Where items are approximately spherical the size refers to their diameter. Where items are long and thin (such as crystal or blade shapes) or any other shape, then the size refers to their largest dimension. It is important to see the pictures to know exactly what the appearance is. Our pictures do not showcase the best, they are as realistic as possible and include a R1 coin to demonstrate the actual size.
A 500g pack will typically have 14 or 15 stones but this may vary with actual average stone size.
Mookaite according to a geologist. You may, however, be sorry you asked. (From: www.mindat.org/min-27597.html)
The term 'Mookaite' is an unofficial, locally coined name for a silicified porcelanite which forms in the weathering profile of a geological formation known as Windalia Radiolarite (WR), a Lower Cretaceous siltstone that outcrops over much of the Carnarvon Basin in Western Australia. Named after Mooka Station on which it was found.
From a strictly geological perspective however, Mookaite is best defined as a silicified type of Windalia Radiolarite whose silification is opaline to chalcedonic.
