The deeper the color of an aquamarine, the more valuable it is. Before the era of magic spirits, gemstone appraisal institutions designated a unique color name for aquamarines with top-tier colors, calling it "Saint Maria" color.
Just like the Jedi Knight for spinel, aquamarine must meet specific color standards to be called Saint Maria Aquamarine.
The Saint Maria color aquamarine and London Blue Topaz have somewhat similar colors, but the color of London Blue Topaz is artificially processed, so the color standards are uniform without any color difference.
Saint Maria Aquamarine, however, is different. Even if they are all Saint Maria colors, the tones can vary from deep to light; as long as they meet certain standards, they can be called Saint Maria color.
This particular Saint Maria Sea Blue Sapphire is noticeably deeper in color than most Saint Maria tone aquamarines and more closely resembles London Blue Topaz.
