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 will find everything from luxury jewelry stores in the Centro Amurallado 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. In June 2026, the 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
There are at least three workshops that do not appear on Google Maps and are only managed by referral. They are located on streets like Calle del Porvenir or Calle de la Moneda, on second floors of colonial houses with no sign. To contact them, it is best to ask at trusted jewelry stores like Joyas Mónaco (Calle San Juan de Dios) or Esmeraldas Colombianas (Bocagrande). They will pass you the contact for the workshops if they see you are a serious buyer.

Established jewelry stores in the Historic Center
Stores like Museo de la Esmeralda (Calle 35 # 4-41) or Green Fire (Plaza de San Diego) offer certified stones with an authenticity guarantee. Their prices are higher than in the workshops, but they include an invoice and an international certificate. They are ideal if you don't have time to look for hidden workshops.
Street vendors at Plaza de los Coches
Avoid them. They offer "from Boyacá" emeralds at ridiculously low prices, but most are glass or synthetics. If you want to take the risk, bring a UV flashlight (I explain how to use it below).
Updated costs
The reference prices in 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 more economical, but lose resale value.
- Mounted jewelry (rings, earrings, necklaces): from $500,000 COP 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 like GIA Colombia or IGL.
Important: family workshops usually accept cash or bank transfer, and give a discount if you pay in dollars. Jewelry stores accept credit cards without 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 Núñez Airport takes about 20 minutes if you have the documentation ready.
Practical tips
How to distinguish an authentic Colombian emerald from a synthetic one
The quickest test is with an ultraviolet (UV) 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 (like 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 based on color (intense green is more expensive), clarity (fewer inclusions, better), and weight. Do not negotiate below 60% of the initial price, as you would be insulting the artisan. A fair discount is 10% to 20% if you pay in cash. Avoid intermediary commissions: if a taxi driver or tour guide takes you to a workshop, they are likely charging a 15% commission that you end up paying in the final price.
Necessary documentation to export jewelry
If you buy jewelry with emeralds and want to take them 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 Emerald Federation).
- Customs declaration at Rafael Núñez Airport. If the jewelry is worth more than 1,000 USD, you must declare it on the departure form. Bring a copy of the invoice and the certificate.
- Secure shipping: if you prefer to send the jewelry by courier, use services like DHL or FedEx with international insurance. Do not use regular mail.
A curious fact: Colombian emeralds are not subject to export taxes if they are personal jewelry (less than 5 units). But if you carry more than 10 loose stones, you may be asked 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 at 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 an authenticity certificate from a local laboratory. Even so, the risk of being scammed is high.
How much does a gemological certificate cost in Cartagena?
In laboratories like GIA Colombia or IGL, the certificate costs between $50,000 COP and $150,000 COP per stone, depending on the weight. Some jewelry stores include it in the price of the jewelry. If you buy from a family workshop, you can ask them to take you to the laboratory to certify it before paying.
Can I export emeralds without problems from Cartagena airport?
Yes, as long as you have the purchase invoice and the gemological certificate. If the jewelry is worth less than 1,000 USD, 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 loss. Never send emeralds in checked baggage without insurance.
