This product is the exact stone pictured.
 
Authentic untreated slice of Agatised Jasper from Rosewood Ipswitch QLD. 
This specimen has a high-quality hand polish on one side and is left in its natural state on the sides and unpolished on the back face. It is a brown agatised jasper with a variety of colours through it, and an agatised white "river" pattern running from the centre to one edge. Inside the river are small druzy crystals that sparkle in the sun. 

  • Hardness + Care

    Agate has a hardness of 7 and is pretty sturdy, however this is a very unique specimen that deserves a special spot in your home where it can be admired. 

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

  • Locality + Mining Process

    Rosewood Ipswitch QLD

    This location was a private property that the owners fossicked some stones from and sent them in to be cut and polished. The location is now closed to fossicking, so these are from a limited one time collection.

    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.
