Origin and History

Lalvarit (or lalvarite from Russian Лалварит) is not a mineral name recognized by any official organization. Due to the uniqueness of the rocks of the Alaverdi ore region, referred to as “Ringing tuffs,” their limited distribution, and the absence of similar formations both outside the region and in Armenia as a whole, it is expedient to call them lalvarit—one of the formations found in the large volcanic structure of Mount Lalvar. These rocks are andesite in composition characterized by great freshness in appearance, which can be easily distinguished from all volcanic rocks of the region.

Andesite is an extrusive volcanic rock of intermediate composition between basalt and rhyolite. Andesite is a fine-grained igneous rock that is intermediate in its silica content and low in alkali metals. It is usually grey in appearance and composed of large amounts of silica.


Violet Grey Lalvarit is from deposits in the Lori Province of Armenia, from lava flows of the Alaverdi ore region near Mount Lalvar.

Permanence and Compatibility

Based on the colorants, iron and manganese oxides, this pigment has broad compatibility and permanence with all media. Iron and manganese oxides are very lightfast and stable outdoors and have excellent weatherfastness.

Oil Absorption and Grinding

The oil absorption value for Violet Grey Lalvarit is 32. This means 32 grams or milliliters (approx.) of linseed oil is required to form a coherent paste for every 100 grams of pigment. Violet Grey Lalvarit has a Mohs hardness of 4, which gives it the same abrasiveness as marble. This pigment is easy to grind into both waterborne and oil paint.


Lalvarit is not considered hazardous; however, care should be exercised when handling the pigment to avoid inhaling or ingesting the powder.
