Ethical and Sustainable Fine Jewellery

Welcome to the House of Blacklock. Pioneering designs and exceptional craftmanship is in our blood. They are yours to be discovered.

Pioneers of Elegance Since 1832

Founded in 1832 in the midst of the shipbuilding boom, Blacklock Jewellery soon became the leading Diamond Merchant and ‘county’ jeweller for the North East of England. As pioneers in fine jewellery, we invite you to explore our story.

Bespoke Elegance

A bespoke Blacklock jewel is a true expression of individuality. Every last detail is a reflection of your style, while the result is a perfect blend of craftmanship and storytelling. From the finest stones to design detail we engage you to experience the finer details and define true luxury.


Collections that take inspiration from ideals to nature and beyond. We are not limited in how we bring these concepts to life through the application of exceptional design, the finest goldsmithing, diamond and precious gemstone setting and finishing.

Brilliance 40

Scintillation of a diamond is maximised when the pavilion angle is cut to 40 degrees. This signature collection embodies this ideal with maximum effect.


A collection which celebrates the Give Women Votes movement. A bold design which features a stunning central green emerald.

Sustainably Sourced Diamonds and Gemstones

A timeless diamond or bright and bold precious gemstone takes thousands of years to form. We feel it is our duty to try to protect the earth and the beautiful gifts it gives us. All of our diamonds and gemstones are sustainably sourced.
