Way cool! Are we sure that's not Noreena by another name?

I googled the stone,
"Munjina Stoneā is from the Chichester Ranges in the Pilbara region of Western Australia, approx. 800 miles N. of the capital, Perth.
It occurs in the Jeerinah Formation which is part of the Fortescue Group in the Hamersley Basin. Age is late Archaean & was deposited between 2765 & 2687 million years ago That Cinnabar is really cool
Nice stuff!

I handled a slab of Munjina, and it is not quite as hard as Noreena. Also Noreena does nto have the dark areas. Generally Munjina can be more colrful.

The "cinnabar in quartz" to me looks a lot like a high grade plasma-agate with cinnabar, often as found from Clear Creek area in San Benito County, CA.
