Aquamarine Gemstone Information
About Aquamarine - History and Introduction
Aquamarine is a blue to green-blue gem-quality variety of beryl. The beryl group of gemstones is most famous for chromium-rich green emerald, one of the 'precious four' gems (diamond, sapphire and ruby are the remaining three). Aquamarine is an official birthstone for those born in March. Aquamarine is exceptionally hard and has an outstanding vitreous glass-like luster. It is most famous for its breathtaking sea-blue colors which can range from pale light blue to medium-dark blue. The name 'aquamarine' was derived from an old Latin expression which meant 'seawater'.
Aquamarine and emerald belong to the same family, but they are surprisingly different. Aquamarine and emerald are both beryllium aluminum silicates, but emerald is colored by trace amounts of chromium (and sometimes vanadium), while aquamarine obtains its color from iron impurities within colorless beryl (goshenite). Aquamarine and emerald have essentially the same specific gravity and refractive index, but emerald tends to be hazy and full of inclusions, while aquamarine is known to occur with excellent transparency and clarity.

Aquamarine derives its name from the Latin term for seawater and has a long tradition of being a stone for those who spend much of their time at sea. The Greeks and the Romans knew aquamarine as the sailor's gem too, believing that it ensured a safe and prosperous passage across stormy seas. Legend has it that aquamarines were the prized possessions of many mermaids and would thus protect sailors from the dangers of sea, including warding off sea-sickness.

It is no surprise that aquamarine is assigned to the planet Neptune and is also one of March's official birthstones.
