To flesh out the setting, Middle-earth Role Playing introduces many new terms for stones.
Dirielong
Dirielong (S. “Gazing-rock”) is a Dwarven name for softer types of stone. These are again divided in two categories. The first category is “block-stones”, such as coloured marbles and wet-rocks (or limestone). The second is “slab-stones”, such as schist, flint and slate.[1]
Naurond
Naurond (S. “Fire-rock”) is the Dwarven term for igneous rocks, such as commonly found in Khazad-dûm. Examples are are granite, basalt and pumice.

Mirond
Mirond (S. “Jewel-rock”) is what the Dwarves call fine glasses and gemstones. Fenen (S. “Veils”) or Hidden Crystals are terms for glasses, while Maegelenath (S. “Sharp-stars”) or Bold Crystals are terms for gemstones.[1]
Laen
Laen (“Long Thread”) is the most notable of the glasses. It is as hard as diamond yet smooth, and enchanted state allows it to be moulded when cooled to very low temperatures. In its natural state it is black, but when worked it can be coloured or made clear. [1] Its name refers to its long crystal lattice structure.[2]
Ulgond
Ulgond is a liquid stone used extensively by the Gwaith-i-Mirdain. When poured into wooden moulds it will harden over time.[3]
