Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a pearl size measuring device. Background Art

[0002] Pearls, also known as mussel pearls and lian pearls, are an ancient organic gemstone, mainly produced in pearl shellfish and mother-of-pearl shellfish mollusks. Pearls are mineral beads containing calcium carbonate produced by the endocrine function of shellfish, and are composed of a large number of tiny aragonite crystals. There are rich varieties, different shapes, and colorful colors.

[0003] Among them, among pearls of the same variety, the larger the size, the scarcer the number and the higher the price. There are also large differences in the size range of pearls between different varieties. For example, the common size of freshwater nucleus-free pearls is 5-8mm, the common size of freshwater nucleus pearls is 11mm-16mm, and the South Sea golden pearls produced by golden lip oysters are very large, so the cultivated South Sea golden pearls are also very large. The common size is generally 9-15mm, and the largest can reach 18mm.

[0004] Generally, when workers classify the sizes of pearls, they often use calipers to measure the pearls of the size to be measured. They pinch the pearls between two fingers, and the caliper clamps the pearls through two thin clamping arms. Especially for small pearls, the pearls are not stable during clamping measurement, which affects the data of pearl size measurement. Therefore, we propose a pearl size measuring device.
