The Guillaume Tissanié is a qualified jeweller who uses Sterling silver in his designs and each one is stamped with his personal hallmark.
In the interest of transparency and to always ensure the best possible quality, the brand sources the silver from only one supplier Cookson gold.
Working with a blowtorch and using the brazing method, the elements of each piece are made from a 925 or 950 alloy. They are then welded together using a silver/copper alloy. The final alloy will therefore depend on the number of welds but everything is done to ensure that each piece is of the best possible quality.
