The Aquamarine is the birthstone for March. An Aquamarine of the best quality is clear, transparent and eye-clean, which means it does not have inclusions visible to the naked eye. Some stones may carry liquid inclusions, while some have long, hollow, rod-like inclusions that are common in gems of the beryl family. The best way to identify a real Aquamarine stone is by looking at its colour. In its natural form, they have a pale blue colour, which is similar to seawater. They may have a slight green or yellow tint as well. Naturally occurring gems have excellent clarity and transparency.
