After graduating in 1972 from the Gemological Institute of America (GIA) in California, Robert St-Onge was hired as a gemologist at Henry Birks & Sons Jewellers. Five years later, he opened his own shop while continuing to work closely with the renowned jewellery retailer.

The years he spent refining his craft shaped St-Onge’s desire to create his life’s work – his own line of unique, sophisticated, high-quality jewellery. By establishing St-Onge Jeweller, he was then in a position to bring together superior craftsmanship, exclusive custom-designed creations, along with the values of honesty and respect, all of which have contributed to his unequalled reputation.

Just as each individual is unique, so is every precious stone. The piece of jewellery becomes a testimonial to an exceptional story – your story. Its very existence will celebrate your rich history, and express the beauty and depth of your feelings. These very feelings are the source of our inspiration, as we truly believe there is nothing more beautiful than the way you cherish the people you love.

We combine the outstanding quality of a large jewellery retailer with the exceptional customer service of all small family-owned business. We share your love for the finer things in life and for the values you hold dear. We foster a common love of family and seek only what is the best for your loved ones. We safeguard our reputation by never compromising on the quality of our manufacturing processes or of our precious stones.

  • 100% of our jewellery is made in our workshops in Montreal
  • We are committed to using high-tech equipment and leading-edge technology to achieve optimal design results.
  • The white gold used in our jewellery is hypoallergenic and contains a mixture of palladium, which will not tarnish, as opposed to nickel which can cause itching and redness.
  • The gold, platinum, and silver in our jewellery is cast without porosity, cracks, or pores, which could weaken its strength and detract from its appearance. You can therefore be sure that the piece of jewellery you own is very resistant and durable.
  • Our precious stones are carefully selected to meet our superior quality standards.
