Gimli and Galadriel

[thorondil]

He was definitely in love with her.

MLD-Grounds-Keeper-Willie says:

He must have thought, 'how could elves be so bad when they are this beautiful.' It might have made her seem even more beautiful. Galadriel might also seem more beautiful due to her elven ring, but that's besides the point.

She didn't need the ring.

From 77:

A sister they had, [the sons of Finarfin] Galadriel, most beautiful of all the house of Finwe; her hair was lit with gold as though it had caught in a mesh the radiance of Laurelin.

Gimli tells Legolas that he would even welcome a message from Galadriel speaking of his death. And when Gandalf the White delivers her message to him (calling him Lockbearer) he dances and sings.
