Kimberly Process Compliance – This is a registration and international tax process on all un-cut raw Rough diamonds that is shipped and/or transported through any means between sovereign nations. It has become mandatory law world wide through a United Nations campaign using as its basis what is referred to as “conflict diamonds”. The said goal was and is to theoretically prevent conflict (finance of war) through means of justifiable economic regulation of the “valuable diamond”. Legal compliance of the Kimberly Process is not optional. We do believe in “truth, justice and free enterprise” and enjoy promoting those ideals. There is no such thing as a “conflict diamond“, only conflict people. The phrase “conflict diamonds” is not good for the business. It gives people the wrong idea about gem quality diamonds in general which are primarily a symbol of eternal love and commitment.

This a topic that has been in the news. It will be discussed and dissected. Caution through education should be taken in order to avoid costly fines and major legal problems through non compliance. We will train you to be 100% compliant.

Social and humanitarian issues will be discussed in relation to various business environments. If you and your profitable business workings genuinely help and enhance people’s lives and there environment, you will create allies and be extremely successful.

There are certain diamond rich regions in the world that are “red flag” high risk places to be and to do business. Many of these locations are even Kimberly Process compliant on the rough diamond exports. The high risk creates opportunities and possible value added profit margins. The risk could be political instability, actual war, lack of a moral code among the local population, and by far the highest risk in the tropical locations is malaria, amoebic dysentery and other maladies. You must seriously consider and weigh all the factors. Consult your business advisers, mentors, friends and most importantly your family before committing to a move, project and/or a venture.

Education is Forever
