Opal mining in Piauí operates under strict environmental regulations. The work is predominantly carried out by individuals and small local cooperatives using low-impact methods, free from harmful chemicals or destructive heavy machinery.

While the mining process does shift the soil, the land remains uncontaminated and naturally regenerates over time, allowing birds and small wildlife to quickly return to their habitats. Compared to large-scale diamond or precious stone mining, sourcing our opals is significantly more eco-friendly and ethical.

When you choose a gemstone from BrazilOpals, you are supporting responsible sourcing and ensuring a minimal environmental footprint.

Our gemstones are extracted directly by our own team in Piauí, Brazil. We are not resellers; as the direct miners, we ensure ethical practices and unmatched quality control at every step of the process.

By purchasing from us, you get your gemstones straight from the source. Every piece is thoroughly evaluated and arrives with a certificate of authenticity, guaranteeing its natural origin and exceptional quality.

Our online store is designed to give you the best experience possible. Our system is fully secure and seamlessly integrated with major payment gateways and shipping options, ensuring your gemstone or jewelry reaches you quickly and safely, anywhere in the world.

The opals available on our website are exclusively selected, cut, and polished by our team. We do not sell stones processed by unknown middlemen.

Because of this, we proudly issue a certificate of authenticity guaranteeing the Piauí origin, classification, and quality of your gemstone.

• For every opal purchased from us priced over $150, a printed certificate will be included with your order free of charge.
• For opals priced under $150, we can provide a printed certificate for a small processing fee of $8. Simply include this request in the order notes at checkout, and we will take care of it.
