A 15.5" necklace using 4mm black glass beads, 6mm black agate beads, and black obsidian chips. The agate is streaked with soft brown tones. The crucifix and centerpiece are sterling silver, the beads are strung with stainless steel pins and finished with a platinum-plated clasp. Matching bracelet and earrings are available. Both necklace and earrings come with platinum-plated extension chains.
Both the agate and the obsidian are natural semiprecious gemstones and have not been dyed or color-treated.
UNDERSTAND WHAT YOU WEAR:
"Agate is a microcrystalline variety of silica, chiefly chalcedony, characterised by its fineness of grain and brightness of color. Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks." (Wikipedia)
"Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock.
It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth. Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows, where the chemical composition (high silica content) induces a high viscosity and polymerization degree of the lava. The inhibition of atomic diffusion through this highly viscous and polymerized lava explains the lack of crystal growth. Obsidian is hard and brittle; it therefore fractures with very sharp edges, which had been used in the past in cutting and piercing tools, and has been used experimentally as surgical scalpel blades."
