Yarzhemskiite
Yarzhemskiite is a rare borate mineral with the chemical formula K[B5O7(OH)2]·H2O, composed of potassium, boron, oxygen, hydroxide, and water. It crystallizes in the monoclinic system and is classified as a borate mineral. This mineral is notable for its unique chemical composition, which includes a complex borate anion structure. Yarzhemskiite typically exhibits a vitreous luster and is colorless or pale in appearance. Its physical properties include a relatively low hardness and a moderate density, though specific values are not provided. As a monoclinic mineral, it may display prismatic or tabular crystal habits.

Its physical properties include a relatively low hardness and a moderate density, though specific values are not provided. As a monoclinic mineral, it may display prismatic or tabular crystal habits.
How to recognize it
Yarzhemskiite can be identified through its monoclinic crystal system and its chemical composition, which includes potassium and borate. Its colorless to pale color and vitreous luster are key visual indicators. Due to the lack of specific hardness or density values, identification may rely on chemical analysis and crystallographic data. It may be confused with other borate minerals that share similar physical characteristics but differ in chemical composition.
