I came across Stefan’s website while looking for someone to repurpose my old jewellery. I reached out to quite a few jewellers but didn’t hear back from most of them. Stefan was the only one who responded, and he did so quickly and professionally from the get-go. He transformed my old jewellery into four beautiful new pieces, and I couldn’t be happier with the result! Throughout the whole process, he kept me updated, communicated clearly and made everything so easy. His prices are competitive, and he’s genuinely a lovely gentleman to deal with. If you’re looking for a reliable, professional jeweller who takes pride in his work and delivers great service, I can highly recommend Stefan. Thank you, Stefan, for bringing new life to my old jewellery and making the whole experience such a pleasure! ❤️Posted on Google![]()

Searching for a special anniversary gift for my wife during an extended visit to Cape Town, I came across Stefan's shop through a Google search and decided to check him out after reading his reviews and going to several larger and more "traditional" jewelry establishments in the city's malls, the V & A Waterfront, etc. No doubt, Stefan's shop is a much smaller operation, but the personalized attention and expertise that Stefan offered rivaled any of the other places I had visited. Stefan helped me land on uniquely-designed Tanzanite ring in 14 carat white gold at the perfect price point. My wife is going to love it! Also, as a foreign national only visiting South Africa, Stefan walked me through the VAT refund process and supplied me with the necessary declaration invoice that I will need to present upon departure. In short, I highly recommend Stefan. He strikes me as very trustworthy and dependable. Moreover, he gave me ideas for pieces that can be designed for me during my return visit to Cape Town! I look forward to not having to waste my time scouting around Cape Town for that perfect piece at a fair price. I'm going straight to Stefan! If you want that personalized touch, Stefan is your guy!Posted on Google![]()

I couldn’t be happier with our rings! Stefan was incredible from start to finish—professional, patient, and genuinely passionate about his work. He took the time to understand exactly what we wanted and made the whole experience so easy and enjoyable. My pear-shaped engagement ring is absolutely stunning, and my fiancé’s wedding band is just as perfect. The craftsmanship and attention to detail are exceptional, and the quality exceeded our expectations. Thank you, Stefan, for creating such beautiful rings that we’ll treasure for the rest of our lives. I would highly recommend you to anyone looking for a trustworthy jeweller who truly cares about making your vision come to life!Posted on Google![]()
