An revered, late author Sir Scott Cunningham speaks of this, talismanic use of this stone:
Same author also suggests it as a purification stone, and a well suited gift for conjugal happiness, if the mates are to exchange these.
It was also believed to give courage, and fights the spirits of darkness, while attracting the spirits of light 
It’s considered to be a lucky charm of those individuals that are born in March or October. It’s considered widely to be a birthstone o f the Pisces.
In crystal therapy
Various sources suggest Aquamarine , as a very versatile and powerful healing stone**
In crystal healing It’s used to treat inflammations, swollen glands, thyroid associated conditions , sometimes also conditions related to thymus, it’s used to treat the respiratory tract inflammations, pneumonia, it acts as tonic for detoxification organs . It is also widely used, and reputed to be extremely efficient in treating infections of jaw, teeth, and eyes, as well as improving the eyesight and general mouth cavity health.
Mentally it calms the mind, wipes out effects of stress, brings tranquility, aids meditation, and helps us finishing the things we started, get back on track, removes confusion and sharpens the intellect.
It can be placed on the thorat chakra, or where needed. Crystal essence is great mind tonic, and is also said to strengthens psychic abilities. Pair can be placed on eyes, and it’s placed under pillow to help prevent nightmares and bring about tranquil, restful sleep.
Now, here are some ideas on “practical” applications of the ston e in spell casting and rituals, this is a practical type of blog, ya’ know :P
Overpower evil Aquamarine charm
Aquamarine is said to confer to power to conjure the De**l himself, and to force him to speak trutfully and resist his deception and fascination, If only the stone was to be hid in the mouths and remain there. 
I can see how that could/would work, more so If the stone would be inscribed with a let’s say image of Scorpio, SDPNQCN charm, SATOR square, David’s star with Tetragramaton inscribed.
Inscribe a flat or thumbed Aquamarine with an Hexagram ( David’s Star , Hebrew Star ) , that holds Tetrgramaton in it’s Centre.
“Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you.” 
If You have , You may add few drops of “Victory over evil” oil on the stone, upon finishing with the praying or even before. Otherwise, placing it in small amount of Holy water overnight, somewhere where the light of the Full Moon may reach it, is equally good alternative.
Consecrated in this manner, Aquamarine will make a charm against evil spirits “par excellence” , and if such stone would be placed in the mouths while dealing with demons, it would indeed be a fine protection from their deception or misbehavior. Hence would make an amazing charm for practitioners of Higher magick. If You can not carve the stone , You could alternatively draw the symbol on a small parchment paper, tie it to, or wrap around the stone.
As we have seen Aquamarine is widely reputed to be a stone that strengthens psychic powers.
· Cherry Opal stone
And carry with You, place under pillow and on forehead to strengthen the ESP abilities, such as; precognition, intuition, psychometry, clairvoyance and other.
To dream of the Future, or anything You want to know, to have prophetic dreams, try and make a smaller amount of “Lunar slime” with Aquamarine placed in water , making thus also an Aquamarine essence. Then, the next day make the same amount of Mugwort infusion. Combine the two together, and drink , prior to the sleep , and place the Aquamarine under Your pillow. You make say the question aloud, or in Your head, during prior to falling asleep.
Aquamarine honesty spell
This spell is intended to give someone courage, and inspire them to be open and trutful to You. When I wrote it I was not aiming for coercive , compelling truth spell effect , like commonly sought by people . With that being said this spell will help someone be honest to You, but will not cause someone to tell You the truth even If they would never normally do so, this spell will inspire people to confide to You or be honest, as much as possible in their situation .
Like most of “crystal-centered” spells it’s fairly simple;
· Say the following words :
“Open thy mind, open thy heart
Courageously and honestly,
Speak clearly and truthfully! “
· Repeat for Seven days, unless You think once will do ( let’s say person in question is just mildly dubious about whether they should confide to You or not, for example )
Many Blessings, Shadow :)
