The precious stone commonly associated with love is the diamond. Diamonds are often regarded as symbols of romance and commitment, making them a popular choice for engagement rings. Their exceptional clarity and brilliance have captivated admirers for centuries, and they are frequently used in jewelry to signify enduring love. The tradition of giving diamonds as a token of love is rooted in cultural practices and marketing campaigns, particularly those dating back to the 20th century. Diamonds are also celebrated for their rarity, and the phrase "a diamond is forever" underscores the belief that love, like a diamond, should last an eternity.
