Aquamarine is Latin for ‘water of the sea’ and what a perfect description of the colour of the stone.
Naturally, the stone should be a seawater colour, with dark blue being the most admired. Less fine quality stones are often heated to turn them to a stronger blue and fashion has influenced this by making the stronger blue more desirable than the natural blue/green of the stone.
The stone is quite hard, (moh’s scale 71/2 -8) however it is brittle and can be known to chip. If worn in a ring it is best for special occasions or delicate wear…not gardening and washing up!
As part of the beryl family, Aquamarine has the same chemical construction (aluminium beryllium silicate) as Emeralds, Morganite (soft pink), golden beryl and Heliodor….so how come they all are different colours I hear you ask? Well, Emerald’s colouring agent is chrome, Aquamarine’s colouring agent is iron….(there can be green beryl’s that are not green because of chrome but because of vanadium and therefore they can never be called an Emerald). It’s all back to the mix of ingredients when these rocks are formed.
All this may be a bit confusing…but in the silicate slush in the centre of the earth these are the chemicals that naturally may or may not be present….it is like the earth’s natural larder…and what is available that day will dictate the colour and type of stone that is the result.
If you are born in march you are lucky enough to claim Aquamarine as your birth stone…however as there are no rules. If this is your favourite colour you can still treat yourself to one of these beauties!! Just remember – even though white diamonds complement the Aqua very well…you can be more adventurous as you can see with the gorgeous orange of these hessonite garnets…
