The Aquamarine, from blue green to deep sea blue.

 

Emerald is by no means the most expensive gem to be found among the varieties of beryl, while other types of beryl could also be very valuable. Even if beryl is rather a common rock forming silicate there are quite a number of beryls which are cut as gemstones.

 

aquamarine ring by jeweller Hilde Van BelleghemOne of the most beautiful beryl is the aquamarine. Its name describes it quite accurately as “sea water” gem. Have you ever stood near the bow of a moving vessel and watching the lovely green plume slide away from almost under your feet? That is exactly the colour of aquamarine. Sometimes there is more blue than green in the tint of the gem, as in the instance of some Brazilian stones, which are superbly blue.

Julia intaglio with aquamarineAquamarine was already popular during the Roman period and was mostly engraved with portraits (called intaglio), as the famous aquamarine of Julia, daughter of Emperor Titus (see the picture).

In some aspects Aquamarine equalizes almost the most valuable coloured gemstones, as ruby, sapphire, emerald and tanzanite. The most beautiful aquamarines originates from Brazil, while Mozambique has also very nice specimens. Most of the aquamarines are heated, which is an accepted practice by the industry. It is almost impossible to make the difference between a heated and non heated aquamarine. A synthetic aquamarine doesn’t exist. Gemstones as aquamarine chrysolite and aquamarine topaz are from another origin than aquamarine. They are only indicating the exceptional colour of the gemstone.
