloss is easily affected by personal subjective factors. A large amount of evaluation and grading work can easily cause eye fatigue of the evaluator, resulting in large errors. With the upgrade of gloss measurement technology and measuring instruments, the qualitative description analysis has shifted to quantitative measurement analysis, and the gloss meter is an important tool for quantitative evaluation of pearl gloss. Since pearls are round and have curved surfaces, they can be measured using a microporous gloss meter for curved surface measurement. The application of this measurement method makes the entire measurement process more standardized, and directly uses the international gloss unit GU to express the pearl gloss value, which reduces errors. The measured gloss value can more accurately reflect the strength of the pearl gloss.
There are many brands of micropore gloss meters on the market. Here we recommend the 3nh YG60M micropore high-precision gloss meter. The YG60M gloss meter is a high-precision small-aperture handheld gloss meter, which is professionally used for gloss measurement of curved surfaces or ultra-small objects. The instrument adopts a 60° universal angle design, with a measuring range of up to 1000GU, simple operation and strong portability. It is widely used in gloss measurement and quality inspection in paints, inks, coatings, paper printing, plastic electronics, furniture, ceramics, electroplating, hardware, marble and other industries. The instrument has the following advantages:
1. Micropore design: It adopts a very small measuring aperture of 2x4mm, which is suitable for gloss detection of samples such as curved surfaces, irregular objects, and small objects, and has a wider range of applications.
2. High measurement accuracy: The carefully adjusted measurement system and optical path layout ensure stable and accurate gloss measurement, meeting the requirements of JJG 696 working gloss meter, with superior performance, which can completely match the test data of imported gloss meters.
3. Multi-mode measurement: supports basic mode, statistical mode, continuous mode, and quality control mode switching to adapt to different application scenarios. The normal mode is for immediate measurement and fast reading; the quality control mode can customize the upper and lower limits to achieve rapid inspection of incoming materials.
4. Calibration function: supports calibration, with the function of automatically checking the calibration standard plate to ensure the accuracy and reliability of long-term measurement.
5. Low power consumption: One fully charged No. 5 battery (AA alkaline battery or NiMH rechargeable battery) can measure more than 10,000 times.
6. Simple operation and easy to use: The instrument is easy to operate and can be used immediately after it is turned on. Data can be locked with one key. No complicated settings are required and the measurement can be completed in 0.5 seconds.
7. Lightweight and portable: The instrument is based on ergonomic design, with a compact and beautiful appearance and a comfortable grip. It is not only suitable for precise measurement in the laboratory, but also convenient for flexible application in the production site.
8. PC-side quality management software: The instrument is equipped with powerful PC-side data management software, which supports online measurement, prints test reports, transfers data, and realizes more functional expansion.
