Diamons are a precious gemstone that is highly valued for its beauty and rarity. They are the hardest natural substance known to man, and have been used in jewelry and other decorative items for centuries. The term 'diamonds, say' can refer to the fact that diamonds are often referred to as 'ICE' or 'sparkles' due to their reflective properties. Additionally, diamonds are often used as an ASSET, which is a five letter word.
