When evaluating the quality of aquamarine, there are several key factors to consider. Use our easy guide to determine the best gemstone for you.
COLOR: Aquamarine is most valuable when it is a deep, even blue without any green. This is known as “Santa Maria” color. Pale stones with grayish tones are less desirable.
CLARITY: Aquamarines should not have visible inclusions. Those that do are usually fashioned into cabochons, beads, or carvings.
CUT STYLE: While most are cut into standard shapes and sizes, high-quality gems are custom cut. Watch out for windowing (large areas where light leaks out the pavilion without being reflected back through the crown).
CARAT WEIGHT: Aquamarines come in all sizes, from small to enormous. It’s difficult for enormous gems to be used in jewelry, so per-carat price can decrease for gems above 25 carats.
LOOK-ALIKE: Some blue topazes look like aquamarine, but aquamarine is much more valuable. Be sure to purchase an aquamarine with a GIA report to be certain of your gem’s identity.
