Aquamarine is a form of the mineral beryl which makes it a part of the same mineral family as the massively popular and long time loved emerald.

Beryl itself can come in a wide variety of different colours and there are many common gemstones that belong to the beryl mineral family including morganite, a pink variety of beryl and heliodor, a golden variety of beryl.

The rarest and most expensive form of beryl is red beryl.

Who knew aquamarine has so many brothers and sisters eh?….

2. Aquamarine Has A Hardness Of 7.5-8 On The Mohs Scale

OK, so here is where it might get a touch confusing if you’re unfamiliar with the Mohs scale…

Aquamarine, like other gemstones from the beryl mineral family, has a reputation for being a more brittle gemstone. So why the high rating you might ask?

Well the Mohs scale doesn’t actually record the ‘hardness’ of a gemstone, if you will. The Mohs scale actually rates scratch resistance. This means its ability to resist scratching from a harder, or higher rated mineral.

So this is why aquamarine, as well as other beryl minerals have such a high rating while being known for being brittle.

3. It’s Name Comes From The Latin Word For ‘Aqua Marina’

The name aquamarine is actually derived from the Latin word aqua marina, which translates to sea water in English. This of course, was due to the colours of the aquamarine gemstone being reminiscent of the colours of the sea.

4. Aquamarine Is Steeped In Myth & Legend

As mentioned above, the connection between aquamarine and the ocean is much more than just its name and colours.

Many years ago, sailors actually used to take aquamarine with them on board their ship when out at sea. This was for a number of reasons.

Firstly, it was widely believed that aquamarine would keep them safe while they were on their journey at sea. It was believed to offer protection against both seasickness & shipwreck to help them get home safely. Some people were also of the belief that it would in fact protect them from Satan.

It’s said that another reason aquamarine was taken aboard ships by sailors was that they believed the stone was treasure from mermaids.

It wasn’t just sailors who believed that aquamarine brought protection to its owner though. Aquamarine has long been seen as a stone that brings safety and in the early days it was even worn into battle…

5. The Stone Of Courage
