i got this bracelet in the mail today and its a 8" 3mm curb bracelet and weighs 4.4g its marked on both ends with a p in side a house? and on the reverse side it says either 920 or 925 italy i can make out if its a 5 or 0 its also marked on the c clasp i can see this one for sure it says 920 clear as day may question is does the p mean platinum or is it just a makers mark or trade mark?
