Yes. The online registration is part of standard due diligence procedures, which are legally required by Angolan regulations and international business practices governing the diamond trade.

No. Once you are registered, you will only be able to participate in competitive sales organised by SODIAM on behalf of Angolan producers.

Supply contracts are directly negotiated with and allocated by the producers, while SODIAM acts as the single channel to the market.

It is SODIAM’s corporate policy not to work with brokers or intermediaries.

Applications submitted via third parties shall not be considered and diamond companies that are approached by individuals or consulting firms claiming to be able to build relationships with SODIAM should disregard these offers and consider them as fraudulent.

Your application to SODIAM may be denied for the following reasons:

- You are not a member of any rough diamond trading bourse and actually do not belong to the rough diamond trading community;

- You have not met the minimum annual rough purchase threshold of US2m. for Angolan entities or US10m. for foreign entities;

- You have submitted false or inaccurate information in your application;

- You do not comply with our Terms and Conditions.

Only up to two company representatives may be granted access to the online platform and be able to submit bids. Those representatives must therefore be individuals who are legally authorised to take a financial commitment on behalf of the company.

Primary and secondary representatives should be registered with a different e-mail address.

Absolutely. Nevertheless, you should make sure that their name and date of birth are correctly encoded since a proof of identity will be required before being allowed to access the viewing room.

Please also note that you are legally responsible for any valuator you may bring to the inspection.

This means that the encoded shareholding percentage is either below 80%, or exceeding 100%.

The stakes owned by individuals and legal entities add up.

The Unique Identification Code (UIC) is a functionality offered to registered customers to enable them to transfer invoices from one registered company to another within the same shareholding structure or with the same ultimate beneficiaries.

The UIC is only automatically generated once you have been successfully registered and can be found on the top of the section 'Company details'. This means that if you are registering with us for the first time, you do not have a UIC yet.

Concretely, it works as follows: If you are registering Company B and have Company A already registered with us, you may then link both entities with the UIC provided that both companies are within the same shareholding structure or have the same ultimate beneficiaries.

Once the link is validated, if you then hypothetically win a lot through Company B, the UIC will allow you to pay from Company A, while maintaining the full traceability on the origin of the funds.

Please specify the contact person within your organisation responsible for proceeding payments. This contact person should not be your bank officer, nor your external accounting/auditing firm.

Please encode the bank account number, which is indicated on the corresponding bank reference letter.

No. Please only select the areas for which you have developed a particular know how, enjoy an established distribution network and have regular and stable demand.

No, unless the information provided is voluntarily false.

Nevertheless, please note that if you are not already a member of a rough diamond trading bourse or of a reputable trade organisation, your application will most likely be rejected.

No. If you do not have a supply contract of agreed committed purchases with any of those miners, you should tick ’none’.

A company organisational chart is a diagram that shows the structure of your company and the relationships and relative ranks of its parts.

If your company is part of a larger group, the chart should show the shareholder structure with percentages of holdings, including all subsidiary companies and beneficiaries.

If your company is a standalone entity, the chart should show the internal company structure with shareholding percentages and the different positions of the key individuals.

For examples of organisational charts, please search on the Internet through your web browser for "shareholding structure chart” or “organisational chart”.

You should first compress the file so that it does not exceed the maximum size limit.

Your computer should have an already built-in file compression application.

If not, you may use online applications by searching on the Internet through your web browser for “online file compression”. Small PDF ( is for instance a popular online tool.

- Stay in areas that have effective air conditioning;

- Apply insect repellent on your skin;

- Wear loose-fitting trousers rather than shorts and shirts with long sleeves rather than polos.

Bids are submitted through a secure and encrypted connection, which prevents SODIAM and the producer from being able to see the value of any bid before the closing of the submission period.

The bidding currency / value is in United States dollars ($) and a bid must be entered in respect of individual lots and not in respect of a combination or aggregate number of lots.

Bids can be entered in value per carat amount ($/ct) or in total value per lot ($); whichever field is entered; the other field is automatically populated.

Bids can be submitted, modified, or withdrawn at any time up until the end of the bid submission period.

Once the submission period has ended, any bid is final and shall stand as an offer to buy the lot in respect of which the bid is made.

You shall not receive a notification e-mail for the bids submitted, nor at the closure of the submission period.

In order to be protected from inadvertently over-stretching your budget and be able to bid with full confidence, you may predefine a spending limit, i.e. the maximum amount you would be prepared to buy at the sale.

In case you have submitted several successful bids and the total amount of the lots won exceeds your spending limit, SODIAM shall then reduce your total purchase to an amount that is below your pre-defined spending limit.

To do so, SODIAM shall allocate to you one or several lots for which you have submitted the highest bid by the highest margins relative to the second highest bidder or otherwise, so that the total value won does not exceed the pre-defined spending limit.

The minimum value of the spending limit shall not be lower than the value of the highest individual bid submitted. This means that if you place an individual bid, which is higher than your previously defined spending limit, the spending limit will then be automatically increased in order to match that individual bid.

You may activate, deactivate, or modify your spending limit at any time prior to the end of the bid submission period.

After the closure of the bid submission period, SODIAM opens the submitted bids in the presence of representatives from the producer, ENDIAMA, and the Ministry of Mineral Resources and Petroleum.

SODIAM may call any bidder and record an oral confirmation of either the total submitted value for all lots, or of the total submitted value for each bid placed. This second factor confirmation of the bids submitted through the online platform is a random verification procedure performed for internal auditing and security purposes.

The highest submitted bids on each offered lot are then considered and subsequently accepted or rejected by the producer.

Where two or more bidders have submitted the same winning price, SODIAM shall contact by phone each customer informing them that they are joint-highest bidder with one or more parties and offer them the opportunity to review their bidding price. Should the joint-highest bidders be unreachable or decide to keep the same bid within twenty minutes after having been notified, SODIAM shall allocate the lot for which equal bids have been submitted to the joint-highest bidder that has won the highest value during that particular sale. If none of the joint-highest bidders have submitted a winning bid on another lot, SODIAM shall then decide by drawing of lots, which of the bidders shall be the winner.

As soon as practically possible, but nevertheless, within one working day after the closure, SODIAM shall notify successful bidders by phone and/or e-mail.

As far as public disclosure of the results is concerned, it is ultimately up to the producer to decide to share the selling prices or not. SODIAM is therefore entitled, but not obliged, to publish the results of the sale.

If it does so, in order to avoid arguable price discovery behaviours among bidders, the final selling price for each lot is shared online via the bidding platform only and only against submitted bids of reasonably-acceptable value. Concretely, this means that bidders will only be able to see the final selling price of the lots for which they have submitted a bid, and only provided that the submitted bid is higher than 75% of the selling price.

Winning customers may only pay through a different company if that legal entity is already registered with us and already linked to the invoiced company via a Unique Identification Code (UIC).

In such case, successful bidders may also split payments between the different registered entities.

Invoices must be paid within five working days after receipt.
