Ceylon Aquamarine is a gemstone that has been mined in Sri Lanka since the early 1900s. The name "Ceylon" was used at the time to describe the island nation, which is now called Sri Lanka. It's a type of beryl, and it's most commonly found in shades of blue and green.
The gemstone gets its name from its resemblance to the color of water. Its most vivid color is a deep blue-green hue that looks very similar to an ocean or lake on a sunny day. It can also be found in shades of light green, yellowish green, brownish green and even reddish hues. Because it comes in so many different hues, Ceylon aquamarine can be used as an accent stone or center stone for jewelry pieces such as rings or pendants.
