Orange mineral fragment, possibly citrine or iron-stained quartz
Quartz (SiO₂), tentatively iron-included quartz/citrine
AI-generated identification · may be incorrectSmall translucent orange-yellow fragment with vitreous luster; apparent uneven fracture and no clear crystal faces. Quartz hardness is Mohs 7, has no cleavage, hexagonal crystal structure, and specific gravity about 2.65. The image is too limited for confident identification.

Physical properties
Small translucent orange-yellow fragment with vitreous luster; apparent uneven fracture and no clear crystal faces. Quartz hardness is Mohs 7, has no cleavage, hexagonal crystal structure, and specific gravity about 2.65. The image is too limited for confident identification.
Formation & geological history
Quartz forms in igneous and hydrothermal veins, cavities, and sedimentary deposits; orange color may result from iron impurities or surface staining. Quartz is geologically widespread and can range from Precambrian to modern deposits.
Uses & applications
Used for glass, abrasives, electronics, and stonework; transparent, attractive pieces may be sold as citrine or decorative quartz. This fragment appears low-grade.
Geological facts
Natural citrine is relatively uncommon; much commercial “citrine” is heat-treated amethyst. Orange chalcedony, carnelian, feldspar, and resin or glass are plausible alternatives.
Field identification & locations
Near Townsville, Queensland, quartz and iron-stained silica are regionally plausible. Test for scratching glass, inspect for conchoidal fracture, and check that it does not scratch with a steel knife; definitive identification requires a clearer image, streak, hardness, and specific-gravity tests.
