Beryl (Emerald, Aquamarine & Morganite)
Aquamarine’s cool blue hues are reflected in its name, which comes from the Latin for “sea water”. The gem has usually an excellent clarity and its color range goes from greenish blue to blue-green in light tones. The stone can be heated to remove a yellowish tint, resulting in purer blue color. The major source is Brazil and aquamarine is the birthstone for March.
Emerald is the most famous member of the beryl family. Its color reflects new spring growth, which makes it the perfect birthstone for May. It’s also the gemstone for the twentieth and thirty-fifth wedding anniversaries. Emeralds are found in Colombia (fine Colombian emeralds are highly regarded for their excellent color), Zambia (Zambian emeralds tend to have good clarity) and Zimbabwe, among others. Emeralds typically contain inclusions that are visible to the unaided eye and are often described as looking mossy or garden-like. Eye-clean emeralds are especially valuable because they’re so rare.
Morganite’s finest color is a deep magenta but most morganites on the market are a pale pink. The gem’s beauty and limited availability make it a favorite of collectors. The major sources are Afghanistan, Brazil, Madagascar and US.
