All St-Onge creations are entirely drawn, produced, set (diamond setting) and polished in our Montreal workshop.

Gold Jewellery : At St-Onge Jeweller we only work with 18Kt gold. All our pieces of jewellery are made in solid gold and none are plated.

18k white gold : 24kt pure gold is yellow. In order to obtain white gold an alloy must be added to the yellow gold. At St-Onge Jeweller only palladium alloy is used in the manufacturing of our white gold jewellery. This alloy is best known for its hypoallergenic properties, compared to nickel which is widely used in products sold on the market and which can be very harmful. More than 15% of the population is allergic to nickel. The most common reactions in contact with this metal are rashes and small pimples on the skin. Our entire jewellery selection contains NO nickel.

18k yellow or rose gold : Silver and/or copper alloy is used in our yellow or pink gold pieces of jewellery.

Silver Jewellery :  Our silver jewellery is made of silver 925.

Platinum Jewellery : If you have a preference for Platinum, we can also produce your piece in this metal.

Yes! All our jewellery is made with hypoallergenic noble materials that are 100% nickel free.
