diamond in a goat's ass 

Someplace or something very beautiful hidden or masked by something ugly.

Their studio was in the middle of a run-down warehouse but when you got inside it just opened up into this amazing space... it's like a diamond in a goat's ass.

Shines like a diamond in a goat's ass 

To say: "Shines like a diamond in a goat's ass" is to provide high praise for something or someone. A harsh term, it is often used by men in the working trades. A star baseball player on a mediocre team could be said to "shine like a diamond in a goat's ass." Often, the phrase is used as a compliment for a really nice car or motorcycle. Ironically, it would not be appropriate to compliment a diamond ring or other jewelry with this phrase. (Body piercings excepted.)

1. That new chrome on your Harley-Davidson shines like a diamond in a goat's ass!
2. The ghost flames on your pickup truck make it shine like a diamond in a goat's ass.
3. Inappropriate usage: "Your engagement ring shines like a diamond in a goat's ass!" (That might get you bitch-slapped.)
