When you buy pearls, you must often see the name "Akoya", but please don't misunderstand that it is a brand or the name of the place of origin, "Akoya " is actually the name of a marine shellfish, Mallet's clam, which originated in the South China Sea. Its Chinese name is Akoya. Akoya is the transliteration of Japanese. In ancient times, Akoya pearls were called "Southern Pearls", and in Japan they were "Japanese Pearls".
AkoyaPearls can be said to be synonymous with high-quality pearls. The surface of the pearl is covered with a layer of high-quality calcium crystals, giving it the strongest luster and halo, and the pearlescent light can even be clear. Reflecting the reflection of a person, its body colors include white, silver-blue, and yellow, as well as accompanying colors and iridescence colors, and silver-blue and golden yellowAkoya pearl production Less, more expensive than white pearls of the same grade.
Natural Akoya pearls have become rare due to overfishing and ocean pollution, and in 1893, MikimotoMikimoto's founder, Mr. Kokichi Mikimoto, successfully cultured pearls for the first time and applied for a technology patent for this. Japan's Akoya pearls are mainly produced in the Seto Inland Sea in Mie, Kumamoto and Ehime Prefectures. The maximum diameter can be produced 10mm of pearls; while Chinese Akoya pearls are mainly produced in Guangxi and Guangdong. The pearls produced are generally between 5~7mm. Due to the Akoya's 7~8mm Pearls are relatively rare, so Japanese Akoya pearls larger than 8mm are more popular in the market.
In terms of breeding quality, artificial breeding conditions for seawater pearls are relatively complex, and attention must be paid to changes in pollution, temperature, and ocean currents in the breeding sea area. Therefore, their general value is higher than that of freshwater pearls. In addition, Akoya pearls are cultivated using core insertion culture technology, aAkoya Generally only one pearl is harvested, compared to seedless culture and one pearl oyster can produce more than 20-30 pearls at a time Pearls, Akoya pearls will not be deformed due to multiple pearls squeezing each other. The shape is more regular, closer to a perfect circle, AkoyaPearls are of high quality but have low output. Japan has strict control over the quality and output of Akoya pearls, and has maintained a steady upward price trend in the market.
