'Polished' in the Bible

Now as far as I am able, I have made ready what is needed for the house of my God; the gold for the things of gold, and the silver for the silver things, and the brass for the brass things, iron for the things of iron, and wood for the things of wood; beryls and jewels to be framed, and stones of different colours for ornament; all sorts of stones of great price, and polished building-stone, as much as is needed and more.
