THE DIAMOND FACTS

“ The diamond industry is vital to the Southern African economy.” — Nelson Mandela

  • 65% of the world’s diamonds come from African countries

  • Approximately $8.5 billion worth of diamonds a year come from African countries

  • Approximately 5 million people have access to health care due to diamond revenues.

  • An estimated 10 million people globally are directly or indirectly supported by the diamond industry.

  • Revenues from the diamond industry help provide necessary counseling, testing, education, treatment programs, clinics and hospices for HIV/AIDS patients.

  • Conflict diamonds have been reduced since the implementation of the Kimberley Process in 2003.

WHAT ARE CONFLICT DIAMONDS?

  • Conflict diamonds are diamonds illegally traded to fund conflict in war-torn areas, particularly in central and western Africa

  • The United Nations (UN) defines conflict diamonds as

  • "...diamonds that originate from areas controlled by forces or factions

  • opposed to legitimate and internationally recognized governments”

  • The diamond industry estimates that conflict diamonds represent 4% of the total

  • trade in rough diamonds. Others have estimated that conflict diamonds could

  • amount to as high as 15% of the total trade.

THE KIMBERLEY PROCESS

  • Certification scheme to control movement of diamonds across borders

  • Runs on consensus only – unique, but fragile too (SA played strong role in creation)

  • Conflict and illicit diamonds not the same - KP mandate is ‘conflict diamonds’

  • Several working groups making up the KP core; chaired annually by member states in rotation (Israel was the KP chair in 2010 and the current chair is the DRC)

  • The Working Group of Diamond Experts (WGDE) represented by the South African Diamond and Precious Metals Regulator, with Mintek participation at their request

  • WGDE often asked to review controversial parcels – current decisions based on shape / colour / surfaces : risky and qualitative

  • SADPMR-Mintek Diamond Provenance Laboratory aims to develop a forensically sound method for KP and SA

MINTEK DIAMOND PROVENANCE PROJECT

  • Diamond provenance seeks to identity the origin of a diamond by comparing diamond characteristics  to profiles for different sources

  • Mintek and the SA Diamond and Precious Metals Regulator (SADPMR) have

  •      launched a project in 2009 to study the possibilities of determining the origin of

  •      rough diamonds

  • The heart of the project is a new laboratory facility in Mintek's Mineralogy division,  funded by the SADPMR, which is using a two pronged approach by studying the physical as well as chemical characteristics of gem-quality diamonds

  • The lab is equipped with a state-of-the art equipment including a Laser Ablation Inductively Coupled Plasma Mass Spectrometer (LA-ICP-MS) for trace element measurements

  • Diamond provenance will be useful for the purpose of identifying conflict diamonds

THE SCIENCE BEHIND…………………DIAMOND THEORY

Diamonds are composed chiefly of the element carbon – but can also contain nitrogen and tiny amounts of “trace elements”

OBJECTIVES OF THE PROJECT

  • Build a SADC database from mainly alluvials, characterising shape, colour, surface features, breakage, infrared spectra, trace elements

  • Develop a forensic method for diamond provenance, and ascertain if this can be used for discrimination

  • Emphasis on real production type samples – gems not coated stones / boarts etc.

  • Control ABSOLUTELY the provenance of the samples

  • Share information with sample providers and the scientific community

  • Build local skills and methods with all interested parties

WHERE ARE WE NOW?

  • A standard procedure for diamond characterization has been developed

  • Ten parcels of diamonds from various African localities have been fully characterized and the results analyzed

  • Indications that subtle but distinct variations can be made between diamond parcels and that homogeneity exists in the diamond parcels

  • Extension of the dataset is in progress: only with large numbers of characterized stones can we determine whether diamond discrimination can be a viable forensic process


Slide13 l.jpg

MINTEK GOING FORWARD

  • Approach diamond origin in a holistic manner :

    • Building a comprehensive database to evaluate the source of diamonds

    • Greater volumes of stones from different sources will be used to really comprehensively build up the database

    • These will be used to further assess diamond discrimination potential.

    • The knowledge gained in this study will be used for application with other conflict minerals
