I am told that industry standard dictates that an 8-9mm pearl would
range from 8.0 to 8.9mm and a 9-10mm pearl would range from 9.0mm to
9.9mm and so fourth.
Also an 8 to 11mm strand of pearls would consist of pearls that
range from 8.0 to 10.9mm. Is this the industry standard? If I sell a
strand to my customer and say that it is 8 to 11mm, shouldn’t there
be at least one pearl that measures 11mm or more? If I bought a
strand and was told it was 8-11mm and then had it appraised and the
appraisal stated that it was 8-10mm with pearls ranging from
8.0-10.9, I would feel that I had been lied to. I know that pearls
are not as standardized as diamonds, but this practice does not rest
well with me. Please tell me what is most common in the industry.
