flawless diamond 468x327 Diamond is no longer nature’s hardest material

Diamond will always be a woman’s best friend but the gemstone is no longer the world’s hardest material, according to scientists.

Instead, a rare natural substance, called lonsdaleite, which is made from carbon atoms just like diamond, has emerged as 58 per cent harder than the gemstone, according to a report in the New Scientist.

Rare mineral lonsdaleite is sometimes formed when meteorites containing graphite hit Earth. Via ItvNews
