Jewelry is a form of personal adornment, such as brooches, rings, necklaces, earrings, and bracelets. With some exceptions, such as medical alert bracelets or military dog tags, jewelry normally has no other purpose than to look appealing, but humans have been producing it for a long time - with 100,000-year-old beads made from Nassarius shells is the oldest known jewelry.
Jewelry may be made from a wide range of materials, but gemstones, precious metals, beads and shells have been widely used. Depending on the culture and times jewelry may be appreciated as a status symbol, for its material properties, its patterns, or for meaningful symbols. Jewelry has been made to adorn nearly every body part, from hairpins to toe rings.The word jewelry itself is derived from the word jewel, which was anglicized from the Old French 'jouel', and beyond that, to the Latin word 'jocale', meaning plaything. In British English the spelling can be written as jewelery or jewellery.
In mineralogy, diamond is an allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at ambient conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.
