Where does your Tiffany diamond come from? Now you can find out

In an exclusive interview, Alessandro Bogliolo, Tiffany & Co.’s CEO, explains to STYLE how the maison’s new diamond source initiative will make the entire journey of its stones transparent to consumers by 2020
In case you hadn’t noticed, it’s the age of transparency. We demand to know where our handbags are crafted. We need to know what sort of cows our steaks come from, whether they were fed on grain or grass, how happy their lives were. It comes as no surprise, then, that the same applies to our jewellery.
As an industry first, Tiffany & Co. will now be laser-etching each of its individually registered diamonds sized 0.18 and larger with a serial number. Invisible to the naked eye, the serial number contains information about the stone’s region or country of origin – what the brand calls provenance – thereby ensuring consumers know where their diamond was sourced.
The move was partly motivated by millennials’ desire to be able to trace objects back to their origins, with brands held accountable for sustainability through their sourcing process.
“A transparent journey of responsible sourcing reflects the many positive and far-reaching benefits along every step of the diamond supply chain,” says the brand’s chief sustainability officer, Anisa Kamadoli Costa.
By 2020, the information included within the serial number will include details on the stone’s craftsmanship process, such as the workshop location in which the diamond was cut and polished.
