The Gübelin Gem Lab has introduced the Emerald Paternity Test, a new service that uses DNA-based nanoparticles to offer proof of emerald provenance.
This is the first time nanotechnology—which deals with dimensions of less than 100 nanometers, and is invisible even to microscopes—has been used in this context.
Gemfields, owner of Kagem, the world’s largest emerald mine, has joined the project as a test partner.
The Emerald Paternity Test is the first in a series of services Gübelin will be offering that are meant to increase transparency in the gemstone market, under the Provenance Proof label.
