What is Aquamarine?
The name aquamarine is derived from the Latin words “aqua” meaning water and “marina” meaning the sea. The different hues of the sea can be seen in each variant of the aquamarine stone. It’s not difficult to see why many call it “the sea in a stone”.
Aquamarine is a semi-precious stone that rates 7.5 to 8 on the Mohs scale. This scale ranks gems based on their hardness and scratch resistance. This makes aquamarine durable enough to be worn on jewelry (we’d steer clear of all manual labor while wearing this gem).
What does the Aquamarine stone look like?
As with diamonds, gemstones derive their value from the 4 C’s: carat, color, clarity, and cut. This is the global standard for evaluating and grading the value of a gemstone. Although picking out the perfect gem is a choice made from the heart, keep these factors in mind to ensure you get the best value from your choice.
Carat
The size of the gemstone is measured by weight in carats. You guessed it, the more blinging your crystal, the more you will need to fork out for it. The more intense colored gems are usually over 5 carats.
Color
The colors of aquamarines range from pale blue to turquoise or deep blue, all impacting the value of the gem. The color of a gem is determined by 4 components:
- Hue: the name of the color, in this case, blue
- Saturation: the brightness of the gem’s color which could be dull, strong, or vivid
- Tone: the depth of the color ranging from light to medium or dark
- Coverage: the consistency of the color throughout the gemstone
These 4 factors create the overall color of the aquamarine and determine its value. The deeper blue hues are considered to be the most valuable type of aquamarine. Luckily though, the more popular turquoise aquamarine is more reasonably priced.
The color of the aquamarine is dependent on the size of the stone. Larger stones often have a more intense hue while the smaller gems are more pastel in color. Some aquamarines are heat-treated to bring out their striking blue color. Not to worry though as this won’t affect the stone’s structure and you won’t need to take special care of these gems.
Clarity
The degree of transparency of the gem determines its clarity. The fewer inclusions the better the gem is classed. This increases the value of the stone. Usually, aquamarines are free of inclusions visible to the naked eye.
Cut
A properly cut stone will allow the other 3 C’s to shine brightly. Common cuts for aquamarine are the emerald cut followed by the oval and pear-shaped cuts. Aquamarine is a versatile stone, many jewelry designers can create different cuts and shapes letting their imagination run wild.
