The Blacklock Way

Understand our special values and how we work.

A dedicated approach


Every piece we make is unique

We believe we're creating more than jewellery. With each piece, we're offering a glimpse of the eternal, an heirloom to be passed through the generations. Whether you're looking for a creation inspired by our collections or you've got an idea of your own, we'll work with you to create a beautiful, hand-finished piece that is one of a kind.

Bespoke jewellery offers our Clients the opportunity to create and define their own luxury piece. This special process focuses on the Client and their own story and requirements. We focus on the smaller details that define the piece, elevating to create an irreplaceable jewel.

Attention to detail

An obsession with the fine detail

With the finest jewellery the finer details define us. Detail drives us at every turn from the selection of the smallest diamonds to understanding your discreet personal delivery requirements. We try to ensure each and every client has the attentive and personal experience they deserve. We are rigorous yet sensitive in our approach.

We carefully select our small diamonds (under 0.30cts) and have categorised them as follows;

Small diamonds labelled as 'Collection Quality', typically have the following specifications: D/E/F Colour & VVS Clarity

Stones labelled as 'House Quality' typically have the following specifications: G/H Colour & VS Clarity

It must be noted that stones under 0.30cts are generally not certificated.

The true secret of happiness lies in taking a genuine interest in all the details of daily life.

We've been sourcing diamonds for over 175 years

Choosing the right diamond or precious gemstone is as much as an art as is it as a science, and we take as much care with our sourcing as we do designing – investing a great deal of time in obtaining the rarest and most precious stones from trusted sources. Ralph Blacklock, Blacklock Partner and Fellow of The Gemmological Association of Great Britain, handpicks each stone for its fire, life and brilliance - and the certainty that you will love it as much as we do.

Our global network of suppliers all adhere to the Kimberly Process Certification Scheme, which means our diamonds never originate in zones of conflict. Every Blacklock diamond comes with a guarantee of authenticity and is responsibly sourced.

I only select stones that have real life about them; stones that speak to me where the play of light and colour is exceptional.

We create jewellery as individual as you are

The genesis of each Blacklock design begins with the individual diamond or gemstone. We draw upon what makes it unique –its innate beauty, clarity, cut and personality. The creative process is then based on one premise: that the design allows the stone to take centre stage, attracting and reflecting maximum light.

Inspiration comes from many sources – the magic of nature, legends or classical literature, such as the Forster-inspired Empire collection. Whatever the impetus, every Blacklock design blueprint is an original, characteristically feminine, yet strong and bold.

We only design jewels that we ourselves love. We invest ourselves in the design.

But I find that for myself, without exception, the more I deal with the work as something that is my own, as something that is personal, the more successful it is.

We work with the finest jewellery craftsmen

Craftsmanship is at the heart of everything we do. We're proud of our artisans and the mastery they bring, crafting precious metal and stones in harmony to translate our designs into works of beauty.

We work exceptionally closely with our craftsmen. As a small team with decades of experience everyone is on a first name basis and have grown with and love the Blacklock brand.

We check, refine and polish each piece by hand. And only once our standards have been met will we add the coveted 'RB' stamp – the sign of our family's knowledge and expertise since 1832.

Without craftsmanship, inspiration is a mere reed shaken in the wind.

Our family have been fine jewellers for six generations

Ever since Robert Blacklock sold his first diamond, our family has been helping people choose and create beautiful fine jewellery. That passion and expertise has been passed down through the centuries, from father to son, from the 19th century to today. Over the years our expertise has been recognised.

Experience is basis of our expertise. Knowledge that was passed to me by own Father, Kenneth Ellis Blacklock, is still of great value today. This knowledge has helped guide the business to become a bespoke fine jewellery company which crafts and creates timeless, contemporary jewels.

A proud tradition

Being an independent family jewellery business allows us to operate in a way that we believe is particularly British – that demonstrates our flexibility, entrepreneurialism, a dedication to service and the pursuit of excellence in the manufacture of the finest jewellery.

Central to this are the values that, through the generations, have become Blacklock hallmarks: trust, honesty and integrity. As you can imagine, it's a tradition of which we're particularly proud.
