Aquamarine is a greenish-blue to pale blue member of the beryl family (which also includes emerald) and is known for its delicate blue or blue-green colouring, which accounts for its name.
Aquamarine is a popular stone with very good hardness (7.5 to 8 on the Mohs scale) and impressive lustre. The stone’s hardness protects it to a certain extent from scratching and makes it an excellent choice for all kinds of jewellery that is worn on a regular basis. The most popular cuts are emerald (step) and brilliant cut with long or rectangular shapes.
Much more often than its famous green cousin, aquamarine is almost entirely free of inclusions.
According to legend, aquamarine was originally found in a treasure chest owned by mermaids and therefore it has long been regarded as a lucky stone for sailors.
Aquamarine is the birthstone for those born in March.
