Medium to Light Blue: Aquamarines with medium to light blue colors are still highly desirable. These stones may display a delicate, calming blue reminiscent of the ocean.
Greenish-Blue: Some aquamarines may exhibit a greenish-blue or teal-like color. While still attractive, they are generally considered a separate category and may be priced differently.
