No, but they will eat diamonds.
Goats are actually very picky eaters. They are very curious animals and will use their mouths to learn about an interesting object. They like the taste of metal, particularly copper. (Copper is an important nutrient for goats, so I suppose they will seek it out.) They nibble on the metal buttons and pull tabs of our clothes, pull the keys out of the ignition of farm machinery, and especially like to get hold of my wedding rings. One lucky goat worked loose a small diamond from the band and swallowed it.
The jeweler is $300 richer and I’m more careful in the barnyard.
