Pinctada Maculata (Pipi) Pearls

Very interesting, could you by any chance take the exact mass of a round pearl as well as diameter? grams for the mass and millimeters for the diameter would be great. As to be precise you might be able to take a mass up to 0.001 grams if you go to a Jeweler when you go back to Paris.
I am curious about the composition of the pearl.
 
average size

Round 5.1 mm = 0.23 g
0.12 g = 3.9 mm
3.1 mm = 0.09 g
0.03 g = 2.6 mm

Oval: 2.5 mm = 0.08 g

button: 3.1 mm = 0.16 g
Color button: 4.1 mm = 0.17 g

Baroque: 3.2 mm = 0.12 g

Sorry for the delay just arrived from the province.
mmmh, the density is not constant, the above mentioned data for the round gave ρ∆ -10.2% +60.8% I think it may come from the accuracy of the tools used (caliper and weighing scale)
This said thank you very much for the information, the ρ of Pinctada maxima is roughly only 76% that of Pinctada maculata.

Please recheck if this measurement is correct (maybe a typo...)
3.1 mm = 0.09 g the mass is really high, shouldn't it be closer to 0.06?

bonjour Cyril
yes sorry it is well: 3.1mm = 0.6 g
woww :)
