Excellent suggestion lilliefuzzysocks
Again, that FW pearl necklace and a PP Akoya necklace...pears and apples to me! If they had the same sized pearls, same grade, same shape, same length...same ALL, then it is a clear and direct comparison.
So, for the sake a better comparison let me use this necklace:
7.5-8.0 mm 16 Inch AAA White Freshwater Pearl Necklace (pearlparadise.com)
Same length, same pearl type, overall larger pearls (not the central one which is larger on the American Pearl site), same grade (up for discussion, of course) and you have to pay $275 dollars vs $265... I would say this last pearl necklace is cheaper (by $10 dollars) because you are getting
more, but it really comes down to you to say the last word.
Now, if I were to compare this second necklace with an equal Akoya necklace (same traits), such as this one:
White Japanese Akoya Pearl Necklace | 7.5-8.0 mm 16 Inches | AAA (pearlparadise.com)
You will be paying $1,815 which is quite a difference from the freshwater pearl necklaces...again these are Akoya, smaller production, "brand name", perfectly round, "classic", etc...you pay more for these things. If it were a Cortez Pearl necklace (same traits, except colors of course) you would probably pay up to $8,000 dollars and this would be a fair price.
