How to Tell if an Aquamarine is Real

March 7, 2018

If you are interested in purchasing the March Birthstone Aquamarine, there are a few things to know before you buy. The color and clarity of the stone will determine it's value and because they are found in nature in fairly large sizes the carat weight does not go up exponentially with larger stones.  Aquamarines range in color from light to deep blue. They are generally heated to remove any yellow coloring. The deeper colors are generally more valuable so long as the clarity is good. Also, unusual cuts of Aquamarine such as Asscher  are generally worth more.


How can you tell if you are dealing with a real Aquamarine instead of Blue Topaz or even glass? Ask the jeweler to borrow a loupe which is a little eye piece for examining stones up close.  Check the surface of the stone for scratches.  Aquamarine is a very hard stone and should have no scratches. If you see scratches or bubbles within the stone, it is most likely glass.  Look at the stone from different angles. Aquamarine is pleochroic so it will show different colors from different angles. If the color stays the same as you angle it, it is not an aquamarine.  You can also touch the stone to your forehead. If it feels room temperature, it is probably glass. Aquamarines stay cool to the touch.  


Aquamarines are beautiful no matter what month you were born in ! Enjoy your beautiful Aquamarines!
