Since 1935, Sifonios Jewellery has been a trusted name in fine jewellery, beginning with Nikolaos Sifonios and his wife Polymnia in the heart of Kos. What started as a passion for Byzantine craftsmanship has evolved into a family legacy, with each piece carefully selected to honour our heritage and serve our customers' most meaningful moments.

Today, Dimitrios Sifonios and Eugenia Kontoverou continue this tradition with intention and care. Rather than creating every piece ourselves, we curate an exceptional collection of fine jewellery that reflects our family's values and our customers' needs. From our physical stores in Kos to our online presence, we remain committed to offering jewellery that tells a story - your story.

Every item in our collection is chosen with the same dedication Nikolaos brought to his Byzantine creations. We believe the finest jewellery is not just about craftsmanship; it's about finding the perfect piece that becomes part of your family's journey, passed down and treasured for generations to come.
