The birthstone for the month of April is the diamond. Diamonds are renowned for their brilliance, hardness, and rarity, making them highly valued in jewelry. In addition to their aesthetic qualities, diamonds symbolize strength, resilience, and eternal love, which is why they are often used in engagement rings. The term "diamond" comes from the Greek word "adamas," meaning invincible or unbreakable. Their formation occurs deep within the Earth over millions of years under high pressure and temperature conditions, leading to the creation of this precious gemstone, which is often characterized by its exceptional clarity and light reflection.
