Ethiopian vs Brazilian Paraíba Tourmaline
Brazil is where the Paraíba name began and remains the market’s benchmark. Comparisons with Ethiopia must account for the large gap in documentation between the two sources.

How do Ethiopian and Brazilian Paraíba compare?
Brazilian material is historically documented, very limited in supply and often associated with the most saturated neon colours. Ethiopian material is recent, less documented and must be verified stone by stone.
| Attribute | Ethiopia | Mozambique | Brazil |
|---|---|---|---|
| Geographic origin | East Africa. Specific localities to be documented with verified sources. | East Africa; deposits most often cited in Nampula Province (Alto Ligonha pegmatite district). | North-eastern Brazil; the original Paraíba deposits and later finds in Rio Grande do Norte. |
| Typical colour range | Blue, green and blue-green tourmaline reported in the trade; systematic colour documentation in progress. | Blue, greenish blue, green, violet to purple; frequently heated to modify colour. | Neon blue, greenish blue, green and violet; the reference point for “neon” saturation. |
| Copper-bearing material | Must be confirmed stone by stone through chemical analysis. Colour alone is not evidence. | Copper-bearing material documented in published literature. | Copper-bearing material documented since the original discovery. |
| Market history | Comparatively recent and less documented; this site aims to build a verified record. | Entered the market in the 2000s and now supplies much of the Cu-bearing tourmaline trade. | Introduced to the international market around 1989; the origin of the trade name. |
| Rarity | Not yet quantified. Production volumes are not reliably published. | Rare in fine qualities; larger clean stones occur more often than from Brazil. | Very limited historic production; fine large stones are exceptionally rare. |
| Origin determination | Depends on each laboratory’s reference collection for Ethiopian material, which may be limited. | Laboratories may offer an origin opinion based on trace-element chemistry and reference data. | Laboratories may offer an origin opinion; Brazilian origin often carries a market premium. |
