PARCEL OF 5 SMOKY QUARTZ SALMON BROWN ON AVERAGE 1,85CT GEMSTONES WITH ROUND CUT ONE BID TAKES ALL!
FIVE NATURALLY SMOKING 8,4CARAT (1,68G PLEASE SEE PHOTO MULTIPLY WEIGHT BY 5 TO GET CARATS AVERAGE 1,86CT) SALMON BROWN SMOKY QUARTZ GEMSTONES WITH A BEAUTIFUL ROUND CUT. ONE BIT FOR ALL! COMES WITH A PERSPEX PRESENTATION CASE.
DIFFERENT TO MOST OTHER GEMSTONES THE COLOR OF SMOKY QUARTZ IS NOT CREATED BY TRACE ELEMENTS BUT BY RADIATION! SMOKY QUARTZ GETS IT'S BLACK AND/OR SMOKY COLOR FROM NATURAL RADIATION FROM THE PROXIMITY OF OTHER RADIOACTIVE MINERALS IN THE GROUND. HENCE ALTHOUGH YOU WOULD THINK THESE GEMS LOOK LIKE THEY HAVE LOTS OF INCLUSIONS MOST ARE STILL ALMOST INCLUSION FREE.
THIS PACKET OF 5 SMOKY QUARTZ GEMS WITH A ROUND CUT DISPLAYS A BEAUTIFUL STAR BURST AFFECT DUE TO THEIR FACETTED CUT IN NATURAL LIGHT.
THIS PARTICULAR STONE WAS BOUGHT IN 2011 FROM A SELLER IN MOSSEL BAY SOUTH AFRICA WITH THE COUNTRY OF ORIGEN INDICATED AS BRAZIL. THEY HAVE A VVS (EYE CLEAR) CLARITY WHICH MEANS IT HAS NO INCLUSIONS AS SEEN WITH THE NAKED EYE WHICH IT APPEARS TO BE. IT WAS ALSO SOLD AS AN UNTREATED AND NATURAL QUARTZ GEMSTONES.
PASSED ALL THE TESTS PERFORMED:
PASSED THE SCRATCH TEST: IT DID SCRATCH A GLASS EASILY (YOU CAN TEST ALSO) WHICH WOULD INDICATE IT IS HARDER THAN GLASS. (MOHS HARDNESS GLASS 5.5-6.5 QUARTZ 7.0-7.5)
PASSED THE ELECTRON UV LIGHT EMISSION TEST: NO REACTION AS IT SHOULD BE FOR QUARTZ. GLASS AND ALL QUARTZ VARIETIES DOES NOT SHOW A UV AFFECT. (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 A LITTLE FROM STANDARD LEVEL 3 TO LEVEL 4. FOR QUARTZ A LEVEL OF 4 IS THE NORM FOR THIS TESTER. (WITH THIS TESTER GLASS MAKES NO MOVEMENT.)
SMOKY QUARTZ: Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.
Smoky quartz is a brownish grey, translucent variety of quartz that ranges in clarity from almost complete transparency to an almost-opaque brownish-gray or black crystals. While other crystals are colored by trace minerals, Smoky Quartz gets it's black and/or smoky color from natural radiation from the proximity of other radioactive minerals. While light-colored gems are always natural (so dont stress about synthetic smokies), some of the darker examples may be artificially enhanced by exposing the Quartz to radium or x-rays!
This particular Quartz variety forms in masses and crystal structures of all sizes. It can be found all over the world where the best specimens have come from Africa, Australia, and the New England region of the United States.
SIZE: 7x4,3mm (1); 8,1x4,9mm (3); 9,2x5,3mm (1)
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 PRELIMARARY TESTS ON EACH GEMSTONE.
PLEASE ALSO SEE MY OTHER ITEMS LISTED. I HAVE VARIOUS OTHER GEMSTONES ALSO ON AUCTION THIS WEEK. COPY THE URL UNDERNEATH AND PASTE INTO GOOGLE AND IT WILL TAKE YOU DIRECTLY TO ALL MY LISTINGS THIS WEEK. ALL MY AUCTIONS END AT 20H30 SO IT IS ADVISABLE TO PUT IN AN AUTOMATIC BID (HIGHEST PRICE YOU ARE WILLING TO PAY) EARLY.
