Kiwi Jasper

I. The Metaphysical Reading

How the stone has been held.

Kiwi jasper is worked with as a stone of gentle beginning, held for people learning to enjoy small pleasures again after burnout or grief. Its speckled surface is said to remind the carrier that a whole life can be rebuilt from tiny dots of colour.

II. The Scientific Reading

What the lattice actually does.

"Kiwi jasper" is a trade name for a composite ornamental stone in which a pale quartz or feldspar matrix is peppered with black schorl tourmaline needles and pink manganoan zoisite (thulite). It is not a true jasper by strict mineralogy, but it takes a high polish and behaves like one in lapidary work. The name and marketing derive from the resemblance of the polished surface to the flesh of a kiwifruit.
