What we say in cases like this is "the house doesn't lose anything". Although it could mean a close analysis of the content of your vacuum or your garbage

One time I thought I had lost my mom's sapphire and diamon ring. It was a very elegant art deco piece and she gave it to me after it didn't fit her anymore. I searched for two days all my apartment (and it was MUCH smaller than the place we're in today) and finally found it lying openly on a magazin where it mixed in the pictures and text.

I wish you that much luck as well!

I wonder if you searched with a light in the dark whether it would reflect better?
