Not The Basic Jewellers.

It started with a question about price.

My journey into jewellery began in a rather unconventional way. I had always been drawn to fine jewellery, craftsmanship and the individuality of custom-made pieces, but the turning point came when I commissioned jewellery for myself and began questioning the prices I was being charged.

I wanted to understand what went into creating these pieces, from the materials and manufacturing process to the craftsmanship behind the finished product. What started as curiosity quickly became an obsession. I invested in my own casting equipment, a small 3D wax printer and polishing tools, and began teaching myself how jewellery was made.

I still remember creating my first pendant. It wasn’t the most expensive or technically complex piece I’ve ever worked on, but seeing something go from an idea to a finished piece changed everything for me. It led to my first commissions, my own workshop and, in June 2019, to NTB Jewellers.

I’m largely self-taught. Rather than following the traditional route into the trade, I learned through research, experimentation, investing in equipment and, most importantly, hands-on experience. As the business grew, I began working alongside experienced professionals and specialist manufacturers.

Judged by eye, not just on paper.

When I select a diamond, I look beyond its size or the information on a certificate. The four Cs (cut, colour, clarity and carat weight) are extremely important, and the cut especially, because it shapes how beautifully the stone reflects light and how much brilliance and fire it shows. I also consider proportions, symmetry, polish and overall appearance, certification from respected laboratories such as GIA or IGI, and how the stone will complement the finished design.

“A diamond should impress you when you look at it, not just when you read its certificate.”

Both are genuine diamonds, with essentially the same chemical composition, physical properties and optical characteristics; they differ in origin, rarity and market value. We don’t push one over the other. We explain pricing, certification, long-term value and the character of each stone, so you can choose based on your own priorities.

For people who want something special.

NTB is for people who appreciate quality, individuality and a more personal approach to luxury. Some are celebrating milestones: an engagement, an anniversary, a birthday or a personal achievement. Others are passionate about fine jewellery, luxury watches and distinctive accessories, or have a creative vision they simply can’t find in a traditional jewellery store.

I don’t believe luxury should be defined by how much someone spends. It’s about the experience, the attention to detail and the feeling of owning something created or selected especially for you.

I make an effort to be approachable, transparent and personally involved, so clients feel comfortable asking questions and confident in their decisions. My aim is for people to return because they value the relationship.
