About Pearls

Pearls are an ancient organic gemstone. They are primarily produced in the bodies of pearl and mother-of-pearl bivalve mollusks; the pearl grains containing calcium carbonate minerals (aragonite) are formed by endocrine action and are composed of large aggregations of tiny aragonite crystals. According to the research of geology and archaeology, pearls have existed on Earth for over two hundred million years. China is truly a country with a long history of pearls, with records dating back to 2200 BC. The international gem industry also lists pearls as the birthstone for June, the anniversary gem for the 13th and 30th wedding anniversaries.

 

 

About Flaws

 

As natural treasures that are generated without processing and are endowed with magical vitality, 100% flawless pearls are theoretically non-existent. This is because even when viewed with the naked eye, it is difficult to see, but with a magnifying glass of 10 times or even higher, one can still observe the natural growth patterns and uneven surfaces on the pearl's surface. In practical terms, there are indeed some pearls that are almost invisible to the naked eye or are extremely difficult to see any imperfections. In the commercial application field, industry experts refer to these as flawless. In the national standard for "Pearl Grading Standards," the definition of "flawless" is "observed with the naked eye, the surface is smooth and delicate, and it is extremely difficult to see any imperfections." Most pearls farmed have some degree of threads, depressions, and other imperfections on their surface. This is also the theoretical basis for the old saying, "No flaw, no pearl."
