Goiás, Brazil

Brazilian emeralds.
Campos Verdes roots.

A discovery during roadwork in 1981 helped shape an emerald-mining town. Its history is the starting point for understanding the material.

Campos Verdes, Goiás

A town shaped by emeralds.

Campos Verdes grew around an emerald discovery in Goiás. Its story connects a mining community with the wider worlds of gem research, cutting and trade.

  1. 1981

    An unexpected discovery

    A road-grader operator uncovered green stones near Fazenda São João. Initially thought to be tourmalines, they were identified as emeralds. News travelled, drawing miners from Bahia, Maranhão, Minas Gerais and beyond.

  2. 1983

    A community, not just a mine

    Medical care, shops and a primary school followed the influx of miners. The settlement was known as Garimpo; people arriving from Bahia also brought experience in buying and selling emeralds.

  3. 1987

    A town takes shape

    Previously part of Santa Terezinha de Goiás, the settlement became the municipality of Campos Verdes on 30 December 1987. Its name paid tribute to the emerald green associated with the locality.

Inside the stone

A reference point for gemologists.

A GIA field expedition collected emerald samples from Campos Verdes for its coloured-stone reference collection. Presented at Converge 2025, the research highlights a revealing detail: the stones’ chemistry and inclusions can resemble emeralds from Pakistan, Afghanistan and Colombia.

That overlap is why a stone’s appearance alone cannot settle its geographical origin. Reference samples help gemologists compare the evidence inside a gem, rather than relying on a place name or a particular shade of green.

Beyond the mine

Where material meets craftsmanship.

The town’s International Emerald Fair brings the wider trade into the story. Its tenth edition, advertised for 19–21 September 2025, offered visitors the chance to buy emeralds and jewellery, explore the process from extraction to finished pieces and visit mining areas.

It offers another way to understand Campos Verdes: not only as a source of rough stones, but as a meeting point for the skills and conversations that follow a discovery.

Frequently asked questions.

What should I consider before acquiring?

A qualifying acquisition requires eligibility checks, independent advice and an understanding of illiquid assets. It is not suitable for guaranteed-income or short-term liquidity needs.

What happens to membership if I later sell my lot?

The continuation and renewal terms after a sale still need to be finalised. Ask the team to confirm these in your private membership documents before joining.

Can I apply on behalf of an organisation?

Yes. Authority and beneficial ownership are verified during private onboarding.

What if I decide not to acquire?

You can enquire and review the private information without committing. If you do not complete a qualifying acquisition, membership does not activate. Any accepted transaction commitments are governed by the signed documents.

What can I do at campaign review?

Consider an offer, extend the mandate, hold the lot, propose another approved sales channel or request lawful delivery where permitted. Each route remains subject to the agreement, applicable costs and compliance.

What are the main risks?

Rough emeralds may take a long time to sell and a sale may not occur. A member may lose part or all of the allocated capital and associated costs. There is no transparent exchange price. Colour, inclusions, treatment, origin, size, condition and cutting yield can materially affect value. Documents, suppliers, service providers, custodians, insurers and buyers may fail, default or become subject to dispute. Loss, damage, substitution, record error, transport interruption and inadequate insurance are possible despite controls. Foreign-exchange movements, duties, taxes, professional fees, custody and logistics can reduce or eliminate any profit.

What legal and regulatory conditions apply?

Club information is preliminary, not a public offer, prospectus, recommendation, deposit product, guarantee, fiduciary advice or personal investment advice. Participation depends on eligibility, due diligence, available lots, final documents and applicable law. Cross-border rules, marketing restrictions, export requirements and member eligibility may change or restrict a transaction. Operator identity, providers, commercial terms and legal structure remain subject to approval; this website creates no obligation to admit a member or complete a transaction. Obtain independent legal, tax, regulatory, financial and gemstone advice. No funds should be accepted before the required approvals or released before title, source, quality, insurance, custody, logistics, banking and counterparty checks are complete. Imagery is illustrative, not proof of origin, title, quality, treatment, availability or value. Final contracts govern; the full agreement is provided privately after the team qualifies an enquiry.
