| Diamond is an allotrope of carbon. It is the hardest known natural material and the third-hardest known material after aggregated diamond nanorods and ultrahard fullerite. Its hardness and high dispersion of light make it useful for industrial applications and jewelry. Diamonds are specifically renowned as a material with superlative physical qualities — they make excellent abrasives because they can be scratched only by other diamonds, Borazon, ultrahard fullerite, or aggregated diamond nanorods, which also means they hold a polish extremely well and retain their lustre. Diamond is the hardest natural material known to man - its hardness set to 10 (hardest) on Mohs scale of mineral hardness[6] and having an absolute hardness value of between 90, 167, and 231 gigapascals in various tests. Diamond's hardness has been known since antiquity, and is the source of its name. However, aggregated diamond nanorods, an allotrope of carbon first synthesized in 2005, are even harder than diamond. The hardness of diamonds contributes to its suitability as a gemstone. Because it can only be scratched by other diamonds, it maintains its polish extremely well, keeping its luster over long periods of time. Unlike many other gems, it is well-suited to daily wear because of its resistance to scratching—perhaps contributing to its popularity as the preferred gem in an engagement ring or wedding ring, which are often worn every day. Industrial use of diamonds has historically been associated with their hardness; this property makes diamond the ideal material for cutting and grinding tools. The diamond is the birthstone for people born in the month of April, and is also used as the symbol of a sixty-year anniversary, such as a Diamond Jubilee | antique jewelry antique jewelry bead jewelry pattern bead jewelry pattern bead jewelry bead jewelry beaded jewelry beaded jewelry body jewelry body jewelry Brighton jewelry Brighton jewelry chanel jewelry chanel jewelry costume jewelry costume jewelry crystal jewelry crystal jewelry custom jewelry custom jewelry designer jewelry designer jewelry estate jewelry estate jewelry friedmans jewelry friedmans jewelry gordons jewelry gordons jewelry handcrafted jewelry handcrafted jewelry hip hop jewelry hip hop jewelry Indian jewelry Indian jewelry jared jewelry jared jewelry jareds jewelry jareds jewelry jewelry appraisal jewelry appraisal jewelry appraiser jewelry appraiser jewelry armoire jewelry armoire jewelry auction jewelry auction jewelry buyer jewelry buyer jewelry design jewelry design jewelry display jewelry display jewelry exchange jewelry exchange jewelry making supply jewelry making supply jewelry making jewelry making jewelry repair service jewelry repair service jewelry repair jewelry repair jewelry school jewelry school jewelry supply jewelry supply jewelry television jewelry television jewelry TV jewelry TV jewelry watch jewelry watch jewelry watches jewelry watches juicy couture jewelry juicy couture jewelry Kay jewelry Kay jewelry Kays jewelry Kays jewelry lia Sophia jewelry lia Sophia jewelry magnetic jewelry magnetic jewelry Pandora jewelry Pandora jewelry silpada jewelry silpada jewelry tiffany jewelry tiffany jewelry tiffanys jewelry tiffanys jewelry titanium jewelry titanium jewelry wedding cake jewelry wedding cake jewelry Whitehall jewelry Whitehall jewelry wholesale body jewelry wholesale body jewelry wholesale costume jewelry wholesale costume jewelry wholesale fashion jewelry wholesale fashion jewelry wholesale jewelry wholesale jewelry wholesale silver jewelry wholesale silver jewelry wire jewelry wire jewelry Zales jewelry Zales jewelry big diamond ring big diamond ring cazo jewelry cazo jewelry diamond bridal ring set diamond bridal ring set e jewelry world e jewelry world famous jewelry store famous jewelry store friedmans jewelry friedmans jewelry Gordons jewelry Gordons jewelry jared jewelers jared jewelers Jareds jewelry Jareds jewelry jewelry case jewelry case jewelry findings jewelry findings jewelry images jewelry images jewelry set jewelry set jewelry web stop jewelry web stop Jim jewelry Jim jewelry juicy couture jewelry juicy couture jewelry lia Sophia jewelry lia Sophia jewelry premier design jewelry premier design jewelry the jewelry exchange the jewelry exchange tiffany diamond ring tiffany diamond ring unusual jewelry unusual jewelry Whitehall jewelry Whitehall jewelry Zasha Zasha Zasha jewelry Zasha jewelry fun day time fun for fun hour a fun time fun week is lots of good fun more.
