Chrysoprase is chalcedony—cryptocrystalline quartz—colored by trace nickel silicate dispersed through its microcrystalline structure

used in carved seals and amulets from ancient Egypt to the Mughal courts

The bead in this bracelet contains earth sourced from the Bell Rock formation in Sedona

Chalcedony is cryptocrystalline quartz—silicon dioxide built up in microscopic fibers rather than visible crystals

Sedona Red Rock Heart size:1.1"L x 1.4"W x 0.7"T Chrysoprase is chalcedony—cryptocrystalline quartz—colored bySedonas Permian sandstone, carved into a heart 270 million years of geology in a classic form. The red rock formations surrounding Sedona are principally the Schnebly Hill Formation a sequence of sandstones and mudstones laid down approximately 270280 million years ago in coastal and shallow marine environments. The iron content of those ancient sediments was exposed to oxygen as the sea retreated, oxidizing to hematite and staining the rock in tones
