Likely rose quartz or quartz-rich stone
Quartz, silicon dioxide (SiO₂); pink coloration may reflect trace iron, titanium, or inclusions
AI-generated identification · may be incorrectPale pink to tan, translucent, with a glassy-to-waxy luster and irregular conchoidal fracture visible on the broken surfaces. Quartz has Mohs hardness 7, no cleavage, trigonal crystal structure, and specific gravity about 2.65.

Physical properties
Pale pink to tan, translucent, with a glassy-to-waxy luster and irregular conchoidal fracture visible on the broken surfaces. Quartz has Mohs hardness 7, no cleavage, trigonal crystal structure, and specific gravity about 2.65.
Formation & geological history
Forms mainly in silica-rich igneous and hydrothermal veins, or as grains in metamorphic rocks; individual formation ages vary widely from Precambrian to recent geological settings.
Uses & applications
Common quartz is used in glass, ceramics, abrasives, electronics, and construction; attractive pink material is used for carvings, cabochons, and inexpensive jewelry.
Geological facts
The photograph is not sufficient to distinguish rose quartz from pink chalcedony, feldspar, or a coated/processed fragment. A streak test, hardness test, and examination of crystal or cleavage features would improve identification.
Field identification & locations
Look for hardness sufficient to scratch ordinary glass, lack of cleavage, and conchoidal fracture; rose quartz commonly occurs in Brazil, Madagascar, India, and the United States. Avoid destructive testing if the specimen may be valuable.
