Diamond Chat

An extremely high level of conversation that engages, entertains and amazes the listener. Usually reserved for social events, but not exclusively so. Very valuable chat, comparable in worth and rarity to the precious stone. The opposite of sh*t chat.

“ How was your night out on Saturday?”
“ It was really good thanks. I thought it was going to be awful, but Handsome Baz was there and you always get guaranteed diamond chat with him.”
