pearlescence
purveyor of pearls UK/EU
It's amazing how quickly you can do a rough conversion in your head by the end of a shopping trip. I thought I was doing okay with USD, GBP, HKD and now you through yen and mommes into my head!
It can be daunting pricing out lots that are priced in yen and by momme. Dividing the number of pearls by the momme weight tells you the average size of the lot. Then you check the current exchange rate to get the list price for the average size. It's not too bad with a graded, separated lot. But when the lots are mixed, it's really difficult.
