This trio is so special, it needs a formal introduction :
Rainbow Lattice Sunstone / / Gilalite in Quartz / / Snakeskin Stone
RARE AF Australian Rainbow Lattice Sunstone - a mouthful of confetti! This type of sunstone is only found in the Rainbow Serpent mine (Harts Range) in central Australia. It is a type of feldspar (same family as moonstone) which contains the aventurescence effect and the Schiller effect, aka sparkly freckles and a reflective haze, respectively. Hematite and magnetite are responsible for creating the crystallographically oriented inclusions, which look like micro confetti and twining lattice blades. Oxidization and geophysical wear and tear makes those inclusions look iridescent to our eyeballs!
Gilalite in Quartz is also known as Medusa Quartz and Paraiba Quartz, after the only mine in the world which it hails (Paraiba, Brazil). It appears in two different configurations ; the stone above contains the little bubble jellyfish formations, while the other variety shows furry icy flakes of the copper silicate mineral termed Gilalite.
Snakeskin stone is a fossilized stone found on the island of Madura, Indonesia. Despite its name, it is not in fact snake skin... the material is actually a fossil of the mouth palate of ancient wrasse fishes. Even some of today's wrasse species have hard grinding plates in their mouths that crumble coral and rock rubble to extract delicious algae.
