Aquamarine is a type of beryl mineral. The gemstone got its characteristic name for its color. From the latin «aqua marina» – «sea water», which is a true description of the color of the mineral. A characteristic of natural aquamarine is its color: bluish green, greenish blue, sky blue, sky blue to dark blue (very rare). Usually it has a very light color, which is clearly visible only in large specimens. Rare blue-colored gem beryls are known as «maxixe». They were first found in 1917 in Brazil at the Maxixe mine. Their color is unstable and tends to fade quickly in the light. Saturated color instances are also referred to by the trade term “Santa Maria.” According to their properties, these stones are similar to maxixe, but usually their color is slightly lighter. If the color is almost green, with only a faint blue tint, then such an instance would be more correct to consider simply beryl. We tell you more about coloring in the Buyer’s Guide.
