Aquamarine is a very durable gemstone; it has a rating of 7.5 to 8.0 on the Mohs’ Scale of Hardness. Aquamarine looks stunning in several cuts or shapes including round, heart, and princess. It also has a modest refractive index, which contributes to the moderate brilliance and sparkle of the well-cut gem.
The natural color of aquamarine is usually light green with yellowish tints, although the gem with a light blue is rarely found or mined from nature. In fact, most aquamarines in the jewelry market are heat-treated. For instance, other gems such as beryl are treated to get rid of their colors and thereby enhance blue tones making them appear similar to aquamarine.
The meaning of the gemstone is deeply linked with water. People used to believe that the gem is a talisman that provides protection against unforeseen events and aids in relationships through its calming and healing influences.
If you are planning to choose an aquamarine engagement ring, go for a light blue color. The color associated with the azure ocean is perfect for aquamarine center stone. This is the birthstone of March month and is believed to be a lucky gem for people with Pisces zodiac sign. In fact, aquamarine rings with diamonds are very popular in the gems and jewelry segment, so you can consider that as a birthday or anniversary gift too.
