Makes me think of this part of Lord of the Rings about the Glittering Caves

Caves! The Caverns of Helm’s Deep! Happy was the chance that drove me there! It makes me weep to leave them.’

…

‘No, you do not understand,’ said Gimli. ‘No dwarf could be unmoved by such loveliness. None of Durin’s race would mine those caves for stones or ore, not if diamonds and gold could be got there. Do you cut down groves of blossoming trees in the springtime for firewood? We would tend these glades of flowering stone, not quarry them. With cautious skill, tap by tap – a small chip of rock and no more, perhaps, in a whole anxious day – so we could work, and as the years went by, we should open up new ways, and display far chambers that are still dark, glimpsed only as a void beyond fissures in the rock. And lights, Legolas! We should make lights, such lamps as once shone in Khazad-dûm; and when we wished we would drive away the night that has lain there since the hills were made; and when we desired rest, we would let the night return.’

Gimli’s description of them to Legolas was reportedly one of the few times that a dwarf has bested an elf with words; Legolas was left speechless after visiting them.
