Ame, you seem to have a string of bad luck with your jewellery.
I can understand why Crystallina (was that the name?) said what she did, to an outsider who doesn't know your story, it just seems like you've created thread after thread about problems with your rings. I'm one of those who doesn't pay too much attention to such fine detail, perhaps that's why she said to just take a step back and try and enjoy your jewellery.
But if you have paid so much for it, you have the right to expect that they don't come back to you with a shoddy ring! And if you have OCD and if you know that the fault is there ... it is very hard to ignore it! I don't know why anyone would remove trademarks, but it sounds very careless and thoughtless! I hope the day comes that you have your perfect rings at last. Sending you good luck!!
