I know this is an old post but pearls and MOP become more alive when worn.Oh no
I’ve had a different experience; I bought my WG MOP 5 motif about 3 years ago, wore it almost everyday as a bracelet for about 2 years for about 10-12hrs/day for work, out and about etc, and now it is a part of my necklace of 5 motifs. And it still has a beautiful shine and luster to it, esp after using the polishing cloth
