Origin of the Colombian Emerald

Geographic sources and historical origins

Muzo Mine

Chivor Mine

Coscuez mine

The émeraudes colombiennes are mainly extracted from andes mountains in Colombia, where they are found in sedimentary rocks more than 65 million years old. Emerald deposits are located in areas with specific geological conditions favorable to the formation of these precious stones. Emerald deposits are estimated to have formed during the Cretaceous period, when the Andes mountains were created due to the collision of tectonic plates.

The emerald deposits in Colombia are found in black shale rocks containing high levels of organic matter. For millions of years, shale was subjected to intense pressure and heat, causing organic matter to break down and form hydrothermal solutions. These solutions circulated through the rocks and deposited minerals such as chromium and vanadium, responsible for the bright green color of Colombian emeralds.

Emerald deposits in Colombia are found in several regions of the country, including muzo mine, Chivor mine and Coscuez mine. These mines are renowned for producing some of the highest quality emeralds in the world, with bright green colors and exceptional clarity.

The value and quality of a Colombian Emerald

How to know the value of a Colombian emerald ?

The émeraudes colombiennes have been prized for centuries for their unique origins and exceptional beauty. They have been used in jewelry by many historical figures, including Cleopatra and the Incas. Today, Colombian emeralds remain one of the most sought-after gemstones in the world, valued for their rarity, beauty and unique geological origins. The color of a Colombian emerald is one of its most important and distinctive characteristics.

‍
The most prized color for Colombian emeralds is a pure, rich green with a slight blue or blue-green tint. This color is often called "emerald green" and is the classic and traditional color associated with emeralds. In addition to the classic emerald green color, Colombian emeralds can also feature a range of other shades and tones. Some stones may have a yellowish green or bluish green tint, while others may be paler or lighter. These color variations can be attributed to various factors, such as the specific mineral composition of the stone, its origin, and any treatment or enhancement it may have undergone. When choosing a Colombian emerald, it is important to choose a stone with a color that you like and that matches your preferences. A high quality Colombian emerald should exhibit a rich, intense green color with high saturation and an even tone throughout the stone.

Treatment and improvement of Colombian Emerald

What are these treatments ?

It is common for Colombian emeralds, including émeraudes de Zambie, are treated with oil to improve their clarity and minimize 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 Colombian emeralds of exceptional quality are very rare and highly sought after. It is important to note that this treatment improves the appearance and value of the stone if done correctly and disclosed transparently.

All our emeralds come with a certificate of authenticity.

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.

More competitive prices

These three levels of sourcing allow us to offer you the best precious stones at the best price, while guaranteeing their origin and exceptional quality.

We are committed to maintaining these standards to continue to satisfy our most demanding customers.

LEVEL 4 - NOT APPLIED AT BONNOT PARIS

From Merchants Resellers

The vast majority of traditional jewelers use dealers in their country to buy their stones.

This results in a limited choice of products and, above all, prices that are far removed from market prices.

LEVEL 5 - NOT APPLIED AT BONNOT PARIS

At the jeweler

Once again, the majority of jewelers tend to favor the sale of their own stones to the detriment of customer desires.

By offering only a limited selection, the jeweler inevitably influences the choice. At Bonnot Paris, it's the customer who chooses, and we source the ideal stone for their needs.

Certification and Ethics: OurCommitments

Certification and ethics are essential pillars of Maison Bonnot Paris. Each stone we offer is certified by renowned independent laboratories, such as GIA, AIGS, ICA, LFG, and SSEF.

This guarantees the authenticity and quality of our gems. In addition, we pride ourselves on knowing the origin of the majority of the stones we offer.

Many come from brokers located in extraction areas we know well, ensuring impeccable traceability and ethics.

Although ethics is at the heart of our commitment, we recognize that much remains to be done in this area.

We are committed to continuing our efforts to ensure responsible and ethical sourcing of every stone.
