Pattye, not to worry with regard to you note, I appreciate you input. I'm considering in buying nr2. Just trying to figure out if it's real. Nr1 comes with a loose certificate, nr1 comes with an authentic red mikimoto box. I noticed the differences that you mentioned also. But although pictures are not great it seems awkward to see 2 almost identical bracelets of mikimoto. That would suggest that one is fake, disregarding the explanations mentioned by yourself.
On the other hand if one is fake it would not be a logical choice to fake this specific design imo. I think that there are more easy designs to fake then the ones above. Would love to hear your take on that.
Furthermore, would love to hear what the community thinks such a bracelet is worth. Just fyi, there is a 1200 USD price difference between them as they are listed at the moment. With nr2 as the relative cheap one, priced at 600 USD
