IIGJ Lab Introduces Paraiba Origin Certification Services
IIGJ Lab, an initiative by the GJEPC, has expanded its offerings by launching origin determination services for Paraiba tourmalines. This addition builds on its existing capabilities for emeralds, rubies, and sapphires (blue and pink), introduced in December 2025, in response to growing demand for traceability and scientific validation in coloured gemstones.
Paraiba tourmalines are known for their copper- and manganese-rich composition, displaying vibrant hues such as electric blue, neon blue, violet blue, bluish green to greenish blue, green, and yellowish green. Although the name originates from Paraiba, Brazil, it is now widely used for stones with similar characteristics regardless of their geographic source. Key commercial origins include Brazil, Mozambique, and Nigeria.
The lab will identify probable origin using advanced testing techniques, including chemical analysis, spectroscopy, and inclusion studies, strengthening its role as a standards-driven certification body aligned with industry needs.
In addition, IIGJ Lab has updated its naming guidelines. Only stones within the specified blue-to-green spectrum and coloured by copper and manganese will be classified as “Paraiba.” Stones in other shades, such as pink or purple, will not carry the Paraiba designation, though the presence of these elements will still be mentioned in report remarks.
