GORGEOUS 5,65CT CBROWNISH ORANGE IMPERIAL TOPAZ GEMSTONE WITH BEAUTIFUL PEAR CUT

AN AWESOME LARGE 5,65CT (1,13G PLEASE SEE PHOTO MULTIPLY WEIGHT WITH 5 TO GET CARATS) BROWNISH ORANGE IMPERIAL TOPAZ GEMSTONE WITH A BEAUTIFUL PEAR CUT. COMES WITH A SMALL PERSPEX PRESENTATION CASE.
 
THIS PARTICULAR STONE WAS BOUGHT INN 2011 FROM A SELLER IN CHANTHABURI THAILAND WITH THE ORIGEN OF THE STONE INDICATED AS AFRICA. IT HAS A VS (EYE CLEAR) CLARITY WHICH MEANS IT HAS SLIGHT INCLUSIONS BUT IT CANNOT BE SEEN WITH THE NAKED EYE WHICH IT APPEARS TO BE. IT WAS ALSO SOLD AS A NATURAL UNTREATED IMPERIAL TOPAZ GEMSTONE.
 
I THINK IT MIGHT WELL BE A NATURAL GEMSTONE THAT HAS BEEN HEAT TREATED THOUGH. I SAY THIS BECAUSE COMMON TOPAZ IN ITS NATURAL STATE IS COLORLESS, THOUGH TRACE ELEMENT IMPURITIES CAN IN RARE INSTANCES MAKE IT PALE BLUE OR GOLDEN BROWN TO YELLOW ORANGE. TOPAZ IS OFTEN TREATED WITH HEAT OR RADIATION TO MAKE IT A DEEP BLUE, REDDISH-ORANGE, PALE GREEN, PINK, OR EVEN PURPLE.
 
TESTS PERFORMED:
PASSED SCRATCH TEST: IT DID SCRATCH A GLASS WINDOW PANE EASILY WHICH WOULD INDICATE IT IS HARDER THAN GLASS. (MOHS HARDNESS GLASS 5.5-6.5 TOPAZ 8.0)
PASSED UV LIGHT TEST: NO UV REACTION.
EXSPECTED UV REACTION IS NO TO WEAK FOR TOPAZ IN GENERAL. NATURAL SHERRY-BROWN, PINK, OR GOLDEN YELLOW TOPAZ MAY SHOW A WEAK TO STRONG ORANGE-YELLOW FLUORESCENCE.
(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 5. FOR TOPAZ A LEVEL OF 5 TO 6 IS THE NORM FOR THIS TESTER.
(WITH THIS TESTER GLASS NO MOVEMENT AND QUARTZ ONLY MOVE UP LITTLE TO NO 4.)
 
SIZE: 9,8mm x 13,9mm x 6,0mm
 
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 AND PRELIMERARY TESTS ON EACH GEMSTONE.
 
TOPAZ:
Topaz is a semi-precious gemstone formed from magma deposits. Chemically its made up of silicone, aluminum, and fluoride. Today, topaz deposits are found in Brazil, United States, Madagascar, Myanmar (Burma), Namibia,  Zimbabwe Mexico, Sri Lanka, Pakistan, Russia, and China.
Common topaz in its natural state is colorless, though trace element impurities can in rare instances make it pale blue or golden brown to yellow orange. Topaz is often treated with heat or radiation to make it a deep blue, reddish-orange, pale green, pink, or even purple.
Blue topaz, the most common variety seen in jewelry today, has been produced in such quantities that is has essentially dropped the price of the natural blue down to that of the treated stone.
Natural topaz is found as crystals that are considerably larger than those of many other precious stones. Consequently, its per-carat price does not rise much as the size of the gem increases.
