Overview

Vonsenite is a rare borate mineral with the chemical formula Fe²⁺2Fe³⁺O2(BO3). It belongs to the orthorhombic crystal system and is classified under the Strunz system as 6.AB.30. The mineral is characterized by a Mohs hardness of 5, a moderate density, and a vitreous luster. It typically exhibits a dark green to black color.

It is not commonly found in nature and is of interest primarily for its chemical composition and crystallographic properties.

Etymology

Vonsenite is named after Magnus Vonsen, a Norwegian mineralogist. The mineral was recognized and named in his honor, though no specific discovery year is provided in the facts.

How to recognize it

Vonsenite can be identified by its Mohs hardness of 5, which allows it to scratch glass but not quartz. It typically appears dark green to black in color and has a vitreous luster. Its streak is likely dark, though specific details are not provided. Due to its rarity and similarity to other dark-colored borate minerals, it may be confused with species such as uvarovite or other iron-rich borates. Careful analysis of its chemical composition and crystal system is necessary for accurate identification.

Trivia

Vonsenite is notable for its unique chemical composition, which includes both Fe²⁺ and Fe³⁺ ions in the same structure. It is a rare mineral, making it of interest to collectors and mineralogists. Additionally, its classification under the borate group highlights its chemical distinctiveness, as borate minerals are relatively uncommon in the Earth's crust.

Indicative prices

Vonsenite is a rare mineral and is not commonly traded as a gemstone or in jewelry. As such, there are no well-established price ranges. Specimens for collectors may vary by source and quality, but specific figures are scarce. If encountered in the market, prices likely depend on origin, clarity, and overall aesthetic appeal.
