Dyed Pink Agate
Silicon Dioxide (SiO2) - variety Chalcedony
Rock Type: mineral

Physical Properties
Hardness: 6.5-7 (Mohs scale); Color: Artificial neon pink (natural is likely grey/white); Luster: Waxy to vitreous; Crystal structure: Trigonal (microcrystalline); Cleavage: None; Specific Gravity: 2.60-2.65
Formation & Geological History
Agate forms as nodules in volcanic rocks or ancient lavas, where silica-rich groundwater fills gas bubbles (vesicles). This specific specimen has undergone a secondary human-led process of acid-treatment and dyeing to achieve the vibrant pink color.
Uses & Applications
Primarily used for decorative purposes, low-cost jewelry (beads, pendants), as a 'pocket stone' in metaphysical practices, and as a educational sample for beginners.
Geological Facts
Natural agate is rarely this vibrant pink; most 'neon' pink agates seen in shops are dyed. Because agate is porous, it absorbs chemical dyes well, a practice that dates back to the ancient Romans.
Field Identification & Locations
Identify by its waxy luster and often banded internal structure. In this case, the concentrated 'hot pink' color in cracks or circular bands indicates artificial dye. Common in rock shops globally.
