The term "Black Silver" refers to 925/1000 silver that has been oxidized to make it dark grey. Black silver will develop a patina, the treatment will fade in places to reveal the natural shine of untreated silver.

The Mauna Loa collection is named after the world's largest volcano (Hawaii, USA). Mauna Loa, literally "Long Mountain", inspired Legion in its search for basaltic texture and in the choice of stones that seem to come from the deepest bowels of the Earth. Eroded yet raw lines are the DNA of this timeless, unisex collection.
