But again, it's not the necklace that is special. It's the two different characters who are.
This isn't a future swastika, a surefire conversation piece in any company. It's the company that matters: Picard the vision guy, and Narek the suspicious creep. We can tell that these people are special exactly because they pay attention to the jewelry when nobody else does. Heck, not even the wearers themselves think much of the motif they wear!
I really don't see how there could be an issue with this. Common or rare, this exact necklace is how you tell an advanced android from ordinary folks. Narek must know that, which is the only reason he pays attention to it. And Picard is at least subconsciously suspecting it.

As I said before the bigger thing is that for us, watching the show, we have to be in it with the characters, see things through them, and the show should be doing what it can to make that process easier for us and we're supposed to be behind this with Picard and suspicious of Not!DiscoverySpock. So if Picard's in danger we should be worried, if N!DS is in danger we should be happy. If Picard is suspicious things we should be too.
So when our protagonist character see a necklace and goes, "That's very unusual!" and then we see it we shouldn't be sitting here at home going, "Huh? There's nothing remarkable about that thing at all. My kid bought something just like that out of one of those gumball-machine things in the Walmart breezeway last week."
Looking at a closer-up picture of it (they're selling it on-line, linking it to the series, because of course they are) the most "unusual" thing about it beyond it just being two interlocking circles is that the ring of the circles isn't consistent, it's got kind of a wider edge to it, sort of like the ring around an eclipse at 95% or something. But other than maybe that, it's an unremarkable design and not something anyone should take notice of, beyond knowing what it means which N!DS may know, but Picard doesn't.
And even with N!DS pointing it out, again, there shouldn't be anything remarkable about it because it's a perfectly normal-looking piece of jewelry that there's probably billions of people wearing who have no idea about the cloning thing whatsoever.
If your character is going to go, "That's very unusual!" it better be pretty fucking unusual
for us because we're the ones watching the show and the ones who have to buy into things.
And why is it the symbol for the cloning thing anyway? They need to get a new PR guy because he phoned that thing in.
If this cloning thing was/is supposed to be so unique, remarkable, the "grand slam" as the doctor puts it their symbol should represent that and not be something someone wouldn't give a second thought to.
That's just it, though: if it were eye-catching, this would defeat the purpose, because eyes catching it would not be anything out of the ordinary then.
... Huh?! Eye catching is the very definition of "out of the ordinary." Ordinary things are dismissed, glossed over, you don't think about them. They're don't catch your eye. But something that's
unordinary stands out it catches your eye.
