| I would buy one of Dr Tom's pearls displaying water- specifically the one shaped like a diamond with a roundish shaped top half. It shows water all the way around the edge. It is part of a lot, so my chance of getting it is zilch-- so my motto: "If not, that, then better than that".
I found a slightly blurry picture of it. the more pointed side is up. From 5pm to 8pm it shows the translucency. The top half shows the nacre. As I rotate it, the translucency would stay on the bottom and the nacre would con tinue to be seen on the top.
Just in case anyone is interested: Nacre is made of "aragonite platelets, which usually have a hexagonal shape, ... embedded within an organic matrix" (Strack 2006, p121) Sometimes the organic matrix (called conchiolin) allows the edges to turn translucent and the aragonite platlets become prisms.
Although people have used the term "water" here before, nothing seen on this forum before exhibits "water" as it was used by bygone natural pearl experts like Tavernier. Sorry my pictures aren't better, but if I should ever get another chance to see such a pearl, I will take many more photos.
