Dyed Pink Agate

Silicon Dioxide (SiO2) - variety Chalcedony

Rock Type: mineral

Dyed Pink Agate

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.
