Diamonds are created in the Earth's [[mantle]], due to forces and heat required for their creation, and are sometimes brought near the surface through volcanic eruption.<br /> <br /> Diamonds are also noted for being the hardest metal known to man, and fairly rare (deposits are found in [[Kimberlite]] in [[South Africa]]). As such, natural diamonds are used for jewelry, and synthetic diamonds for drill bits.<br /> <br /> Diamond is the traditional stone for engagement rings, and is the [[birthstone]] for [[April]]. <br /> <br /> ==External Links==<br /> [http://www.minelinks.com/alluvial/diamonds.html Minelinks.com - Diamonds]<br /> <br /> [http://www.about-birthstones.com/aprilbirthstone.html About-birthstones.com - April birthstone] <br /> <br /> [[category:Birthstones]]<br /> [[Category:Gems]]</div>
