How to handle a possible theft?

Ask him is he saw it, tell him it’s missing and see how he responds.

@DWW25921 He called not to long ago, and asked if there was any problem and he never responds like that.

It’s a shame that folks have to worry about this sort of thing… Maybe you should ask if he moved it?

@zander101 He called you, just to ask whether there were any problems?

Without actual proof you need to tread really softly here.
You have no facts to go on and making up stories in your head about anothers guilt is not acceptable.
For all you know it fell off the table, is under a throw rug, the cat swatted off the table and under the fridge, you or someone else picked it up and you forgot…etc. etc.
It may seem suspicious but you need to be very careful before accusing someone.

Did this person call and ask about any problems because you were acting funny around them when they were at your house?
If you were acting weird they might just be picking up the weird vibes and wondering if you are upset about something.
Is this person trustworthy to begin with?
Are they broke, in dire financial straights, drug users, etc.?

If so then maybe you are correct, but still…tread lightly I say.

write it off as a learning curve and never have him in your home again.

Are you absolutely certain it was not moved by someone else?

@Coloma I appreciate the response however I did not speak to him personally a family member did via phone and the response was out of character for him, the necklace itself was left on the table, nobody was up other than me, him, and my other family member, nobody was acting weird around anyone cause by the time it was discovered missing he had already left. The other family member knew of the necklace and they said that they had nothing to do with it and it’s been in my possession for 5 + years.

@zander101 Understood, just playing devils advocate. It is also a terrible feeling to be accused of something you didn’t do. Good luck sorting things out.

@Coloma I understand, there’s always 2 sides of every story, the necklace itself has sentimental value to me and for it to go out like that pains in words I can’t even express, will see what happens.

The problem is that you don’t know what happened to your necklace and to accuse someone without proof is not the right thing to do. I have heard so many stories where the person is 99.9% sure that someone else did or said something, only to find out later that it wasn’t true. Don’t go there.

I am sorry about your necklace though.
