The truth about emeralds in Cartagena
Cartagena is not a mining city, but it is the main point of sale for Colombian emeralds to tourists. Here you can find everything from luxury jewelry stores in the Walled City to family workshops that have worked with gemologists for generations. The problem is that there are also street vendors offering synthetic stones at authentic prices. As of June 2026, demand for certified emeralds continues to grow, and knowing where to buy makes the difference between a safe investment and a scam.
Available options
Hidden family workshops in the Walled City
It is an urban myth that there are hidden family workshops in the Walled City that do not appear on Google Maps and operate only by referral. In reality, emerald workshops in Cartagena are usually registered and accessible through established jewelry stores or specialized tours, such as the emerald polishing workshop offered by local tour operators. To find reliable options, it is recommended to ask at recognized jewelry stores in the Historic Center, which can point you toward verified artisans.

Established jewelry stores in the Historic Center
Stores such as Museo de la Esmeralda (Calle 35 # 4-41) offer certified stones with a guarantee of authenticity. Their prices are higher than at workshops, but they include an invoice and an international certificate. They are ideal if you do not have time to look for hidden workshops. Other trusted jewelry stores include Casa La Esmeralda, which offers bracelets and 18k gold jewelry with excellent-quality Colombian emeralds.
Street vendors in Plaza de los Coches
Avoid them. They offer "BoyacĂĄ" emeralds at ridiculously low prices, but most are glass or synthetic. If you want to take the risk, bring a UV flashlight (I explain how to use it below).
Updated costs
The reference prices as of June 2026 are as follows, always subject to negotiation and carat weight:
- Untreated emeralds (medium-high quality grade): from $150,000 COP per carat in family workshops, up to $400,000 COP in established jewelry stores.
- Treated emeralds (cedar oil): from $80,000 COP per carat. They are cheaper, but they lose resale value.
- Mounted jewelry (rings, earrings, necklaces): from $500,000 COP up to $5,000,000 COP, depending on the gold and the stone.
- Gemological certificates: between $50,000 COP and $150,000 COP if you request them from a local laboratory such as GIA Colombia or IGL.
Important: family workshops usually accept cash or transfer, and give a discount if you pay in dollars. Jewelry stores accept credit cards without a surcharge.
Estimated times
If you go to the hidden workshops, the process can take between 1 and 3 hours, depending on whether you want to see the rough stone, choose the setting, and negotiate the price. In established jewelry stores, the purchase is faster (30 minutes), but if you request an additional certificate, it can take up to 24 hours. To export jewelry, the customs procedure at Rafael NĂșñez Airport takes about 20 minutes if you have your documentation ready.
Practical tips
How to distinguish an authentic Colombian emerald from a synthetic one
The quickest test is with an ultraviolet (UV) light flashlight. Natural Colombian emeralds do not fluoresce under UV, while synthetic ones or those from other origins usually emit a red or orange glow. You can also ask to see the stone with a 10x loupe: natural inclusions (such as small cracks or bubbles) are a sign of authenticity. If the stone is perfect and has no imperfections, it is probably synthetic or treated.
Ethical negotiation: base prices per carat
In workshops, the base price per carat is calculated according to color (intense green is more expensive), clarity (fewer inclusions, better), and weight. Do not negotiate below 60% of the initial price, because you would be insulting the artisan. A fair discount is 10% to 20% if you pay in cash. Avoid middleman commissions: if a taxi driver or tour guide takes you to a workshop, they are probably charged a 15% commission that you end up paying in the final price.
Documentation required to export jewelry
If you buy jewelry with emeralds and want to take it out of Colombia, you need:
- Purchase invoice with the seller's name, NIT, and description of the jewelry.
- Gemological certificate issued by a recognized laboratory (GIA, IGL, or the laboratory of the National Federation of Emeralds).
- Customs declaration at Rafael NĂșñez Airport. If the jewelry is worth more than USD 1,000, you must declare it on the departure form. Carry a copy of the invoice and the certificate.
- Secure shipping: if you prefer to send the jewelry by courier, use services such as DHL or FedEx with international insurance. Do not use traditional mail.
An interesting fact: Colombian emeralds do not pay export taxes if they are personal jewelry (fewer than 5 units). But if you carry more than 10 loose stones, they may ask you for a permit from the Ministry of Mines.
Frequently asked questions
Is it safe to buy emeralds on the street in Cartagena?
It is not recommended. Street vendors in Plaza de los Coches or Plaza de la Aduana usually offer synthetic or glass stones. If you insist, ask to see the stone with a UV flashlight and negotiate only if they offer you a certificate of authenticity from a local laboratory. Even then, the risk of scam is high.
How much does a gemological certificate cost in Cartagena?
At laboratories such as GIA Colombia or IGL, the certificate costs between $50,000 COP and $150,000 COP per stone, depending on weight. Some jewelry stores include it in the price of the jewelry. If you buy at a family workshop, you can ask them to take you to the laboratory to certify it before paying.
Can I export emeralds without any issues from the Cartagena airport?
Yes, as long as you have the purchase invoice and the gemological certificate. If the jewelry is worth less than USD 1,000, you do not need to declare anything. If it exceeds that value, fill out the customs form at the airport. Carry everything in your carry-on luggage to avoid losses. Never send emeralds in checked baggage without insurance.
Price Update and Emerald Market Situation in Cartagena
The emerald market in Cartagena has undergone notable changes in the last year. International demand for certified Colombian stones continues to rise, driven by buyers from North America, Europe, and Asia who come to the walled city in search of pieces with verifiable traceability. This increase in demand has pushed prices upward in formal channels, while the informal market continues to operate with opaque margins and a high percentage of synthetic or treated stones without declaration.
A key factor that is redefining the sector is the greater demand for certification on the part of buyers. More and more tourists arrive with prior knowledge about the characteristics of an authentic emerald and request documentation before closing any transaction. This has forced established jewelry stores in the Historic Center to standardize their processes and to work with recognized laboratories on a regular basis, not only when the client asks for it.
Another element that marks the current trend is the growing interest in jewelry set in contemporary designs, rather than the purchase of loose stones. Buyers seek ready-to-wear pieces, with certificate included and seller backing, which reduces the risk of fraud and simplifies the export procedure.
Factors that are moving prices in 2026
The final price of an emerald in Cartagena depends on a combination of variables that go beyond simple carat weight. The scarcity of high-quality untreated stones from the BoyacĂĄ mines has raised the value of pieces with intense green color and few inclusions. Added to this is the cost of gold, which directly impacts the price of mounted jewelry.
- Origin and treatment: untreated emeralds maintain a significant price premium compared to those treated with cedar oil or resins.
- Certification: a stone with a recognized laboratory certificate may cost more, but it offers a guarantee of authenticity and facilitates resale.
- Purchase channel: established jewelry stores in the Historic Center apply higher margins than verified workshops, but they include an invoice, warranty, and legal backing.
- Design and setting: pieces with designer design or artisanal setting in 18k gold increase their value compared to standard settings.
- Seasonality: the months of greatest tourist influx usually record higher demand and, with it, less willingness to negotiate discounts.
What sector experts say
Gemologists and traders consulted in the Historic Center agree on one diagnosis: the informed buyer is today the main filter against fraud. The recurring recommendation is never to buy without a certificate, to avoid offers that seem too good to be real, and to distrust any seller who pressures to close the transaction immediately.
Specialists also warn about a persistent phenomenon: the circulation of synthetic emeralds or those of origin other than Colombian presented as stones from BoyacĂĄ. These pieces are usually offered in crowded public spaces and at prices that bear no relation to the real market value. The unanimous recommendation is to limit purchases to verifiable establishments, with a physical address and provable track record.
Another piece of advice repeated among experts is to document every step of the transaction. Keeping the invoice, the certificate, and the seller's contact not only protects the buyer against any subsequent claim, but also facilitates export procedures and any future verification of the piece's value.
Current trends in emerald buying
The profile of the emerald buyer in Cartagena has changed compared to previous years. It is no longer only tourists looking for a souvenir: today buyers arrive with investment intent, collectors, and clients who value traceability and documentary backing above the lowest price.
This evolution has driven the formalization of the sector. Jewelry stores in the Historic Center have expanded their services to include gemological advisory, certification at the time of purchase, and support with exit procedures from the country. Some establishments even offer the possibility of processing the certificate before the client pays, which reduces uncertainty and reinforces confidence in the transaction.
At the same time, interest grows in pieces with history and local design, made by goldsmiths from the region. This type of jewelry combines the intrinsic value of the emerald with an artisanal component that makes them unique and difficult to replicate, an attribute increasingly appreciated among buyers looking for something more than a stone.
Transparency is thus consolidated as the main asset of the formal market in Cartagena. Whoever buys in a verified establishment, with an invoice and certificate, not only acquires an emerald: they acquire certainty of its origin, its value, and its legality, something that no street vendor can guarantee.
