Book an AppointmentOur jewellery repair services restore your treasured pieces to their original beauty and functionality, offering expert repairs for broken clasps, worn prongs, loose stones, and other signs of wear.



Restore all kinds of jewellery, from intricate vintage designs to modern pieces.
From resizing rings to replacing gemstones, repairing chains, or refinishing worn surfaces.
Combining traditional techniques with advanced tools for precision in every repair.
Every piece tells a story, and we treat yours with the care and respect it deserves.
Adjust the size of your ring for a perfect fit — whether it needs to go up or down. We preserve the design integrity of even the most intricate settings.
Restore the original lustre and finish of your gold, platinum, or silver jewellery. Includes rhodium plating for white gold pieces.
Fix broken chains, replace worn clasps, and re-solder weak links. We work with all chain styles and metals.
Precision soldering to repair breaks, reinforce weak joints, or permanently join rings together for a seamless stack.
Source and set matching replacement stones for lost or damaged gems. We match the cut, colour, and quality of your original stone.
Rebuild worn prong tips to securely hold your stones. Essential maintenance that prevents stone loss from daily wear.
Repair bent, broken, or missing prongs. We reshape and reinforce the setting to keep your diamonds and gems secure.
Full restoration of antique, vintage, or heavily damaged pieces. We bring heirloom jewellery back to life while preserving its character.
Whether your ring no longer fits after weight changes, you've inherited a family heirloom that needs adjusting, or your engagement ring needs a perfect fit before the big day — Sergio handles every ring resizing in-house at our downtown Toronto studio.
We resize rings up or down by up to two sizes while preserving the structural integrity and design of the original piece. For rings with gemstones, we take extra precautions — heat-sensitive stones like emeralds and opals are carefully unset before resizing and reset afterward to prevent damage. Diamonds, sapphires, and rubies can typically remain in place during the process.
Ring resizing at OROSERGIO starts from $95 for simple adjustments, with most resizing completed within 3 to 5 business days. We work with all precious metals including gold (14K, 18K, 19K), platinum, and silver. Sergio will assess your ring during a quick consultation and provide an exact quote before any work begins.

Unlike chain jewellers that send your pieces to off-site facilities, every repair at OROSERGIO is completed in-house by Sergio and his team of fine artisans at their bench. Your jewellery never leaves the studio — from initial inspection to final polish, it stays in trusted hands.
“Sergio is an excellent jeweller with very reasonable prices and efficient services, who is additionally very kind. We met Sergio in 2019 when he engraved a pair of silver chevron couple rings for us. He did such a beautiful job that six years later we went back to his studio to have our wedding bands made! Everything from selecting ring styles and materials, fitting, and even same-day resizing (after I realized how much my ring size fluctuates with the temperature) was a smooth and seamless process. Thank you Sergio! If we have any additional jewelry needs in the future, we will absolutely be coming to you again :)”
“The best place to go for jewelry repair! The owners replaced my necklace chain on the spot and were so generous and kind. I would definitely come back to have anything custom made, as their custom pieces are all beautiful. Thank you so much!”

“When you read the name, you know that ORO is the translation for gold, and when dealing with Orosergio you certainly receive the Gold Standard. My family and I have been dealing with Sergio for years and have never been disappointed with any of his work or offerings. I am not one to write reviews but this one needed to be put in print. Its very easy to write a letter of complaint but praise is a more difficult task. Sergio takes immense pride in meticulous work for repairs or for something that he is making for you as a custom piece. Jewellery has been a showpiece all through history - to demonstrate wealth, taste, affluence, love, devotion… and Sergio takes the time to make sure that is well reflected no matter what your objective is.

“I recently had an outstanding experience with Orosergio's jewelry remaking service. I entrusted them with a gold band inherited from my grandfather and a pendant that was not to my taste, hoping to transform them into a 14k gold cigar ring. Orosergio exceeded my expectations in every way. They skillfully melted down the old pieces and crafted a stunning ring that fits flawlessly. The entire process was surprisingly quick, completed in less than a week. What also impressed me was their accessible online chat service, which was always responsive. Orosergio's professionalism and friendly demeanor added to the overall excellent experience. Additionally, their pricing was the most reasonable among several quotes I received in Toronto. For anyone looking to resize or redesign their jewelry, I highly recommend Orosergio for their exceptional service and craftsmanship.”
“I had a fantastic experience at Orosergio Custom Jewelry. I went in with a friend who needed his son’s little tooth turned into a gold pendant and this was one of the few jewellers that could and at a reasonable price. I myself had a gold chain that broke and every time I tried to get it fixed they would quote me a price that didn’t make sense until I found Orosergio Custom Jewelry. Impeccable customer services, reasonable prices, great time frame for work to be done. I would 100% recommend Orosergio Custome Jewelry for all your jewelry needs!!”
“I am delighted to share my exceptional experience at Orosergio. Sergio demonstrated an unparalleled commitment to providing superior service, in an industry where there are a lot of bad players.

My sincerest gratitude to Sergio for this one. This Orosergio has earned my utmost trust and will undoubtedly be my first choice for all future jewelry-related endeavors.”
“Helped me WELL beyond expectations. Went in here (Orosergio Custom design jewelry) to have one of my silver pieces repaired. I was in the area and needed a fix asap. I did a quick search and came across here and actually decided to come based on the positive reviews. I called to see how to make an appointment and was accomodated based on my timeline and urgency. Not only were they able to do it within record time but they were very friendly and accommodating from start to finish. They even gave me tips for better jewelry care as well as a 2nd to none experience. The service I recieved has been better than any previous experience at a jewelers and they clearly know what they're talking about and treat every customer with respect.

Your jewellery never leaves our studio. Unlike many jewellers who outsource repairs to third-party workshops, every repair at OROSERGIO is performed on-site by Sergio and his team. Your piece stays in trusted hands from start to finish.
You receive a detailed, itemized quote before any work begins. We explain what needs to be done, why it is necessary, and exactly what it will cost. No work is performed without your explicit approval, and there are never hidden charges or surprise fees.
Most standard repairs are completed within 3 to 7 business days. Complex restorations involving structural rebuilds, antique work, or custom stone sourcing typically take 2 to 4 weeks. Sergio provides an accurate timeline upfront so you can plan accordingly.
We aim to photograph your piece before and after every repair as part of our quality process. This documentation serves as an internal reference for the work performed and may be shared upon request when available.
Every repair undergoes a rigorous final inspection before it is returned to you. We stand behind our work and want you to be completely satisfied with the result. If something is not right, we will make it right.
We repair jewellery from any brand or maker, not just pieces created by OROSERGIO. Whether it is a department store purchase, a designer brand, or a family heirloom of unknown origin, we treat every piece with the same care and expertise.
Book an appointment at our studio. We’ll carefully inspect your piece and provide a detailed repair plan and estimate.
Expert restoration using the finest materials, combining traditional methods with modern precision.
Before your piece is returned, it undergoes a rigorous quality check to ensure perfection.
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.
Our studio is located in the heart of downtown Toronto on Queen Street East. We welcome clients from across the Greater Toronto Area and beyond. For those travelling from afar, we offer virtual consultations. Unlike chain jewellers that might send your pieces to off-site facilities, every repair at OROSERGIO is completed in house by Sergio or under Sergio's careful direction and supervision.
