I'm thinking of replacing the pearls with different gemstones as this is my engagement ring and I wear if every day. I read that this happens often with pearls, I wish I looked into them before deciding on what I wanted and I don't want to keep replacing the pearls.It looks like the nacre was thin on the akoya pearl, and peeled off. What you see is the shell bead nucleus underneath.
If you care enough about the ring to pay for repairs, you could have the pearl replaced with a small freshwater pearl instead, which has no bead inside. If you do that, I'd have both pearls replaced at the same time so they match.
Yes, I do remove it when I wash dishes/hands or shower. I'm assuming this happened because of work, or I just hit my hand on something. I'm quite disappointed that I'll have to change it up now as I've grown attached but it's better for to change the pearls than to not wear my ring every day as it's become an extension of my handI was going to ask if you wore this ring every day. It looks like you've worn the nacre right off the shell bead nucleus. The pearls have been loved to death (and I mean that in a nice way!).
Did you remove your ring for washing dishes and doing cleaning? If not, then the detergents and chemicals could have eaten away at the pearl nacre, too. There's a reason most engagement rings are diamonds or sapphires. They're the hardest stones. I wear my pearl rings on special occasions only, and remove them to wash my hands. I agree that you should replace the pearls with harder gemstones if you're going to wear the ring every day.
My aunt used to swim every day, and the chlorine in the the pool water disintegrated the gold alloy of her wedding ring. So it's not just pearls that are going to be dissolved by chemicals. Remove your rings when washing your hands or cleaning anything.
