Canary diamonds are a type of colored diamond known for their vibrant yellow hue. This color comes from the presence of nitrogen atoms in the diamond's crystal structure, which absorb blue light and reflect yellow light. The intensity of the yellow can vary, leading to classifications such as light yellow, fancy yellow, and fancy intense yellow. These diamonds are highly sought after in the jewelry market due to their unique color and rarity. Canary diamonds are often used in engagement rings and other fine jewelry pieces, making them a popular choice for those looking for something distinctive and eye-catching.
