HOW STRANGE? A LARGE MANMADE 24.34CARAT GREEN AMETHYST GEMSTONE WITH BEAUTIFUL CUSHION CUT

HOW STRANGE? A GEMSTONE CALLED GREEN AMETHYST. EVERYBODY KNOWS AMETHYST IS PURPLE.
"Green amethyst" is actually "green quartz." Amethyst itself is purple quartz. This green quartz is either created from heat treating some varieties of quartz, mostly amethyst or lab grown from some Quartz fragments. This association seems to permit the use of the misnomer. Green heat-treated quartz has its own name, "Prasiolite." Which nobody is familiar with.
 
AN AWESOME LARGE 24.34 CARAT GREEN QUARTZ GEMSTONE WITH A BEAUTIFUL CUSHION FACETTED CUT. The cushion cut, also called the pillow cut, is essentially a square with rounded corners and sides, like the cushions of a couch. COMES WITH A BEAUTIFUL PERSPEX PRESENTATION CASE AND VELVET BAG.
 
THIS PARTICULAR STONE WAS BOUGHT FROM A SELLER IN THAILAND WITH THE COUNTRY OF ORIGEN INDICATED AS BRAZIL. IT HAS A VVS (EYECLEAR) CLARITY WHICH MEANS IT IS FREE OF INCLUSIONS AS SEEN WITH THE NAKED EYE WHICH IT APPEARS TO BE. IT WAS ALSO SOLD AS AN MAN MADE QUARTZ GEMSTONE.
 
SIZE: 19.45 x 16.62 x 11.17mm
 
DISCLAIMER: I AM NO GEMSTONE EXPERT. THESE GEMSTONES BELONGED TO A FAMILY MEMBER THAT HAS PASSED AWAY. HE COLLECTED GEMSTONES DURING THE EARLY TWENTY FIRST CENTURY MANY WERE BOUGHT ON EBAY AND OTHERS BY TRAVELLING TO OTHER COUNTRIES. I HAVE TRIED TO VERIFY AS FAR AS POSSIBLE ANY STATEMENTS OR CLAIMS BY DOING SOME THOROUGH RESEARCH ON EACH GEMSTONE.
 
AMETHYST:
In antiquity, the most valuable gems were known as the cardinal gems that included Diamond, Emerald, Ruby, Sapphire and Amethyst. These were the gems most valued for their rarity.
Amethyst no longer appears on this list. What happened? The answer is that extensive amethyst deposits were discovered in South America in the early 19thcentury, and Amethyst was no longer regarded as a rare gem.
Historically, fine Amethyst came from the Ural Mountains in Russia and in Germany. Both of these deposits are now exhausted. Very large deposits were discovered in southern Brazil in the early19th century, with subsequent discoveries in nearby Uruguay. In the 1950's high quality amethyst was found in Zambia. The Zambian Amethyst has acquired the reputation as some of the finest in the world due to its unusually rich color. However, the Zambian amethyst is mainly found in smaller sizes, with stones over 10 carats counting as very rare.
Amethyst occurs in primary hues from a light pinkish violet color to a deep purple color. Many amethyst collectors search out the deepest purples they can find. But while the darker purples are highly prized, you will find they are not as sparkly as the slightly lighter stones.
For a gem which was once regarded as precious as Sapphire, Amethyst is very affordable, even at the higher grades. Prices for high quality cut stones are typically in the range of $20 to $30 per carat, with particularly fine pieces around $40 per carat.
Most fine Amethyst is very clean and completely untreated and can be found in large sizes. It's quite a durable gem and is suitable for all kinds of jewelry.
 
VALUE (THE 4CS COLOR CUT CLARITY CARAT):
THE PRICE OF ANY GEMSTONE DEPENDS ON THE RARITY OF THE4CS. COLOR, CUT, CLARITY, CARAT.
 
COLOR: Color is the most important factor for amethyst. The rich purple hue of Amethyst retains its allure, and gem collectors still seek out particularly fine specimens. For the fact is, despite the large volume of purple quartz mined in South America -- hundreds of tons per year -- the vast majority of it is commercial grade material with a less saturated color. Fine deep purple Amethyst is still fairly rare, though not especially expensive. OUR SAMPLE IS OF COURSE A LITTLE DIFFERENT AND HAS THE PURPLE CHANGED INTO A BEAUTIFUL SOFT GREEN. I ASSUME NOT TOO RARE SINCE IT IS MAN MADE.
 
CUT: As with any gem material, custom cutting increases value. In many fancy cut or carved specimens, most of the value is due to the artistry of the cutting. OUR STONE HAS WHAT IS CALLED A CUSHION CUT OR PILLOW CUT.
 
CLARITY: As regards to Clarity Inclusions will decrease value. OUR STONE IS RATED AS VVS (EYE CLEAN) The Gem in the interior and on the surface is free from inclusions of any kind as seen by the naked eye.
 
CARAT: Theres no exponential increase in value per carat with increase in size, as larger sizes are readily available. OUR STONE IS 24.34CARAT.
