The opal formed in rocks such as sandstone, ironstone, and petrified wood. When hydrated silica replaced rounded organic matter of tree roots and such, it occasionally formed a pipe opal of superior vibrancy and brightness.

We also use a 100mm Macro Lens to take pictures, this helps capture every detail in the stone, which sometimes is not visible to the common eye.

Please note : Not all scales are made the same, so there maybe slight variation is size and weight.
