The manufacturing of a hard-stone dial is a complex and lengthy procedure involving cutting a perfectly intact stone into thin slices and then eventually fit them on the dial’s brass base. This technique often leads to damaging the stone and results in only a small number being actually used, with the vast majority of dials being discarded during the manufacturing process. Well preserved examples are therefore highly praised by collectors looking to complement their collection with exclusive examples.

Sodalite
The name sodalite is a compound word from Latin sodium and Greek lithos for stone and refers to its high sodium content. Sodalite was first found in the Ilímaussaq massif in the province of Kitaa (West Greenland) and described in 1812 by Thomas Thomson.
