Zambian Emeralds Co.
Ethical Excellence, Unrivalled Quality, Timeless Value
Zambian Emeralds Co. is an internationally renowned source of rare, premium‑grade emeralds. Every stone in our collection originates from responsibly managed mines owned by Gemfields, a publicly listed leader on both the London Stock Exchange and the JSE. Gemfields adheres to very high environmental, social and governance standards, ensuring that each emerald is extracted with minimal ecological impact and full respect for local communities.
Once the rough Emeralds are obtained, it is entrusted to master cutters whose decades‑long expertise transforms each crystal into a flawless, premium‑quality gemstone. Meticulous attention to proportion, symmetry and brilliance yields an emerald that shines with unrivalled brightness and colour consistency.
Every finished stone undergoes an independent assessment by ISO‑9001:2008 accredited gemological laboratories located in Antwerp, London, Ramat Gan and Zürich. These independent third‑party experts verify authenticity, assign colour, clarity and cut grades, and provide a professional appraisal of market value. Their findings are recorded in a formal Gemological Certificate, and the stone is sealed with a tamper‑proof security tag signed by the laboratory director before returning to us.
Only emeralds that achieve the highest possible grades are offered to our discerning clientele. Whether you intend to add a singular masterpiece to a private collection, incorporate it into a bespoke piece of fine jewellery, or hold it as a strategic store‑of‑value within a family office or hedge‑fund portfolio, you can be confident that you are receiving a stone of exceptional provenance and verified excellence.
Why Zambian Emeralds Stand Out:
Distinct Colour Profile – Zambian emeralds are celebrated for a vivid, medium‑green hue with a subtle cool undertone, offering a fresh alternative to the classic Colombian palette while retaining comparable depth and saturation.
Rarity and Consistency – The geological conditions in Zambia produce relatively few large, high‑clarity stones, making each 1‑carat (or larger) emerald a truly scarce asset.
Ethical Assurance – Gemfields’ commitment to responsible mining means every stone is conflict‑free, traceable, and sourced under strict labour‑rights and environmental safeguards.
Investment‑Grade Attributes:
Emeralds have historically demonstrated resilience as a tangible asset class. Their limited supply, combined with growing demand from luxury markets and collectors, often translates into price appreciation over time. Our certificates provide the transparency required for institutional investors, allowing seamless inclusion of emeralds in diversified portfolios, estate planning strategies, or wealth‑preservation schemes.
Bespoke Services for Discerning Buyers:
Custom Design Collaboration – Partner with our network of award‑winning jewellery designers to create one‑of‑a‑kind settings that highlight the stone’s unique characteristics.
Secure Shipping & Insurance – All certified emeralds are dispatched using expedited Express delivery in climate‑controlled packaging, fully insured against loss or damage during transit.
Patrons Care Programme – We offer complimentary cleaning, polishing and re‑certification (upon request) to preserve the stone’s brilliance and documented value throughout its ownership life.
Comprehensive Return Policy - We offer an extended 45 days return policy. The item can be sent back to us, and full refund will be sent upon receipt of the returned item in its original unopened gemological seal.
GemVal Evaluation - In order to allow our patrons to keep track of the market value of their emerald, we document our emeralds in the online value database GemVal, one of the gems-market's utmost reliable sources for precious gemstones market prices. Updated each month, our patrons can access their emerald value entry's information, to review its current value under the up-to-date market conditions.
Sourcing Emeralds from Other Terroirs - Some of our Patrons are looking to extend their collection with Emeralds from other terroirs. We are able to source decades-old Emeralds from other locations, like Colombian Emeralds from Muzo or Coscuez, in collections owned by private individuals. We can locate the perfect vintage Emerald to meet your demands, and try to facilitate a transfer of Emerald into your collection, on behalf of the owner.
Professional Publications - We offer professional publications for market executives. Beginning in September 2025, we suggest some of our publications for open-access to the general public through our "Publications" section in our website.
Highest Information Security Practices - We regard information security in the utmost meticulous standards, adhering to the same practices taken by the world's renowned Swiss banks. Our communication servers are located in a top security facility in Switzerland, and implement layers of military grade Elliptic Curve Cryptography encryption for storage and secured S/MIME communications (Secure/Multipurpose Internet Mail Extensions).
