Larmalstone or larmal was a type of expensive rock found only in the Roche asteroid field. Milky in color, it was used as a floor covering, as well as to produce statues and other furniture.
Han Solo and Leia Organa Solo had a larmalstone floor in the cul-de-sac leading to their Eastport apartment on Coruscant.
Admiral Nek Bwua'tu had a larmalstone bust of Admiral Ackbar aboard the Galactic Alliance ship Admiral Ackbar.
A priceless larmal-topped end table was present in the Queen Mother's Special Salon on Hapes. In 40 ABY, Leia Organa Solo had to restrain Han Solo from throwing it at a very annoying pendulum clock.
Polished larmalstone also graced some of the floors of the Hapan Embassy on Coruscant. The planet's New Jedi Temple contained a meeting chamber for the Jedi Council that bore larmalstone flooring.
