Pink Flower Agate
Quartz (Variety: Agate / Chalcedony) with Plume Inclusions · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal / Microcrystalline Hexagonal; occurs in massive or nodular habits, here polished as a sphere.
Mineral Group
Silicates (Subgroup: Tectosilicates / Quartz Group)
Chemical Formula
SiO2 (Silicon Dioxide) with Aluminum, Iron, Manganese, and Calcium inclusions
Formation Process
Hydrothermal formation where silica-rich fluids deposit in volcanic rock voids (vesicles), with mineral inclusions crystallizing into flower-like plumes.
About This Crystal
An opaque to translucent pinkish-brown sphere with visible creamy-white or light pink 'flower' or plume inclusions. It has a vitreous to waxy luster and a smooth polished finish.

Optical Properties
Refractive Index: 1.530–1.543; Birefringence: Up to 0.004; Optical Sign: Uniaxial Positive; Non-pleochroic; Singly to doubly refractive microcrystals.
Hardness & Durability
Origin Region
Primarily Madagascar; found in volcanic basalt cavities.
Hardness & Durability
Mohs Hardness: 6.5–7; Excellent durability and toughness as it is a microcrystalline quartz; suitable for all jewelry types and decorative handling.
Care & Maintenance
Wash with warm soapy water and a soft brush; avoid harsh chemicals and hydrofluoric acid; safe for ultrasonic cleaning if no fractures are present.
Rarity & Value
Common to Uncommon; Value is based on the aesthetic arrangement of 'flowers' and color saturation; usually priced between $5 to $50 for small spheres and specimens.
Special Characteristics
Features 3D plume-like inclusions resembling cherry blossoms or flowers, caused by minerals like hematite or manganese within the chalcedony matrix.
Lore & History
Discovered relatively recently in Madagascar; traditionally associated with the Heart and Base chakras; symbolized as a stone of growth, self-actualization, and 'blooming' into one's potential.
