Origin of Zambian Emerald

Geographic sources and historical origins

Kagem mine

Grizzly Mine

Mine Chantete

The émeraudes de zambie were first discovered in the early 20th century, with the start of major mining operations in the 1970s. Since then, these captivating gemstones have gained recognition for their exceptional quality and distinct coloring.

The main source of Zambian emeralds is the Kafubu Emerald Belt, located in the Ndola Rural Emerald Restricted Area in the Copperbelt Province of Zambia. This area spans over 200 square kilometers and is home to several major mines, including the Kagem Emerald Mine, the largest emerald mine in the world, as well as the Grizzly and Chantete mines, among others.

The unique geological conditions in the Kafubu Emerald Belt contribute to the formation of these extraordinary stones. Zambian emeralds are formed by the interaction of beryl, a mineral found in the earth's crust, with chromium and vanadium. This interaction results in the formation of the mesmerizing green shade characteristic of emeralds.

In addition to the Copperbelt Province, smaller deposits of Zambian emeralds have been discovered in other parts of the country. However, the Kafubu Emerald Belt remains the most significant and consistent source of these gems.

The value and quality of a Zambian Emerald

How to know the value of a Zambian Emerald ?

The Emeralds from Zambia are highly valued for their distinct color, clarity and rarity, making them a sought-after choice among gem enthusiasts and collectors. The most crucial aspect of the value of a Zambian emerald is its color. The finest stones feature a vibrant, evenly saturated green shade with a slight bluish undertone. Stones with exceptional color command a higher price. Zambian emeralds are generally cleaner and less included than their counterparts colombiennes. Those with fewer inclusions and higher transparency sell at a premium price.

‍

‍ Large, high-quality Zambian emeralds are rarer, and their value increases exponentially with size. As carat weight increases, so does the price per carat. A well-cut Zambian emerald maximizes its color and luster, enhancing the overall beauty and value of the gem. Higher quality cut stones have higher prices.‍

‍

He it is essential to note that the Zambian emerald market is relatively more affordable compared to Colombian emeralds, providing an excellent opportunity to own a stunning gemstone at a competitive price. However, due to increasing demand and limited supply, the value of Zambian emeralds is expected to increase over time, making them a wise investment.

Treatment and improvement of Zambian Emerald

What are these treatments ?

It is common for these emeralds, including émeraudes de Colombie, are processed.

The most common treatment is oil treatment which improves their clarity and minimizes the appearance of inclusions called "gardens". The treatment involves filling the natural fractures and inclusions in the stone with natural oil. This treatment is widely accepted in the gemological industry and is considered standard practice.

Untreated or lightly treated Zambian emeralds of exceptional quality are rare.

Our Sourcing of Precious Stones

At Bonnot Paris, we are committed to providing the best precious stones through rigorous and ethical sourcing.

We've developed three main sourcing methods to ensure the quality and traceability of our gems: directly from mines, through brokers, and from renowned cutting centers. Discover our methods in detail below.

LEVEL 1

Directly at the mine

We favor direct partnerships with mines, which allows us to obtain rough gemstones directly from the source.

Our partnerships span the globe, including Africa (Namibia, Mozambique, Tanzania, Kenya), Vietnam, and Sri Lanka. We carefully select gemstones based on their quality and then have them cut by our workshops in France and Bangkok, ensuring complete control over the transformation process.

LEVEL 2

From local Brokers

Our collaborations with international brokers allow us to acquire precious stones over a wide geographical area.

These brokers, based in Africa, Brazil, Colombia, and Vietnam, travel across vast territories to source gemstones that meet our strict criteria of quality, traceability, and price. The purchased rough stones are then cut in our specialized workshops in France and Bangkok.

LEVEL 3

From the main pruning centers

We have strategically located offices in Jaipur, Bangkok and Beruwala (Sri Lanka).

These centers allow us to purchase pre-cut gemstones, such as Zambian emeralds in Jaipur or sapphires and other various gemstones in Sri Lanka and Bangkok. Thanks to these offices, we can precisely meet the specific demands of our customers by offering a wide range of high-quality stones.

LEVEL 4 - NOT APPLIED AT BONNOT PARIS
