GIA Diamond Origin Report

Ever wonder where your diamond comes from?
Is it ethically & responsibly sourced?

Does it provide a positive impact on its surrounding community? Wonder No More!!! OCG is able to offer  GIA Graded loose polished diamonds that are accompanied by a Diamond Origin Report. After purchasing a diamond from us, you can download the GIA Diamond Origin app onto your phone/tablet to access further information.   
The GIA diamond grading report that is based on GIA’s ground-breaking research and scientifically matches a polished diamond to its original rough to confirm the country of origin. In addition to a quality assessment of the diamond, the GIA Diamond Origin Report tells each diamond’s story… including how that diamond provided benefits to the local communities it passed through.
Benefits like infrastructure improvements, educational opportunities and healthcare for the people where it was mined.
Once the app is installed, scan the barcode on the GIA smart card and all the information (including videos & pictures) pertaining to that particular diamond becomes available.
