Malayaite
A variety of Minerals
What is Malayaite?
Malayaite is a calcium tin silicate mineral with formula CaSnO[SiO4]. It is a member of the titanite group.
Market Value Factors
Pricing varies for every rock and mineral, so use these universal factors to gauge Malayaite 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
Characteristics of Malayaite
Malayaite exhibits anisotropy so it is doubly refractive and breaks up the light that travels through it into two distinct rays of different speeds. This mineral is known to have very high optical relief and has three indices of refraction. Since it is a monoclinic mineral, Malayaite exhibits two different colors under plane polarized light making it a pleochroic mineral. Malayaite is biaxial birefringent (trirefringent).
Formation of Malayaite
This mineral is generally found in tin-rich contact metamorphic skarn deposits. There is a possibility that malayaite is a hydrothermal altered form of cassiterite-quartz assemblage or some tin-bearing mineral. There have been specimens that were found with malayaite as a coating mineral on cassiterite.
