What does diamond color J-K mean?

Diamonds with a color grade of J-K are considered near-colorless, meaning they exhibit a slight tint of yellow or brown that is typically not easily noticeable to the untrained eye. In the GIA grading scale, J is the lower end of the near-colorless range, while K indicates a more noticeable tint. These diamonds can offer a good value for buyers seeking larger stones without a significant premium for higher color grades. However, it's essential to consider how the color affects the overall appearance, especially in different lighting conditions.
