The deeply saturated blue variety however is the most valuable – this hue occurs when the stone is heated to 750 degrees, and when observed under a microscope it will often also display subtle shades of green.

The inner structure of aquamarine is also fascinating – it forms into beautiful transparent crystals which are usually flawless, contrary to the beryl variety emerald which contains many inherent inclusions (natural tiny cracks).
