Zeolite with Celadonite (and Apophyllite/Stilbite)
Silicate group mineral assemblage featuring Celadonite and Zeolite species · Mineral Specimen / Rough Matrix
Crystal System
Monoclinic (Celadonite) and Orthorhombic/Tetragonal (Zeolite inclusions/host)
Mineral Group
Silicates (Phyllosilicates and Tectosilicates)
Chemical Formula
K(Mg,Fe2+)(Fe3+,Al)Si4O10(OH)2 (Celadonite) with various hydrated aluminosilicates
Formation Process
Hydrothermal precipitation within volcanic basalt cavities (vesicles) and gas bubbles
About This Crystal
A rough volcanic matrix specimen featuring a distinctive dull, earthy green coating of Celadonite over crystalline Zeolite structures. Small white to translucent druzy sparkles indicate micro-crystals of Apophyllite or Quartz. The reverse side shows the reddish-brown weathered basaltic host rock.
Physical Characteristics
Color: Sage green to olive and reddish-brown; Streak: Light green or white; Luster: Pearly to earthy/dull; Transparency: Opaque to translucent; Specific Gravity: 2.1 - 2.8.
Optical Properties
Mostly opaque in mass; micro-crystals may show vitreous luster and weak birefringence; no significant dispersion or play of color.
Hardness & Durability
Origin Region
Deccan Traps, India (notably Jalgaon or Nasik regions)
Hardness & Durability
Mohs Scale 2 - 5.5; generally fragile and soft; low toughness; susceptible to scratching and crumbling.
Care & Maintenance
Clean only with dry soft brush or warm soapy water; avoid ultrasonic cleaners and harsh chemicals; store away from direct sunlight to prevent dehydration of zeolite minerals.
Rarity & Value
Common to abundant; low to moderate value depending on crystallization; primarily valued as a geographical representative specimen.
Special Characteristics
Features a 'green earth' pigment coating (Celadonite) over volcanic secondary minerals; may show subtle green fluorescence under shortwave UV if certain inclusions are present.
Lore & History
Historically used as 'Terra Verte' (Green Earth) pigment in European painting; traditionally associated with grounding, connection to nature, and heart chakra alignment in holistic practices.
