Probably not the necklace? She already knew that Amano had forgotten it at another girl's place, so it wouldn't make sense to assume she's there just because the necklace is.

Chiwa has no idea that Yuhi left the necklace at Sakurako's apartment. When asked by Chiwa about the missing necklace Yuhi's only response was "Just a change of pace...maybe?" So, she might just assume that Yuhi decided not to wear the necklace that day. In fact, for Chiwa to tag an item of Yuhi's, she would've picked an item she would be certain Yuhi would have on her at all times. Considering she noted that Yuhi didn't take the necklace off previously even during sex, it's possible it was the chosen item as it would've been seen as the safest bet at the time.

Which leads to an issue, since the necklace always seeming to be in Sakurako's apartment is giving the impression that Yuhi's with Sakurako even more than she actually is, which is further driving Chiwa's anger.

I'm assuming Chiwa secretly put a tracking app into Yuhi's phone. The story seems to be making Yuhi's other sex friends into toxic people so that she'll eventually dump them all in favor of Sakurako.

Also, it seems like Yuhi's backstory is a classic case of grooming, where an older girl seduced her and then dumped her, causing her to seek casual sex instead of romance. The necklace is Yuhi's "collar" from that older girl. So, the plot is likely going to be Yuhi getting over her past heartbreak and forming a committed relationship with Sakurako.

she clearly wants an exclusive relationship with amano despite claiming otherwise but amano doesnt want that and that doesnt seem likely to change

The fact that the series has been told almost entirely from MC's view so far makes me think that there's more going on with Amano than meets the eye. So far basically every character is lying and putting up a front to deal with their insecurities, including Sakurako and both of her friends. Amano's playgirl persona is also likely at least partially fake and used as a coping mechanism. For example, she fiddled with her necklace (which she lied about not being important and likely about who gave it to her) when she said she didn't want a girlfriend. She might have some past relationship trauma that's causing her to reject committed relationships.

Either she'll eventually warm up to Sakurako enough to try for a committed relationship on her own, or her playgirl ways will eventually blow up in her face somehow, making it impossible to continue that lifestyle. For example, if the story decides to paint Amano's other friends with benefits as manipulative enablers that bring out her worst traits. And that would ditch Amano the minute she wasn't a convenient hookup for them anymore.
