Run by Master Goldsmith Sergio Chamahyan, the Orosergio Ltd. Studio is all about providing exceptional quality service and exquisite pieces of jewellery to meet and exceed your highest standards.  With more than 20 years of experience, Sergio combines talent with passion to produce one-of-a-kind jewellery to reflect the unique personality and style of each and every client. Designed with the uttermost care for details and meticulous approach towards perfection, Orosergio’s jewellery are only the finest quality pieces that will stay with you for the years to come.  We at Orosergio work with only the best materials, including platinum, all karats of gold in every color possible, and genuine conflict-free diamonds and precious stones. In fact each and every one of our diamonds is acquired and certified according to the Kimberley Process, a government, civil and industry initiative aimed at stemming the trade in conflict diamonds.

We believe in working not only for, but with our clients and we welcome you to be a part of the jewellery crafting process. Book a free consultation with our designer Sergio and create your dream jewellery from scratch. We begin with a sketch that will be refined until we’re sure we’ve met all your needs and requirements and then create a CAD model based on it. From the initial concept to the final product, we pay specific attention to every single aspect of the jewellery crafting process. We will hand-select the stones and refine everything through the minor features to ensure your vision is fully accomplished. Be a part of the jewellery crafting process and create your own unique piece of jewellery!
