When you are in the editor (like where you see what items you have that you can place) check out the icons on the top right of the window. Find the one for retrieving items, and stand near that chandelier. Find the chandelier, if you have more than one in your house - use the direction arrows it shows along with the distance to the item to ensure you are retrieving the correct one. Then I believe you just need to click on that item in the list (if not, hover over it and I'm sure it will tell you to keybind on the bottom of your screen). This will put the item in your inventory
Not in game either, so instructions aren't perfect, but should give you the right direction to get your chandelier back.
