Hi there

The 3 main organisation for grading diamonds and providing a certificate are:

Gemological Institute of America (GIA)
http://www.gia.edu/
Antwerp World Diamond Centre (HRD)
http://www.hrd.be/
International Gemological Institute (IGI)
http://www.igi-usa.com/

As someone has already mentioned, diamonds are graded on the 4Cs; carat, cut, clarity, and colour. Any of the above 3 organisations will grade the diamond against the 4Cs, however each organisation is slightly different ....this link gives some great advice on their differences http://www.bestdiamonds.co.uk/diamond_faq.asp

You can also get a free appraisal form any specialist diamond company. I am sure you will find one in the nearest large city to where you live. These specialist companies will be able to give you a fairly good indication of the diamonds 4Cs without taking it to the GIA, IGI, or HRD, they will also give you an extimate value of the diamond.

Finally, if you feel your diamond is likely to be of high value you may also want to have it "finger printed" by Gemprint (a USA based company) , they fire a laser through the diamond to take a unique print and store this in a database against the owner's details - good for insurance against theft of someone switching your diamond.


I hope this helps

Assuming you mean a cut gem-quality diamond, there are specialist centres which grade diamonds and issue certificates based on the "four 'C's" of diamond quality:

- cut
- colour
- clarity
- carat weight

Grading is carried out by GIA in USA and HRD in Belgium, among others, based on the above criteria.

a few easy things you could do would be trying to cut glass with one of its corners, or take it to a jewler and they can tell.

if it can scratch anything, it's real. and also, try shining blacklight (UV) on it. if it doesnt shine blue of purple, it's real. :D
