Apart from being the diamond capital of the world, Antwerp is also renowned for its fashion heritage. The city boasts one of the world's oldest academies and one of the most renowned fashion colleges. Many alumni belong to the top of the international fashion scene. Antwerp prides itself on workshops and stores of fashion talent from Antwerp and elsewhere. Add to this the trendy stores and exclusive concepts, and you get a good picture of fashion in Antwerp. Thanks to all these different facets, Antwerp is considered an outstanding fashion and shopping city, with good reason.

Bulwik believes jewelry is first and foremost a fashion item. But it is more than just a fashion accessory, it represents your own personality. Jewels can be perfect for showing your personal style, in the most elegant way.

Every collection Bulwik designs is a representation of our own visions and dreams, designed to add more beauty to your world. Our jewels are created for women who want to balance class and playfulness. Inspired by elegant lines and shapes, always making you feel confident and pretty.


Bulwik delivers uncompromised high quality. Each piece is handcrafted in 18karat gold by a skilled Antwerp goldsmith. We offer a perfect combination of pure craftsmanship and modern-day techniques.

Our jewelry is made with love and passion for detail.
Bulwik is a testament to our continuing commitment to quality. In all aspects of our business, quality control is our main focus. In the end, it’s our customers input and feedback we value most.
Our diamonds are 100% natural, conflict-free and certified by a diamond grading laboratory as a proof of quality. For certification we work with HRD and GIA.

Bulwik is committed to maintain the highest standards of social and economic responsibility. Our jewelry is crafted with precious metals that have been carefully sourced to reflect a commitment to social justice. Therefore, we make it our business to know who we work with. We collaborate with suppliers that source their materials in an ethical way. We only sell ethically sourced precious diamonds, extracted by responsible small-scale and artisanal miners.


Bulwik delivers an exclusive selection of high quality jewelry at prices that represent exceptional value.

We continuously strive to improve our product and our processes. We achieve our objectives by investing in our people, our processes and our technology. At a time when Antwerp is the world leader in the trade of diamonds, Bulwik is offering the best of what Antwerp has: quality, consistency and reliability.

We don’t hold an expensive inventory and operate only a small efficient showroom. That means our overhead is lower than traditional jewelers and we can offer lower prices to our customers.

Our efficient business model allows us to offer high quality diamond jewelry at prices that are unique in the industry but reflect the intrinsic value of the jewel. You pay the real price for what you get.

“ Buying wedding rings in Antwerp? In the classical jewellers shop you'll be waiting in line for at least half an hour on saturday. We made an appointment with Bulwik, and when we arrived, the staff was waiting for us and took their time to help. Thanks to their advice,
we found the perfect wedding rings! ”

“ My fiancé and me did'nt know anything about diamonds. Because diamond jewellery is not something you buy every day, we wanted to be sure of our choice. Bulwik gave us the perfect guidance and we knew right away wich rings matched our style. ”

“ As millenials we did'nt have a very big budget, so first we looked at some poor quality rings. Then we heard about Bulwik and by our surprise we could buy high quality diamond rings for a reasonable price within our budget.”

“I'm a man that doesn't like shopping. Especially if I have to stand and wait in a long line. So I made an appointment with Bulwik and I never had to wait, they were waiting for me and took the time to help me in my search for a ring. I appreciated that they gave me an extensive explanation because I didn't know anything about diamonds”

“As with many men, I was a little bit lost when trying to find the perfect engagement ring. I was afraid of choosing the wrong ring and letting my girlfriend down. Thanks to the advice of Bulwik, my fiancee is very happy with her engagementring”

“A woman proposing to a man? No, you don't see it that often. But for Bulwik that didn't make any difference. Together we chose a ring for my future husband that is stylish yet very masculine. He was defenitly surprised and he said YES!”

Buying a Bulwik jewel is at least as much a good experience as wearing one. There is no better way of enjoying that experience than to visit us in our Bulwik showroom or on our webshop.

We have a showroom in Antwerp and can receive clients for custom designs in Brussels as well.

Find us at Lange Herentalsestraat 62, 2018 Antwerp.
