Jewellery Repair in Toronto

We offer a comprehensive range of jewellery repair services at our downtown Toronto studio. This includes ring resizing (both up and down), chain and clasp repairs for necklaces and bracelets, stone replacement for lost or damaged gems, prong tightening and rebuilding, polishing and rhodium plating, soldering broken pieces, and full restorations of antique or heavily worn jewellery. Whether your piece needs a simple fix or a complex multi-step restoration, Sergio has the expertise and equipment to handle it. We work with all precious metals including gold, platinum, and silver, as well as all types of gemstones.

Most standard repairs such as ring resizing, chain soldering, clasp replacement, and prong tightening are completed within three to seven business days. More intricate work, such as full restorations of antique pieces, custom stone sourcing, or structural rebuilds, may take two to four weeks depending on the complexity involved. Sergio will provide you with an accurate timeline during your initial assessment so you know exactly what to expect. If you have a time-sensitive situation such as an upcoming wedding or special event, please let us know and we will do our best to prioritize your repair.

Yes, replacing broken or missing gemstones is one of our core specialties. We carefully source replacement stones that match the cut, colour, clarity, and size of your original gem so the repair is virtually undetectable. For diamonds, we hand-select stones that match the existing pieces in your setting. For coloured gemstones such as sapphires, emeralds, and rubies, we work with trusted suppliers to find the closest possible match. If your original stone is chipped rather than lost, we can evaluate whether recutting is a viable option before recommending a full replacement.

We believe in complete transparency when it comes to pricing. During your initial consultation and assessment, Sergio will carefully inspect your piece and provide a detailed, itemized quote before any work begins. You will know exactly what the repair involves, why each step is necessary, and what it costs. We never proceed without your approval. Repair costs vary depending on the type of work, materials needed, and complexity — a simple ring resizing is significantly less than a full antique restoration. There are no hidden fees and no surprises. Our goal is to build trust through honesty and deliver exceptional value for every repair.

Yes, we offer professional jewellery cleaning, polishing, and inspection services that go far beyond what at-home cleaning can achieve. Using ultrasonic cleaning technology and high-pressure steam, we remove built-up oils, lotions, and debris that accumulate in settings and on stone surfaces over time. We also inspect every prong, clasp, and link under magnification to identify early signs of wear that could lead to stone loss or structural failure. For pieces created by OROSERGIO, we offer complimentary cleaning once a year as part of our commitment to our clients. We also extend complimentary cleaning to clients who are commissioning a new piece with us — for example, if you are ordering a wedding band and bring in your engagement ring from another jeweller, we are happy to clean it at no charge. For all other pieces, our cleaning service is affordable and thorough, and we recommend scheduling it at least twice a year to keep your jewellery looking its best.
