[Your and My Jewelry Box] Jet Black Necklace and Earring Set, 8.0mm Black

Natural Jet: Approximately 8.0mm Length: Approximately 42cm Clasp: Brass insert type Fittings: Titanium post and catch Total weight: Approximately 21.0g Jet is a gemstone originating from organic matter, formed 180 million years ago during the Jurassic period when dinosaurs ruled the Earth. Ancient plants became driftwood, accumulated on the seabed, and fossilized over a long period of time. While onyx, a mineral, is also a black gemstone, it has a sharp luster, whereas 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 using a microscope. This jet is the most basic round bead type, and the NE set allows you to enjoy the elegant jet black. Make a solemn impression with the slightly larger 8.0mm bead!
