As far as I know, the only carver to work with a specific farmer is Chi, from Galatea. That because its beads are special, but Chi needs also a very thick layer of nacre. All of that is possible in case of big productions, I can't ask anything similar according to my own very little use.
I regret this new rule, because the last was the only one to work for the best pearl quality, in all the pearl's world. Moreover, I can't understand the tahitian farmers meaning, when they have been recently damaged by a hard oversupply crisis. If they think to feel better by reducing the cost of their production with a lowered quality, that's a strange calculation... except if purchasers agree that, as they have agreed tomatos loosing all their tast, but perfectly red, and that for the same price... And then, this management allows to junk these tomatos, also, if their number is higher than the need.
Beside, in this way, all the pearls will be perfectly round, now, exactly like their bead... for the same price than before, one more time.
