Introduction
Proud of our legacy to the North
Dominion Diamond Corporation
Dominion Diamond Corporation is the world’s third largest
producer of rough diamonds by value and is listed on
both the Toronto and New York stock exchanges. Both of
its production assets are located in the low political risk
environment of the Northwest Territories in Canada where
the company also has its head office.
Dominion operates the Ekati Diamond Mine, through
its 88.9 per cent ownership, as well as a 65.3 per cent
ownership in the surrounding areas containing additional
reserves and resources, and also owns 40 per cent of the
Diavik Diamond Mine. Between the two mining operations,
diamonds are currently produced from a number of separate
kimberlite pipes, providing a diversity of diamond supply
as well as reduced operational risk. It supplies premium
rough diamond assortments to the global market through its
sorting and selling operations in Canada, Belgium, and India.
The company maximizes the sales value of its rough stones
from the Ekati and Diavik mines, and maintains a preferred
position as a supplier of rough diamonds to the world’s
diamond manufacturers (cutters and polishers) by dealing
directly with them and tailoring rough diamond parcels to
the client’s particular needs.
Rio Tinto Diamonds
Through its 60 per cent of the Diavik mine and 100 per cent
of the Argyle mine, Rio Tinto Diamonds is one of the world’s
major diamond producers. Rio Tinto Diamonds’ share of the
production from these mines are sorted and prepared for sale
at its sales and marketing headquarters in Antwerp, Belgium.
Rio Tinto Diamonds’ sales and marketing group aims to
differentiate itself by:
• Providing the right customer with the right assortment of
diamonds;
• Tailoring its approach to serve each customer;
• Creating long-term, mutually beneficial business
relationships; and
• Retaining the flexibility to respond to market
opportunities.
It maintains an extensive industry intelligence network
and a high level of customer and product support, and also
believes in supporting consumer confidence in its diamonds
and plays an active role in addressing key industry issues
around product integrity and sustainable development.
Rio Tinto Diamonds is a founding member of the Responsible
Jewellery Council. Established in 2005, the council is a notfor-profit
industry organization with a mandate to promote
responsible, ethical, social, and environmental practices
throughout the diamond and gold jewellery supply chain
from mine to retail.
Additionally, Rio Tinto Diamonds has taken an active
leadership role in the World Diamond Council, which
represents the diamond industry in the Kimberley process.

More recently, Rio Tinto Diamonds has partnered with the
Diamond Empowerment Fund – an international not-forprofit
organization supporting education initiatives in
diamond producing countries – on a number of programs
aimed at raising awareness of the positive impact diamonds
have around the world in the communities in which they are
mined.
