800690849 GCALSarine Technologies has opened a new GCAL by Sarine Jewellery Certification and Quality Assurance Lab at SEEPZ, Mumbai, strengthening its presence in India’s jewellery manufacturing and export sector.

The Mumbai laboratory complements GCAL by Sarine’s existing facilities in Surat and New York. Surat remains positioned within India’s diamond manufacturing ecosystem, while the SEEPZ facility focuses on jewellery manufacturing and exports. The network is designed to connect India’s key manufacturing centres with the US jewellery market through a more efficient certification infrastructure.

The new lab expands GCAL by Sarine’s Indian offering from diamond grading into jewellery certification and quality assurance. Its grading and certification services are supported by GCAL’s consumer guarantee, with the company highlighting grading integrity, consistency and consumer confidence as key priorities.

Tzafrir Engelhard, CEO, Sarine, said, “Our new SEEPZ lab enables us to serve customers closer to the point of jewellery production while leveraging the strength and reputation of the GCAL by Sarine brand. We are particularly pleased to have completed the establishment of the new lab ahead of this year’s peak season, allowing us to support our customers at an important time for the industry.”
