暂无分享,去创建一个
Pearls have a premium on quality. The quality
differences ate so subtle and discrete that even professionals
in the pearl trade can make wrong judgements.

by weight and, on the other, by the quality of individual
pearls. Being a biological product, not coming trom
the assembly line of a factory, individual variations are
infinitely large. The secretion of the mantle or the
pearl-sac which leads to the formation of the pearl may
be organic or inorganic or their combination with unpredictable
variations in structure and composition
and the product may range from the finest to the trash,
ever under the highest possible human control. Therefore,
it is opt in this paper to consider the factors that
contribute to successful production and to the quality
of cultured pearls.
