7. Buying an Aquamarine Engagement Ring


Proposing with an aquamarine engagement ring can be a perfect choice for couples seeking a birthstone engagement ring or among couples who adore the calm, soothing and minimalistic appearance of the breath-taking aquamarine.


Choosing a good colored aquamarine wisely will complement the custom setting and make the ring stand out and shine in brilliance.




Colored by the element Iron, finest quality aquamarines emit a medium dark blue to greenish blue color. Unlike other gemstones, the value of aquamarine comes mainly from its tone rather than hue and saturation.


At Nolan and Vada, we handpick medium to dark toned aquamarines, ethically produced from the mines in the region of Brazil and Africa





To retain maximum clarity and brilliance, aquamarines are cut to bring out the best shades of blue to blue-green from the rough.


The crystal nature of the gemstone makes emerald cut the most popular shape however, other shapes such as oval, round and cushion are seen quite regularly as well.




Generally, aquamarines are less included than other gemstones and most of the aquamarines are usually eye clean and lack visible inclusions seen by naked eye.


Fine aquamarines are known for their excellent transparency hence you should not compromise on clarity. At Nolan and Vada, we hand pick aquamarines high in clarity where inclusions are not visible to naked eye (eye-clean)





Being a slightly denser gemstone than diamonds, an aquamarine similar to a size of diamond can weigh more. For example, an approximate 1.20 carat aquamarine will visually look similar in size to a 1.00 carat diamond.


Popular size in carat weights for engagement rings among aquamarine fall under 2.00 carats ~ 4.00 carats

8. Enhancements

When mined, most aquamarines come with a slight greenish tint which is routinely removed by acceptable trade practice of heating to approx. 375°C. Heating aquamarine is a very common practice as it does not affect the tone, only the hue of the stone.


Since the process of heating is impossible to detect and distinguish among aquamarines, it is safe to assume that most pure blue aquamarines are probably heated.

9. Certification
