Large Chalcedony Cave with Botryoidal growth


This product is the exact stone pictured.


This raw Chalcedony cave includes a deep pocket of botryoidal orange growth.  Its open cave face displays white and grey banding. Its exterior shows amazing growth patterns with a moon crator texture. 

 It was fossicked in Capella QLD and is in the raw form it was found in. This is a heavy and stunning raw specimen. 

  • Hardness + Care

    Chalcedony has a hardness of 6.5-7 and is pretty sturdy in a polished form, however, any specimens with crystal points should be protected as sometimes crystals become loose in their journey from underground to the surface, and can easily damage if dropped or handled roughly.

    Chalcedony can be cleaned with or submerged in water with no damage to the crystal. 

  • Locality + Mining Process

    Chalcedony occurs around the globe on almost every continent. Quartz or Silicon Dioxide crystals are the most commonly occurring minerals due to the abundance of the chemical elements Oxygen and Silicon from which it is made. Chalcedony can be found in more deposits than I could write, to see a full list visit

    The Chalcedony family includes many other stones that are individually named for their distinct colours or patterns. For example, any agate that does not contain concentric banding would be considered a Chalcedony. A bright green glowing variety of Chalcedony may be called Chrysoprase

  • Crystal Description

    Chalcedony, a globally widespread gemstone, captivates with its translucent beauty, showcasing hues from soft blues and greens to warm earth tones. This quartz variety forms in diverse environments, often in association with volcanic rocks and geodes, exhibiting intricate crystalline structures.

    Renowned for its aesthetic appeal, chalcedony is not just a decorative gem but also a versatile and utilitarian stone. Its moderate hardness allows for intricate carvings, making it a favored choice for ornamental pieces and amulets. Additionally, chalcedony's suitability for engravings and cameos adds to its artistic allure.

    Chalcedony contains the same physical make-up as many other stones. It is a SiO2 stone, which can take many names depending on which colours it displays:

    Agate - banded chalcedony
    Aventurine - sparkly green bloodstone - dark green + red
    Carnelian - red + translucent
    Chrysoprase - neon green
    Jasper - red, yellow, brown, black
    Onyx - solid black
    Sardonyx - brown and red banded
