Max, I've heard what I would phoneticise as 'jewry'. Given your weird and wonderful Zild (whaddya mean no diphthong in rain?!?), this may be the same thing.

As for the jury, on the evidence so far it rules that your jewellery is quite clearly hot and you have no legal right to it. Please submit it to me for safekeeping until the rightful owner can be ascertained!
