GISA CERTIFIED STRONG GREEN EMERALD 1.13CT GEMSTONE WITH INCLUSIONS! PLEASE READ FULL DESCRIPTION!

STRONG GREEN NATURAL EMERALD 1.13CT GEMSTONE (0,22G PLEASE SEE PHOTO MULTIPLY WEIGHT BY 5 TO GET CARATS). IT HAS EYE VISIBLE INCLUSIONS! WHY IS THIS IMPORTANT? THE ONLY WAY TO DISTINGUISH BETWEEN SYNTHETIC AND NATURAL EMERALDS WITHOUT LAB EQUIPMENT IS TO LOOK FOR INCLUSIONS.
 
THIS PARTICULAR STONE WAS BOUGHT IN 2011 BY A DECEASED FAMILY MEMBER. THE SELLER AND THE COUNTRY OF ORIGEN WAS NOT INDICATED. IT HAS A SI2 CLARITY (INCLUSIONS EYE VISIBLE) WHICH MEANS YOU CAN SEE SOME INCLUSIONS WITH THE NAKED EYE. IT WAS ALSO SOLD AS A NATURAL EMERALD GEMSTONE.
 
DISCLAIMER: I AM NO GEMSTONE EXPERT AND THERE ARE NO TESTS (SCRATCH TEST; UV TEST; THERMAL TEST) THAT I COULD PERFORM ON EMERALD THAT CAN CONFIRM THIS GEMSTONES NATURE AND PROPERTIES. THIS GEMSTONES BELONGED TO A FAMILY MEMBER THAT HAS PASSED AWAY. HE COLLECTED GEMSTONES DURING THE EARLY TWENTY FIRST CENTURY MANY WERE BOUGHT ONLINE LIKE EBAY AND OTHER WHILE TRAVELLING TO OTHER COUNTRIES. EMERALD CAN BE SYNTHESIZED AND ADVANCED INSTRUMENTS ARE NEEDED TO DISTINGUISH NATURAL FROM CREATED EMERALD AND OTHER GEMSTONES.
 
THIS EMERALD GEMSTONE HAS A SUPPLIED GISA (GEMMOLOGY INSTITUTE OF SOUTHERN AFRICA) CERTIFICATE. THIS COMPANY COULD NOT BE CONTACTED BY CONTACT DETAILS SUPPLIED ON THE BACK AND THERE IS NO WEBSITE TO CHECK PAST REPORTS THAT I COULD FIND. I DO NOT KNOW IF STILL IN EXISTENCE. TO THEIR CREDIT THOUGH I HAVE SEEN REPORTS BY THEM WHICH WHERE BY MY OWN CONFIRMATION CORRECT.
 
THIS EMERALD GEMSTONE GAVE THE FOLLOWING RESULT ON THE TESTS I COULD PERFORM:
PASSED THE SCRATCH TEST: IT SCRATCHES GLASS EASILY IT IS HARDER THAN GLASS.
(MOHS HARDNESS GLASS 5.5-6.5 EMERALD 7,5-8,0)
THE THERMAL CONDUCTIVITY TEST: TESTED THE THERMAL CONDUCTIVITY WITH A MIZAR PRESTIGE SERIES 2 DIAMOND TESTER. SOME AREAS DID NOT MOVE AND STAYED ON LEVEL 3 WHILE OTHER AREAS MOVED UP THE LADDER FROM STANDARD LEVEL 3 TO LEVEL 4. FOR BERYL A LEVEL OF BETWEEN 3 AND 4 IS THE NORM FOR THIS TESTER WITH ITS THERMAL CONDUCTIVITY OF 0.013.
(WITH THIS TESTER GLASS 0,002, TANZANITE, TITANITE AND TOURMALINE MAKES NO MOVEMENT, AQUAMARINE AND EMERALD LIE INBETWEEN AND CAN GIVE A LEVEL OF 3 OR 4. QUARTZ 0,026, GARNETS, SPINELS 0,028 AND KUNSITE GIVES A THERMAL OF 4, TOPAZ 0,04 GIVES A THERMAL OF 5. RUBIES AND SAPPHIRE 0,08 GIVES A THERMAL OF 6 TO 7.)

EMERALDS:
Emerald is the varietal name for the green variety of beryl, a mineral also known for its gold yellow and blue varieties (heliodor and aquamarine, respectively).
The first known emerald mines were in Southern Egypt as early as 330 BC, and served mainly to feed Queen Cleopatras love of the gem. It was also associated with the Greek goddess Venus, who represented love and beauty.
EMERALDS ARE HIGHLY VALUABLE DESPITE THE FACT THAT MOST ARE SATURATED WITH TINY MINERAL INCLUSIONS REFERRED TO AS JARDIN. Flawless emeralds are rare and extremely valuable. THE NAME EMERALD COMES FROM THE GREEK SMARAGDOS AND REALLY JUST MEANS GREEN GEMSTONE.
The colors in beryl gems do not occur until traces of some other element are added. Iron adds beautiful sea-blue hues, resulting in aquamarine and a different iron ion adds yellow gold to form Heliodor. In the case of the emerald, it is mainly traces of chromium and vanadium which are responsible for the vibrant green color.
Emerald has a good hardness of 7.5 to 8 on the Mohs scale, which makes it appropriate for rings, but the gem can be brittle, and its many fissures can make cutting, setting and cleaning rather difficult. Thus, the emerald cut, a rectangular or square cut with bevelled corners that brings out the beauty of the gem and at the same time protects it from mechanical strain. 
Today, some of the finest stones come from Colombia, which has about 150 known deposits. Zambia, Zimbabwe and Brazil have a reputation for fine emeralds in the international trade. Emeralds are also mined in Madagascar, Pakistan, Afghanistan and Russia.
 
LAB CREATED EMERALDS AND DYED COLOR-ENHANCED EMERALDS
Lab-grown emeralds created under the same conditions and with the same materials as emeralds found in nature but in a vastly reduced time frame. They are also a lot cheaper. However not even dealers can distinguish between natural and synthetic ones without looking inside the emeralds. SYNTHETIC ONES HAVE ALL THE SAME CHEMICAL AND VISUAL PROPERTIES OF EMERALDS, AND THE ONLY WAY TO DISTINGUISH BETWEEN THEM AND NATURAL EMERALDS WITHOUT LAB EQUIPMENT IS TO LOOK FOR INCLUSIONS. Lab created emeralds are beautiful and near perfect inclusions free. Most natural emeralds will have inclusions.
Today, many emeralds are enhanced with colourless oils or resins. This is a general trade practice. Emeralds are also occasionally color-enhanced by introducing dye into surface reaching fissures to deepen the green color of less valuable lighter Emeralds.
