No but many of us here can answer pearl questions for you. What would you like to know?

P.S. If you think diamonds are confusing with four c's one of which is size, wait until you try to get an accurately graded strand of pearls.
Color
Orient (a sub catagory of color pearls, either have it or they don't.)
Clarity (blemishes)
Nacre thickness
Luster
Shape
Uniformity
Any of the above factors can have HUGE consequences to the price of the strand. You will not find GIA certificated strands being sold at a few percent over cost like you can with diamonds, rather you will find well graded strands being difficult to sell because the cost seems high in comparrison to poorly graded strands that are grossly overpriced if you only knew.
Pearls are very complex to grade and to price, but when they are beautiful they are REALLY beautiful. Be careful, but have fun!
