Krutovite
A variety of Minerals
What is Krutovite?
Krutovite is a cubic nickel diarsenide with a chemical composition of NiAs2 and a sulfur content of 0.02-0.34 weight percent. Krutovite is composed of nickel and arsenic with trace to minor amounts of cobalt, iron, copper, sulfur, and antimony.
Market Value Factors
Pricing varies for every rock and mineral, so use these universal factors to gauge Krutovite 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 Krutovite
Krutovite is opaque grayish white paler then the color of nickel skutterudite. In reflected light the mineral has a vivid white with a rosy tint. It has a hardness of 5.5 on the Mohs scale and a metallic luster. No cleavage is observed. Krutovite has high degree of reflectance about 64.0-67.0% higher than known nickel arsenides and sulfarsenides. The spectrum of reflectance that occurs in krutovite has a wavelength range of 440-1100 and a minimum of 480-540 nm. The rose tint gives the small increase of reflectance in the violent and red parts of the spectrum.
Composition of Krutovite
Krutovite is from the family of the isometric-dipoloidal system (2/m3) and is known to have the same structure type as gersdorffite type P213. Krutovite and gersdorffite form a solid solution at a temperature of less than 300 °C (572 °F).
