Flower Agate
Chalcedony var. Agate (with Opaque Inclusions) · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal (Microcrystalline); This specimen is cut into a polished hexagonal tower/obelisk with a prismatic habit.
Mineral Group
Silicates (Tectosilicate group, Quartz family)
Chemical Formula
SiO2 (Silicon Dioxide) with Ferruginous and Clay mineral inclusions
Formation Process
Hydrothermal/Sedimentary; formed by the precipitation of silica from groundwater into cavities of volcanic rock, where plumose inclusions of minerals like hematite create the flower-like patterns.
About This Crystal
Translucent to semi-opaque chalcedony with creamy, pink, or white opaque 'flower' or plume-like inclusions. Features a vitreous to waxy luster and a polished, smooth surface.
Physical Characteristics
Color: Pale grayish-pink base with white/peach inclusions. Streak: White. Cleavage: None. Fracture: Conchoidal. Specific Gravity: 2.58–2.64. Fluorescence: Often inert but can show weak yellow-green under UV.
Optical Properties
Refractive Index: 1.530–1.543. Birefringence: Up to 0.004. Optical Character: Uniaxial positive. Pleochroism: None.
Hardness & Durability
Origin Region
Primarily Madagascar; typically found in volcanic rock cavities or sedimentary deposits.
Hardness & Durability
Mohs Hardness: 6.5–7. Good toughness and durability; suitable for most jewelry and decorative uses.
Care & Maintenance
Clean with warm soapy water and a soft brush. Avoid ultrasonic cleaners if the stone has internal fractures. Store away from harder stones like Sapphire or Diamond.
Rarity & Value
Common; value is determined by the clarity of the 'shards' or 'flowers' and the transparency of the host agate. Generally affordable ($10-$50 for standard towers).
Special Characteristics
Features 'Plume' or 'Flowering' inclusions that resemble cherry blossoms or seeds growing in the stone; occasionally contains small geode pockets of druzy quartz.
Lore & History
Discovered relatively recently in Madagascar (late 2010s). In modern crystal lore, it is associated with the Heart and Base chakras, symbolizing personal growth, 'blooming,' and reaching one's potential.
