The color of Australian blue sapphire is often described in what way?

Australian blue sapphires are often described as "inky" due to their deep, rich color saturation and the presence of a varied hue that can have a hint of violet or indigo. This term captures the essence of their appearance, which can resemble the dark, almost opaque qualities associated with ink, offering a strikingly dark blue that is both alluring and complex. This description reflects the unique character of these gemstones and is distinguished from lighter shades, which would not accurately capture the typical visual attributes of Australian blue sapphires.
