  • Locality + Mining Process

    Agate Creek, North QLD Australia
    Agate Creek is Australia’s most famous Agate location, known for its stunning range of Agate colours, shapes and patterns.
    Agate Creek is a public fossicking location accessed via 4WD in the dry season, and with a QLD fossicking licence. There you can find a variety of World-Class agate, Thunder eggs and Geodes filled with Quartz  crystals such as clear or Amethyst. Agate Creek has been a popular Fossicking location since it was established in 1995. To learn more about the Agate Creek Fossicking locations, visit
    To identify rough agate, look in corners of rivers or in pebble wash on the side of rivers. Use a torch to check for translucencey. Consider the shape as most agate is rounded to some degree as it occurs as a bubble. Shake the stone and listen for any rattling from inside, this could indicate a Geode! The best way to identify a rough agate is to look for surface marks, irregular fractures and waxiness. The surface of agate is pourous and can appear like tiny craters like a golfball. Remember, Agates found in creeks could be black on the outside from moss that has coated the stone and are not always easy to see!
  • Crystal Description

    Agate is identical to chalcedony in terms of composition and physical properties. They are both Silicon Dioxide crystals with the mineral composition SiO2. 
    Agate can be characterised as a Silicon Dioxide formation that displays patterned concentric banding and wild varieties of colour. When the patterns inside an agate are all straight lines, the stone is called “Onyx”, or when no patterning is visible it is called “Chalcedony” but both contain the same identical mineral composition as Agate.
    Agate occurs naturally as amygdales (gas bubbles that are filled) rising to the top of basaltic andesite lava flows. Amounts of silica with accompanying minerals (causing variations in colour and transparency) are despoited into the "Bubble" over time, causing layers of alternating colour. "Thunder Eggs" occur as spherulites (crystals grouping around a point) in rhyolitic lava.
    Grade is dependant on the banding, colour, transparency & shape. Agate is often dyed to enhance its colour, however this agates colour is 100% Natural and Untreated.
