This ocean blue stone is a favorite among many including the lucky ones who have it as their birthstone. Aquamarine is a member of the Beryl family also related to Morganite (another favorite of ours!). This stone is a great option for an alternative engagement ring as the stone has a hardness of 7.5 to 8 on the Mohs Scale. Our favorite source, the GIA has this to say about Aquamarine:
Aquamarine’s name comes from the Latin for seawater and it was said to calm waves and keep sailors safe at sea. March’s birthstone was also thought to enhance the happiness of marriages. The best gems combine high clarity with limpid transparency and blue to slightly greenish blue hues. Like many beryls, aquamarine forms large crystals suitable for sizable fashioned gems and carvings.
