Introduction
Donge Zuanbao Diamond Co. is a multinational corporation engaged primarily in the extraction, processing, and retail of high‑quality diamonds and related luxury jewelry. Founded in the early 21st century in Shenzhen, China, the company has expanded operations to several continents, establishing mining concessions in Africa, Australia, and Canada, and operating retail outlets in major metropolitan markets worldwide. The firm has positioned itself as a vertically integrated player in the diamond industry, controlling the value chain from mine to finished product. This article provides a comprehensive overview of the company’s history, corporate structure, operational activities, financial performance, and strategic initiatives.
History and Background
Founding and Early Years
The origins of Donge Zuanbao Diamond Co. can be traced to 2004, when entrepreneur Chen Li, formerly a senior executive at a leading Chinese mining conglomerate, identified a gap in the domestic diamond market. He envisioned a company that would combine modern mining technology with sophisticated design capabilities to produce premium diamond jewelry for both domestic and international consumers. In 2005, Chen incorporated Donge Zuanbao Diamond Co. as a private limited company in Shenzhen, securing initial capital from a consortium of domestic investors.
Expansion into International Markets
By 2010, the company had opened its first overseas mining concession in Botswana, one of Africa’s most prolific diamond-producing regions. The acquisition was financed through a combination of equity injections and long‑term credit facilities from Chinese banks. The Botswana operation, known as Zuanbao Botswana Ltd., focused on open‑pit mining and initial rough diamond processing. In the same year, the firm established a design studio in Hong Kong, leveraging the city’s status as a global jewelry hub to develop proprietary collections.
Public Listing and Global Footprint
In 2014, Donge Zuanbao Diamond Co. completed an initial public offering on the Shenzhen Stock Exchange, providing liquidity for early investors and raising capital for further expansion. The listing was followed by a strategic partnership with a South African mining group, granting the company access to the vast resources of the Karoo Basin. Subsequent acquisitions in Australia (2017) and Canada (2019) diversified the firm’s resource base and reinforced its global footprint. As of 2026, the company operates mining facilities in four continents and maintains retail presence in over 30 countries.

Operations and Mining Activities
Mining Operations
Donge Zuanbao’s mining operations are organized around three core modalities: open‑pit, underground, and alluvial mining. Each modality is tailored to the geological characteristics of the concession:
- Open‑pit mining in Botswana and Australia targets large, low‑grade kimberlite pipes, using high‑capacity drills and conveyor systems.
- Underground mining in South Africa’s Gaborone Basin focuses on high‑grade, pegmatitic diamonds, employing advanced tunnel ventilation and ore sorting technology.
- Alluvial mining in Canadian riverbeds captures secondary deposits, utilizing hydraulic sluicing and mechanical sorting.
Safety standards at Donge Zuanbao mining sites are governed by international regulations, including ISO 45001. The company maintains an on‑site medical center and a dedicated emergency response team at each facility.
Processing and Grading
Raw diamonds are transported to the company’s processing plants located in Shenzhen and Johannesburg. The processing pipeline comprises the following stages:
- Crushing and separation of kimberlite from waste rock.
- Gravity concentration and magnetic separation to isolate diamond‑bearing material.
- Advanced optical sorting, employing machine learning algorithms to detect inclusions and grade clarity.
- Cutting and polishing, performed by a combination of skilled artisans and automated laser cutters.
The grading system follows the Gemological Institute of America (GIA) standards, ensuring that each diamond’s carat weight, cut, color, and clarity are meticulously documented. Graded diamonds are then packaged for design or direct retail sale.
