Mesolite
A variety of Minerals
What is Mesolite?
Mesolite has a very unique shape, forming in long, almost thread-like crystals. Being made of calcium, sodium, and other soft elements, they are incredibly brittle. Large specimens have very hefty price tags and are titled by some as one of the mineral world's most visually attractive offerings!
Uses & Applications
Mesolite is sometimes used as a chemical filter, as its molecular structure makes it a natural "sieve" for small molecules. It does not have any other practical uses, and is rarely a gemstone for jewelry or mineral collections, due to its fragility and the rarity of large crystals.
Market Value Factors
Pricing varies for every rock and mineral, so use these universal factors to gauge Mesolite before comparing listings or appraisals.
Size & Weight
Larger, intact specimens usually command higher prices.
Rarity & Demand
Scarce material or popular varieties sell at a premium.
Condition & Finish
Chips, repairs, and heavy wear lower value; clean prep helps.
Treatment & Provenance
Untreated specimens with documented locality are prized.

Key Characteristics
Formation of Mesolite
It was first described in 1816 for an occurrence in the Cyclopean Islands near Catania, Sicily. From the Greek mesos, "middle", as its composition lies between natrolite and scolecite. Like other zeolites, mesolite occurs as void fillings in amygdaloidal basalt also in andesites and hydrothermal veins.
