"Turning love to lust/ Grinding pearls to dust." 
This line was inscribed in my memory and I don't remember where i've
taken it from. Any ideas? It might not be accurate.

There are some very similar lyrics in "The Ambitions Are," by The Golden Palominos:

"...so you drive your dead body home at night 
 and when you sleep the angels kisses are mercury 
 mercury 

 breaking love into lust 
 grinding pearls into dust..."

If this is the song you're thinking of, I'll be glad to post it as
your official answer. If not, a few more lyrics would be helpful.
