Bahia (Brazil) diamonds – Andaraí, Chapada Diamantina

Brasil Diamantina Andarai Lençois 2004 03 127
Diamonds in Andaraí (Chapada Diamantina), BA-Brazil

Travelling with a friend a couple of years ago in the Brazilian hinterland, I had the opportunity to photograph diamond parcels from several locations. This photo was captured in Andaraí, Chapada Diamantina, Bahia.

The region is a classical diamond producing area that has seen its heyday several decades ago, especially during WW II; current diamond garimpo is very limited. Diamonds in this area are characterised by the presence of carbonado (a variety of microcristalline diamond; a dark rock made of tiny diamond crystals, its origin being speculated as resulting from a meteorite impact), a feature in common with Central African Republic diamonds.

The smiling future of jewellery according to McKinsey & Company

Economic Geology should go outside its classical bounds of the mineral deposit, explore new paths and, at least, acknowledge what the users of the minerals we unearth are doing. Mckinsey just released a short report on the future of jewellery: A multifaceted future: The jewelry industry in 2020. For those in the gems and precious metals, it might anticipate (at least partially) the trends in mining and exploration of these resources.

It’s an interesting view with a smiling perspective; do you share it? Or will it face increasing budget competition and threat from new offers (hi tech communication, travel and exotic experience) in the new generations? Is expensive (diamond) jewellery a good hedge against economic downturns in today’s chaos? Or is it just unfashionable expensive glass?

Diamonds from Diamantina – MG, Brazil

DSC_0104
A rare feature – hexagonal pitting

Diamonds occur in many colours, shapes, sizes and transparencies. Sometimes they just look like sand (well, expensive, very expensive sand, as a lowly 10 USD/carat stone is worth more than gold – currently hovering 1.200 USD/oz); or else diamonds may be broken (chips), dotted in the inside with other minerals, eroded or pitted at the surface, colourless, slightly tinted or, rarely, fancy (marked tints).

The rough diamonds in this parcel are from the Diamantina region (Jequitinhonha river) in Minas Gerais (Brazil). This is an historic diamond district, originally found and discovered in the early 17th century during Brazil’s colonial period. Diamonds in the area tend to have a greyish tint; alas, this is not their body color (as they would be extremely rare and expensive), just the color of a shallow coating probably due to radiation.

This photo illustrates a rare diamond feature caught by chance on camera. Note the focused diamond on the right hand side; it has a triangular shape (locally know has chapéu de frade). On the center of the diamond there is a depression of rare hexagonal shape, unlike trigons diamond’s characteristic inverted pyramidal pits.

One century of Angolan diamonds – a report

One century of Angolan diamonds

After many months of hard work, the report was released.

The report organizes information about the Angolan diamond industry (the deposits, the mines and prospects, the global market, regulatory and economical settings and the key institutions). This information was previously either disperse, unpublished or only available in Portuguese language sources.

” Angolan diamonds have been known for 100 years. These diamonds are famed for their high quality and high value and have attracted expert buyers from all over the world, from the giant De Beers (the exclusive buyer for many decades) to the smaller scale traders. The country is endowed in both kimberlites and alluvial diamond deposits; many of those deposits still await development. Probably many more deposits still need to be explored and discovered in a territory with a huge potential for diamond.

There is still a road to walk but the last ten years have seen an increasingly stable and growing economy in Angola, with successive elections being certified as free and fair by international organizations and a growing diversified media sector. The business environment has improved and a new mining code has been approved. Transport infrastructure is also being either rebuilt or erected from scratch.

Angola is a land of many opportunities for diamond investors. It has a special business environment and specific risks and challenges; we will guide you through them in this report. We will also discuss the current situation of the international diamond markets and its future trends and the impacts they may have on the Angolan industry. In the end, we hope this report will help you establish a successful venture in this land of promise.

The report has been authored by Luís Chambel, with major contributions by Luís Caetano and Manuel Reis. It is a joint effort by Sínese and eaglestone.

This report will be regularly updated, with major revisions expected annually.

This the is first of several reports on southern Africa the mineral industries.
