(Earring findings / Brass screw type) Jet is a gemstone that originates from organic matter, formed from ancient plants that accumulated as driftwood on the seabed during the Jurassic period, when dinosaurs ruled the Earth 180 million years ago, and fossilized over a long period of time. Even though they are both black gemstones, onyx, a mineral, has a sharp luster, while jet is characterized by its moist texture and deep luster, due to these differences in origin. Jet, which was called [black amber], was thought to be [hardened resin] like amber until the early 20th century when [tree rings] were confirmed by microscopy. This jet is the most basic round bead type, and the NE set allows you to enjoy the elegant jet black. Please use these rather large 10.0mm beads to create a solemn and elegant effect!
