Will the color of the irradiated pearls fade?
Compared to the natural silver-gray, it will be more stable because the nucleus has turned black, so it will not fade significantly. Natural silver-gray Akoya pearls are caused by brown secretions mixed between the pearl nucleus and the pearl layer, and the color of the pearl will become lighter over time.
Since August 2017, the "Specially Selected Pearl" has been subdivided into two grades, "SUPEARL" and "GRANPEARL", with "SUPEARL" using a gold tag and "GRANPEARL" using a silver tag. In the new classification, the original "Specially Selected Pearl" are equivalent to the graded "GRANPEARL", while those of better quality and rarer than the "GRANPEARL" are called "SUPEARL". The "SUPEARL" pearls, which are even better and rarer than the "GRANPEARL", are the best of the best and have been carefully selected. Both "SUPEARL" and "GRANPEARL" are pearls of the highest quality.
Many customers that purchase pearls for the first time do not have a complete concept of the lustre of pearls. When I ask customers what quality pearls they want, they will answer "strong light", "extremely strong lustre", "aurora" and "tennyo". In fact, most customers have no accurate concept and distinguishing methods of the strength of pearl lustre.
There are various prices for pearls, even in the same size, with different luster, different blemishes, and different varieties. Prices are all very different. Before you ask for the price, please let me know the pearl type (freshwater/South Sea), size (7-7.5 mm/10-11 mm), acceptable blemishes (blemishes/slightly blemished/very slightly blemished), and luster. It is best to tell what style it is used for, earrings or pendants.
The difference between the quality of strands and loose pearls
The quality of pearls is generally judged on four aspects: size, luster, shape, and flaws. The size and luster standards of the necklace and the loose pearls is the same, the difference is shape and flaws.
