Colorless diamonds are gemstones that exhibit little to no color, making them highly sought after in the jewelry market. Their clarity and brilliance are often measured using the GIA grading scale, which assesses factors like cut, clarity, and carat weight. The absence of color allows these diamonds to reflect light beautifully, enhancing their sparkle. These diamonds are formed deep within the Earth under high pressure and temperature conditions. The most common source of colorless diamonds is the mineral carbon, which crystallizes over millions of years. Their rarity and aesthetic appeal contribute to their value, making them a popular choice for engagement rings and other fine jewelry.
