Gem producing countries with iron rich earth make ideal conditions for the formation of blue green sapphire colour. Iron is also a quencher of light which means when light falls on the gemstone, it absorbs much of the light instead of reflecting it - making blue green and teal sapphires much darker. Blue green and teal sapphires from Madagascar for example, typically have less iron content than Australian sapphires and therefore tend to be more reflective and brighter. The beauty of a teal sapphire relates to how differently it can look under certain types of light! This is because different types of light have different proportions of wavelengths.

The time of day can also affect how your sapphire can look, depending on the lighting conditions.
