Prasiolite Faceted Baguette - 19 X 9.3 mm Genuine Natural Faceted Gemstone

...you decide what this gemstone will become.

OK, folks *sigh* Prasiolite is NOT "Green Amethyst" - it is a green variety of quartz, aka: Vermarine.

****WARNING: Soap Box standing about to commence! Skip to below the line if you want to miss my rant ;-)
*Shakes fist at self for long-winded ranting*

Green Quartz is often incorrectly called Green Amethyst, which is a misnomer and not an acceptable name for the material, the proper terminology being Prasiolite. It is actually against Federal Trade Commission Guidelines to call Prasiolite Green Amethyst.

Prasiolite (spelled with an “i” and sometimes spelled praziolite) comes from the Greek word meaning “Leek Stone” and is sometimes also incorrectly called Lime Citrine. It is a green variety of quartz. It is both a naturally occurring gemstone, and also simulated via heat treatment of quartz.

[[[Praseolite (spelled with an “e”) is a heat-treated, leek-green color of cordierite/Iolite - which is a completely different species from prasiolite/vermarine/quartz but it does have a similar leek-green (greenish to greenish yellow) in color.]]]

The natural Prasiolite green variety quartz - Prasiolite/Vermarine is a naturally occurring greenish yellow gemstone. It is speculated that heat produced naturally by geological events during formation of the mineral caused the production of the naturally green deposits. Deposits of naturally occurring Prasiolite are often found side-by-side with purple Amethyst crystals in igneous, metamorphic and volcanic rock. [NOTE: Natural Prasiolite can also be enhanced to improve the color.]

Heat-treated green variety quartz - Is an artificially induced, heat-treated Amethyst that the Prasiolite name is applied to - IT IS AMETHYST, which contains iron compounds Fe2 - it turns a pale to very pale grayish mint green after heating. THIS should be labeled "Green Amethyst" or "Greened Amethyst", or better yet, "heat-treated Amethyst" or "enhanced Quartz". Either way, this heat-treated 'prasiolite'/green variety of quartz is not considered rare nor scarce. There is also an inexpensive irradiated form available too.

It is very difficult to separate the heat-treated Quartz from the naturally green Prasiolite. Both the enhanced Quartz (Greened Amethyst) and natural Prasiolite materials are almost identical in properties.
"In addition to the generic healing properties of Quartz, the Green Quartz or Prasiolite variety, opens and stabilises the heart chakra. It promotes an intuitive capability which is coupled with love. Prasiolite is a stone of tranformative energies. It transmutes negative energy to positive without releasing it to the atmosphere. Prasiolite inspires creativity, attracting success, prosperity and abundance; and aids the endocrine glands, helping to keep the body balanced." - quoted from internet source
