Kotsonis Jeweler is a fine-jewellery house with an in-house workshop, where master makers and designers turn ideas into heirloom pieces. Beyond retailing jewellery, we design and handcraft custom commissions to each client’s brief - whether you’re seeking a unique engagement ring, a re-design of a family piece, or a fully bespoke set for a milestone occasion. Our workshop in Corinth blends traditional bench techniques with modern finishing to achieve enduring quality and impeccable detail.
Our collections span engagement rings, wedding bands, diamond jewellery, earrings, necklaces and pendants, bracelets, crosses, and full women’s, men’s, and children’s lines - available online and in store. This breadth allows clients to pair a bespoke centrepiece with complementary ready-to-wear pieces from the same aesthetic family.
We place special emphasis on wedding jewellery. For engagement, we offer a wide range of designs, (from classic solitaires to halo, three-stone, vintage-inspired and modern minimal styles), crafted in precious metals and set with natural or lab-grown diamonds. Select eternity (“seiré”) bands and wedding rings can be tailored for profile, width, finish, and pavé style, ensuring a precise match to your engagement ring and lifestyle. Our advisors guide you through stone choice, ring ergonomics, and budget, so every piece balances beauty, comfort, and value.
Quality is underpinned by careful material selection and certified gemstones. Diamonds and other stones can be supplied with reports from leading gemological institutes (e.g., GIA, IGL), and every finished piece is checked at the lab for setting integrity and finish. Aftercare options include sizing, polishing, and servicing to keep your jewellery looking its best.
Customer experience matters as much as craftsmanship. We provide clear product information online, secure checkout, gift packaging, complimentary shipping, and practical fulfilment options (including instalments). Our team is available to discuss bespoke projects, timelines, and design approvals before we move to production so you’re confident at every step.
Whether you’re choosing your first engagement ring or commissioning a one-of-a-kind piece, Kotsonis Jeweler brings together design, making, and service so your jewellery tells your story with precision and lasting beauty.

Brilliant service! They ordered us a coffee while we chose our ring, and were very patient with us.
They fixed and polished our broken jewellery and were very quick doing so.
Great collection and affordable price range.
Their Jewellery is stunning and hand made by them so they are unique.
We would definitely recommend to go there and purchase from them also plus they are lovely, friendly people and we really enjoyed their company.

Fantastic experience!!! They have plenty of products for both men and women from gold to stainless. What amazed me is the number of choices they have and the fact that you can customise your jewels from scratch. Very friendly staff but the guidance of Christina was beyond expectations!!! Totally recommend you to buy your jewellery from mr. Spyros!!!
