Blacklock Diamonds
A diamond is evaluated by its essential characteristics: cut, colour, clarity, and carat. However, we believe its true essence lies beyond these values. It requires a profound understanding or an intuitive 'feel' for the stone - a skill that has been passed down through generations of Blacklock. This expertise, honed through the handling and assessment of countless stones, is a privilege few experience.
At Blacklock, we find out whether a diamond has ‘life about it’, before unleashing it into the life of its owner.

Brilliance 40
Drawing from our rich diamond heritage, the Brilliance 40 collection was inspired by the pure beauty of a diamond. We've always believed that a masterfully cut stone stands apart, sparkling brighter due to the precise alignment of facets that maximize total internal reflection.
For the Brilliance 40 collection, we've handpicked stones with the highest cut grade — triple Excellent — ensuring excellent cut, symmetry, and polish. This level of craftsmanship transforms rough stones into polished gems of exceptional quality.
The collection plays off this ideal, with a creative expression of precision facet alignment embodied through an elegant octagonal halo and bevelled edged shank with a perfectly cut diamond at the centre. A true celebration of the Blacklock love of a perfect cut diamond.

Coloured Diamonds
A coloured diamond is a geological rarity, formed through the remarkable convergence of elements, minerals, gases, pressure and heat. These gems are among the rarest of the rare, available in a spectrum of hues from yellow and green to pink and blue. Their extraordinary display of colour is so mesmerizing that seeing is indeed believing.
At Blacklock, we love using coloured diamonds, whether as the centerpiece of a piece or as accentuating smaller stones.
Gemstones
Coloured Gemstones
Coloured gemstones fire the imagination. So we source only the finest stones to inspire our designers to push the boundaries of their next creation. For us, what truly defines a beautiful gemstone is its colour. The depth of a blue Madagascan sapphire from the Bemainty mine is comparable to that of a Kashmir sapphire. It is this profound knowledge and expertise that maintains Blacklock's position as one of the leading fine jewellers in the UK.
Our recent collections push the boundaries and bring together beautiful stones that compliment each other whilst making a statement. Whether it's the deep blue sapphires and pink opals of the Serpentine collection or the radiant aquamarines of the Neo collection - we display these magnificent gems to stunning effect.

Precious Gemstone Expertise
Ralph Blacklock was a Gemmologist and keen advocate to introduce new varieties of coloured stones to the Blacklock repertoire in the 1980’s. Often ahead of his time, he remained steadfast in his pursuit. In 1988, his discerning eye identified a green crystal at an auction, which was later revealed to be a 10-carat emerald.
Master Jewel: Maelstrom
Chris Blacklock spent months on a quest to secure the dazzling Paraiba Tourmalines for this extraordinary Master Jewel. Working with our trusted gemstone dealer, we were presented with several treasures from the Paraiba region of Brazil for evaluation. Our meticulous selection process guarantees that each stone meets our high standards for colour saturation and clarity.
The chosen stones boasted the unmistakable neon blue hue, thanks to traces of copper, and shone with an incredible luminosity and intensity that set them apart from all others. In short, they were simply more vibrant!
Complementing the Paraiba Tourmalines, we also sourced stunning royal blue sapphires from Sri Lanka and "gin and tonic" diamonds from India, all meticulously matched to the design specifications.In the end, we ensured that this piece showcases some of the finest coloured gemstones and diamonds available. This piece of jewellery is truly a marvel to behold.
