In the technical terms of abalone, "several abalones" are used to describe how many abalones are contained in every 500g (or a catty according to the traditional saying). 10 abalone means that there are 10 abalone per 500g, and the average weight of each abalone is about 50g. Eight abalones means eight abalones per 500 grams, and the average weight of each abalone will be closer to about 62.5 grams. ..
Eight abalones are bigger and heavier than 10 abalone. Correspondingly, eight abalones are regarded as higher-grade and more precious food because of their large size and small quantity, and the market price will be higher than that of 10 abalone.
