Diamond

Diamond is without a doubt the most popular gemstone in the world with more efforts invested in its mining and cutting than any other. Diamond is one existing structural form of carbon and is the hardest mineral on earth. Admired for not only its strength but also its beauty, the name diamond is derived from the Greek ‘adamas’ meaning unbreakable. The Pink Star diamond currently holds the record for highest sale price at auction at £59m. When buying diamonds over a certain weight, customers can consider the four Cs in diamond grading - colour, cut, clarity and carat.
