Biggest sized pipi I've ever held!! Over 7mm and excellent quality. Usually the bigger sized pearls out of pipis have fair to poor surface quality and luster. 7mm is very large for the species. Strack states the average size for the species is 4-5mm but that information is outdated and what I've seen is the average size is 3-4mm. This is the most common size, with many more on the lower end of the range. It'll be interesting to see what climate change will do to average pearl sizes. My expectation based on my biological understanding is that we'll see more smaller pearls more frequently with the current average becoming less numerous. That's of course if the species doesn't die off.
