Prasiolite is the the member of the Quartz family. It's name derives from the Greek word meaning ''Leek'' and the Prasiolite's color is leek green.
It starts out as a type of purple Amethyst and it's color is changed to green by heat, hence the nick name, Green Amethyst.

Prasiolite allows for the grounding of high- frequency energy through the heart.
It's energy triggers the heart center to open to the energy of the earth and one's Higher self. This allows one to become a ''lightening rod'' of healing energy for the earth.
Prasiolite brings a syntheses between the higher and lower aspects of the body.
Linking with the vibration of purple amethyst, green amethyst helps one act on higher guidance, following one's heart upon the path of Spirit. With it's connection with Citrine, Green amethyst enables one to link the personal will to Divine Will, so one may be conduit for the expression of Divine will on earth.
It also opens the Crown and Third-eye Chakras, initiating inner vision. It supports healing work done on a shamanic levels through Earth- directed spirituality.
It can help one connect and connect and communicate with terrestrial inter dimensional beings.

Physical:

Prasiolite is an excellent stone for supporting the physical heart.
It also useful in issues of digestive, stomach-acid imbalance, assimilation of nutrients and cellular nourishment. It can aid in remedying eating disorders.

Working well with others:

Wearing, holding, or carrying Prasiolite with Purple Amethyst amplifies one's connection to the higher spiritual realms.
Prasiolite also harmonizes well with Danburite, creating a link with the angelic domain and facilitating Light Body activation.
Combining it with Moldavite increase power and speed of the affects of prasiolite.

Who they are and what they teach

Prasiolite, green-quartz or vermarine is a green-colored form of quartz, usually produced by artificially heat-treating amethyst. Sometimes is confused with green beryl, peridot (olivine) & tourmaline. This material is occasionally referred to as "green amethyst" which is considered a hybrid stone by gemologists.

Heating

Heating is the most common treatment which can alter the color of a stone to lighten, darken, or change completely. Very dark amethyst is heated to produce lighter shades. Most of the amethyst available in the gem market is enhanced to get exotic shades. On treating Amethyst under controlled conditions one can produce some very astonishing colors or intensify the royal purple color at 400c to 600c. This heat treatment causes inclusions to expand causing tiny fractures in the crystal surrounding them. It is a permanent and common Amethyst treatment and lasts forever. Most of the large darker stones exhibiting color zoning are often heat-treated to produce dramatic color changes.

Citrine from Amethyst

Citrine, yellow colored quartz though occurs naturally is produced by heating amethyst with the proper iron content under controlled conditions. It was discovered long ago that by heat-treating light colored amethyst or smoky quartz a small percentage would turn into attractive golden yellow color. The only difference between amethyst and citrine is the oxidation state of the iron impurities present in the quartz. When heated, the iron impurities are reduced to make amethyst's purple color to fade and turn yellow to reddish-orange (citrine). This process depends on various factors including the percentage of the iron impurities present and the heating duration and time. Much of citrine which comes from Brazil is heat-treated. Some unusual like golden orange or Rio Grande citrine or dark sherry colored or Madeira citrine are highly prized. On subsequent heating amethyst looses color and turns grey or white making it worthless.

Vermarine or Prasiolite

There is green quartz called 'Greened' amethyst or Vermarine also known as Prasiolite having light to medium color. It is produced by careful heating of Brazilian amethyst. A collector's item though inexpensive is not available easily. The heat treatment of Amethyst between 878 and 1382 degrees F may produce light yellow, red, brown, green or colorless varieties of stones. The result of heat treating these gems are stable so they hardly require any special care while wearing .But they should not be steam-cleaned due to their susceptibility to heat.

Irradiation

Sometimes irradiation an uncommon treatment is used to get unusual colors like clear green or dark/black smoky quartz. This process involves penetrating material with subatomic Gamma rays. These rays invade the electrons of the gems making them lose and captured by other atoms. It changes the light absorbing pattern and hence the change in the color. In the irradiated quartz crystal the color distribution would be more at the terminations and less at the roof. Through this process Amethyst can get its original purple color from the yellow citrine which re-oxidizes the iron impurities. This irradiation occurs either by synthetic means in the lab, or through natural radioactive decaying of minerals present in close vicinity. In most cases this is a reversible process. But excessive heat can change the distribution of the iron impurities within the quartz making it impossible to convert it back to amethyst.
