The Aquamarine is the Birthstone for March, as well as a wedding gift for those celebrating their 19th wedding anniversary.

Since ancient times, its history has been linked to the sea and to sailors.

Aquamarines have been used by seamen as amulets for centuries. Sailors believed that aquamarines had magical and/or healing powers if they were carried as talismans, protecting them from the wrath of the Sea God, Poseidon, as though these gems were a gift from the seabed brought up by the sirens themselves. 

Centuries ago, Aquamarines were used as an antidote to poison, as an oracle, amulet, healing stone, etc.

"To those who are able to explore their secrets, precious stones relate to story as interesting as that of the huge pyramids erected by the Pharaohs at Memphis, and it would seem that their sublime internal spheres might be called, The Fingerprints of God" and also he called them "The usurpers from the factory". 
Edward J. Gübelin Inclusions as a Means of Gemstone Identification, 1953.
I think the best way I have to show my customers that my stones are natural is by showing them their interior, which is unique and beautiful. The scale of microphotography can be up to X50.

AQUAMARINE GEMSTONE: 

Aquamarine belongs to the beryl family, just as the Emerald, Morganite, Goshenite, Red Beryl, Green Beryl, Heliodor and Maxixe; and it owes its color to iron trace elements.

The origin of the name from  the latin words “aqua” (water) and “marina” (sea), in reference to seawater color. Aquamarine evokes the tranquility and security, like a calm sea.

COLOR
Aquamarine is the blue to greenish blue variety of the beryl group.
This blue color have different hues:

Aquamarine can be light or dark blue, greenish blue to pale green - blue.  The commonest color is a pale to medium blue or greenish blue. The most expensive aquamarine have a saturated blue color without inclusions, vitreous lustre and transparency.

CUT & SIZES
Aquamarine cut stones are available in a wide variety of shapes. Apart of convencional cut (emerald, oval, pear, round, trillion, pear, etc) we can find fancy cuts. Emerald cut aquamarine is highly sought in jewelry.
Cabochon cutting is probably the most common form of gem cutting for translucent aquamarine, and faceting cutting for transparent aquamarine.

Aquamarine is available in large sizes, smaller aquamarine gems (under 5.00 ct.) often show lighter color.

CLARITY & INCLUSIONS

Aquamarine  are usually eye-clean, (the inclusions cannot be seen with the naked eye) with great lustre and transparency.
Typical inclusions: The main inclusions are parallel “tubes” or “channels” to axis C,  solid inclusions (ilmenite, goethite, apatite, quartz, etc.), multi-phase inclusions, sometimes resembling iridescent “confeti”, healed fractures, feather or fingerprinters.

The characteristics and arrangement of the inclusions are responsible for the ASTERISM and CHATOYANCY in the aquamarine gemstone.
