Repair and Redesign

Jewellery is so much more than a simple accessory – it’s a token of your past, a sentimental piece of memory that is a part of who you are. We know that sometimes jewellery can get broken or out of fashion and we are here to breathe new life into your old pieces!

Don’t sell your jewellery but instead redesign it into a timeless piece that will grow and stay with you throughout the years. We at Orosergio offer full repair and redesign services, ranging from retipping a broken claw to completely restoring a cherished family heirloom.
