Manufacturing & Rough

We procure rough from the deep mines in Russia which are then hand-cut and hand-polished in combination with high-end technology to deliver diamonds with perfect proportions and incomparable lusture.

Our close longstanding relationship with Russia empowers us to source and distribute variety of high quality and natural diamonds at the most competitive prices. All ‘NIMA’ diamonds have Kimberly Process Certificates which means that they have been purchased from ethical sources not involved in funding conflict.

‘Nima’ diamonds are made to the highest possible international standards and come with GIA, HRD and IGI certification. Our customers can be rest assured that when they buy a ‘Nima’ Diamond, it was mined and procured from the most legitimate source.


The KPSC was established in 2003 as a joint government, non- government and international diamond industry initiative to eliminate the flow of conflict diamonds. The scheme was initiated to clean the diamond trade from conflict diamonds sold by rebel group or their allies to fund wars against legitimate government. Fifty-four participants representing 81 countries participate in the KPSC ensuring a more transparent and secure system for import and export of rough diamond.

We at Nima deal with suppliers who strictly adhere to KPSC. All import and export of rough diamonds have a Kimberly Process certificate attesting that the diamonds were procured from a legitimate source.
