Pink Diamond is a rare and valuable gemstone known for its stunning pink hue. These diamonds are formed deep within the Earth under extreme pressure and temperature conditions. Their unique color comes from a specific arrangement of carbon atoms, which can create various shades of pink, from light to deep rose. Due to their scarcity, Pink Diamonds are highly sought after by collectors and investors. They are often graded based on color, clarity, cut, and carat weight. The most famous pink diamond is the Hope Diamond, which has a rich history and is currently housed in the Smithsonian Institution.
