BLOOD RED 1.0CT RUBY GEMSTONE - UV STRONG RED! HIGH THERMAL CONDUCTIVITY! HEAT TREATED!

ONE OF MY LAST RUBIES SO YOU MIGHT WANT TO BID ON THIS ONE! A BEAUTIFUL 1,0CT (0,20G SEE PHOTO PLEASE MULTIPLY GRAM BY 5 TO GET CARATS) REAL (SYNTHETIC OR LAB MADE) RED RUBY GEMSTONE WITH A OVAL CUT.
 
THIS PARTICULAR STONE WAS BOUGHT IN 2011 FROM A SELLER IN BANGKOK THAILAND. COUNTRY OF ORIGEN WAS INDICATED AS AFRICA. IT WAS INDICATED AS A NATURAL RUBY THAT WAS HEAT TREATED (TYPE OF HEAT TREATMENT NOT INDICATED). IT HAS A SI CLARITY (INCLUSIONS EYE VISIBLE) WHICH IT APPEARS TO BE AT FIRST GLANCE.
 
IT IS INDEED A REAL RUBY GEMSTONE (EVEN THOUGH SYNTHETIC OR LAB GROWN) AS IT PASSED ALL THE TESTS I COULD PERFORM:
PASSED THE SCRATCH TEST: IT SCRATCHES GLASS IT IS HARDER THAN GLASS. THIS INDICATES THIS GEMSTONE IS NOT GLASS BUT A REAL MINERAL GEMSTONE. (MOHS HARDNESS GLASS 5.5-6.5 RUBIES 9.0)
PASSED THE ELECTRON UV LIGHT EMISSION TEST: GIVES A STRONG RED FLUORESCENCE UNDER UV LIGHT. NATURAL RUBIES USUALLY SHOW WEAK RED FLUORESCENCE. A SYNTHETIC RUBY USUALLY SHOWS A STRONG RED FLUORESCENCE. OUR RUBY SHOWS A STRONG RED FLUORESCENCE (PLEASE SEE PHOTO) THAT WOULD INDICATE IT IS A SYNTHETIC RUBY!
(THE UV LIGHT HIT THE ELECTRONS. THEY JUMP AND FALL BACK. THEY RADIATE LIGHT OF A CERTAIN WAVELENGTH WHEN THEY DO WHICH IS SPECIFIC TO EACH ELEMENT IN THE MINERAL. THIS IS CALLED FLUORESCENCE. ONLY 10% OF GEMSTONES EXHIBIT A FLUORESCENCE AFFECT LIKE RUBIES, SAPPHIRE, TOPAZ, OPALS AND DIAMONDS. GLASS AND ALL NATURAL QUARTZ VARIETIES DOES NOT SHOW A UV AFFECT.)
PASSED THE THERMAL CONDUCTIVITY TEST: TESTED THE THERMAL CONDUCTIVITY WITH A MIZAR PRESTIGE SERIES 2 DIAMOND TESTER. IT MOVED UP THE LADDER FROM STANDARD LEVEL 3 TO LEVEL 6. FOR SAPPHIRES AND RUBIES A LEVEL OF 6 TO 7 IS THE NORM FOR THIS TESTER.
(WITH THIS TESTER GLASS, TANZANITE, TITANITE AND TOURMALINE MAKES NO MOVEMENT, AQUAMARINE AND EMERALD LIE INBETWEEN AND CAN GIVE A LEVEL OF 3 OR 4. QUARTZ , GARNETS, SPINELS AND KUNSITE GIVES A THERMAL OF 4, TOPAZ GIVES A THERMAL OF 5. RUBIES AND SAPPHIRE GIVES A THERMAL OF 6 TO 7.)
 
MY PERSONAL CONCLUSION REGARDING THIS GEMSTONE:
THIS RUBYS THERMAL CONDUCTIVITY IS HIGH AND PUT IT IN THE CONUNDRUM (MINERAL OF RUBY AND SAPPHIRE) RANGE. IT HAS A STRONG UV FLUORESCENCE WHICH MOST PROPABLY INDICATES IT IS A SYNTHETIC OR LAB MADE RUBY. IT IS HOWEVER A REAL GEMSTONE AND EVEN IF SYNTHETIC IT SHARES VIRTUALLY ALL CHEMICAL, OPTICAL, AND PHYSICAL CHARACTERISTICS OF ITS NATURAL MINERAL COUNTERPART. IT HAS A SI CLARITY (INCLUSIONS EYE VISIBLE) WHICH WOULD SUGGEST IT CAN BE A NATURAL RUBY AS MOST LAB MADE RUBIES APPEARS FLAWLESS WITH NO INCLUSIONS EYE VISIBLE. MY CONCLUSION:  IT IS RUBY BUT UNCLEAR IF NATURAL HEAT TREATED OR LAB MADE.
 
SIZE: 7.1mm x 5.2mm x 3.0mm
 
DISCLAIMER: I AM NO GEMSTONE EXPERT AND COULD PERFORM ONLY A LIMITED NUMBER OF PRELIMARY TESTS (SCRATCH TEST; UV TEST; THERMAL TEST) THAT I COULD CONFIRM SOME OF 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 ON EBAY AND OTHERS BY TRAVELLING TO OTHER COUNTRIES. RUBY GEMSTONES CAN BE SYNTHESIZED AND ADVANCED INSTRUMENTS ARE NEEDED TO INDICATE IF NATURAL OR LAB MADE.
 
RUBIES: Firstly Rubies is one of the four precious gemstones amongst Saphire, Diamond and Emerald. Real rubies rank 9 on the Mohs scale of Hardness.
Ruby is a red type of the corundum mineral, along with sapphire. Sapphires have each color of the corundum, except red, which is the color of the ruby. Corundum is relatively common in nature, and is completely colourless. Chromium causes the red colour in rubies.
Corundum once found wide application as an industrial abrasive like sandpaper. Gem corundum is mined almost exclusively from gem gravel deposits. Historically, production has been from Myanmar (Burma), Thailand, India and Sri Lanka (Ceylon). Rubies are known as the King of Gemstones and Myanmar and Thailand honor the corundum ruby as their national stone. More recent important sources include East African countries of Madagascar, Tanzania and Mozambique.
The color and clarity of rubies and sapphires is commonly enhanced by heat treatment. This is today the rule rather than the exception. 
 
SYNTHETIC GEMSTONES: A synthetic gem material is one that is made in a laboratory, but which shares virtually all chemical, optical, and physical characteristics of its natural mineral counterpart.
In the late 1800s, ruby became the first gem to be created in a laboratory by Auguste Verneuil. In 1902, he announced the development of his flame-fusion process for synthesizing this beautiful gem. Synthetic rubies and sapphires are presently manufactured in enormous quantities for both industrial and gem application. Synthetic corundum, which includes ruby and sapphire, can be made by the greatest number of processes. Because of this, synthetic corundum is available at many price levels, from very affordable to very expensive. 
Synthetic Gemstones are still real gemstones and since often free of inclusions can appear more beautiful than natural gemstones. On the market it sells for approximately a 30% discount to the natural gemstones which makes them still very exspensive.
