CVD testing is done in real time right in front of customers. One lot takes approx. 15-20 mins.
We try to test only 5-7 carats at a time in a single tray.

We test the diamonds for Natural or Lab grown . We also check if the test product is a simulant
like Moissanite or syntethic like American diamond or Cubic Zircon.

Labgrown diamonds are diamonds which are not mined from Earth (natural diamonds ) but are
created in a laboratory . There is a significant difference in price of Labgrown and natural
diamonds , natural diamond being expensive , therefore the need to get both tested .

Labgrown Diamonds are majorly created through 2 processes CVD and HPHT.

CVD: The CVD method places a diamond seed in a vacuum chamber. This chamber becomes filled with carbon-rich gases and is heated to nearly 1500 degrees Fahrenheit. The gas turns into plasma from these extremely high temperatures, causing the release of carbon pieces. These carbon pieces become layered onto the diamond seed, which grows the diamond.

HPHT: The HPHT method is the original method of creating lab-grown diamonds. HPHT process can also be used to enhance the color of diamonds to make them colorless, pink, green, blue, or yellow.

To grow an HPHT diamond, a small diamond seed is placed in carbon, the element that diamonds are made of. The diamond seed is exposed to extreme heat and pressure, replicating the way diamonds are naturally grown underground by the earth. The diamond seed is exposed to temperatures of over 2,000 degrees Fahrenheit and pressure of about 1.5 million PSI (pounds per square inch). The carbon melts and forms a diamond around the seed. It is then cooled and the diamond is formed.

No CVD and HPHT can only be detected by screening them through various lights in machines.
They cannot be detected by looking through an eyeglass

We do not check diamonds for filling. Filling is molten glass that is filled in feather or fissure
of the diamond. Filling cannot be checked in CVD screening machines.

CVD can be tested on mounted jewellery.

CVD/HPHT testing is done through Screening the diamond or jewellery through various lights
. There is no chance of diamond or jewellery getting damaged or there being change of any
characteristics in the diamond or jewellery.

No, we specialize only in testing only diamonds .

No , we do not provide gold testing services . We provide only diamond testing services .

We provide Natural/ Labgrown testing certificate for solitaire diamonds . Testing certificate is
not provided for testing loose diamonds or parcels . It can be provided on request .

Jewelscan HD follows stringent processes religiously , where we first weigh the diamonds in
a Mettler weighing scale , then test the diamonds by first screening through various lights .
Then diamonds are tested for Synthetic or simulant. Lastly diamond is checked by an industry
experienced expert. A hologram certificate is then issued and diamonds are given back to
customers in a sealed envelope. All this process is done right in front of the customer where
the customer can verify the diamonds at any stage. The authentication seal ensures security of
the diamond if the customer sends a staff or a representative.
In order to ensure tracking of latest trends in CVD /HPHT Jewelscan HD keeps upgrading its
software from time to time . We keep researching on newer versions of CVD and get our results
tested and verifies at the most reputed and Sophiticated laboratories all across the country .

No , Charges for testing are fixed and not negotiable . We do provide pre paid packages for
bulk testing for our customers at very affordable prices . Customers can get the diamonds tested
any number of times over the validity period upto the caratage purchased.

-Still Gemstone and Jewellery Photography with various background options
- 180 degree videography with contolled light environment in customer required format
- 360 degree videography with contolled light environment in customer required format

- No , we donot provide onsite photography / videography services as our photography is done
in a controlled light environment created in a dedicated hi-tech machine which provided exact
same photo quality and consistant light characteristics everytime .

No , We do not provide model based photography services right now .
