About us
Award-winning bespoke jewellery
Founded by Samuel Stirrat in 2017, Blackacre was born from a lifelong fascination with the natural world. Drawn to the colours, textures and formations of pebbles collected from beaches and streams, Sam's childhood curiosity gradually evolved into a passion for exceptional gemstones, craftsmanship and design.
Encouraged by his mother, an art historian and painting conservator, he discovered jewellery making at just 12 years old and began teaching himself the craft. Over the following decade, he refined his skills through relentless curiosity, experimentation and an uncompromising pursuit of excellence - developing the stone-first philosophy that continues to define Blackacre today.
The name Blackacre originated from Sam's first bespoke engagement ring commission, created for a couple who became engaged at a place in Cornwall bearing the same name. That commission captured everything the brand has come to represent: jewellery rooted in personal stories, crafted with intention and designed to endure.
Today, Blackacre creates fine jewellery that transforms life's most meaningful moments into modern heirlooms. From bespoke commissions to thoughtfully designed collections, every piece is centred around exceptional gemstones and guided by a belief that the most beautiful jewellery tells a story as unique as the person who wears it.
Our team
A team of experts
At Blackacre, our philosophy is simple: look after people, and people will look after you.
Our team is made up of qualified gemmologists, ensuring every consultation is guided by expertise. Laura and Minnie hold gemmology qualifications from both the Gemological Institute of America (GIA) and Gem-A, while Henrietta is currently completing her Gem-A qualification.
Every client, every story and every gemstone is unique, so our approach is always tailored to the individual. We take the time to educate and guide you through the design journey, helping you make informed decisions with confidence.
Built largely through personal recommendation, we believe exceptional craftsmanship begins with an exceptional experience.
Our mission
We believe the most meaningful luxury is personal, creating fine jewellery that transforms memories, milestones and identity into pieces designed to endure
The journey so far
Our journey is simply the evolution of a childhood dream. What started as a passion for collecting precious gems has escalated and evolved to where we are today.
A childhood dream
The founder
Although Blackacre was founded by Creative Director Samuel Stirrat in 2017, its story began much earlier. By the age of nine, Sam had already amassed a small collection of semi-precious gemstones, sparking a lifelong fascination with the natural world and the extraordinary beauty of rare stones.
A geographer by degree and an artist at heart, Sam combines a deep appreciation for geology, craftsmanship and design. His passion lies in sourcing exceptional gemstones and uncovering the unique stories they hold.
Preferring to remain behind the scenes, Sam is happiest sharing his knowledge with clients - guiding them through the world of gemstones and helping transform meaningful moments into one-of-a-kind creations.
Immersive jewellery
Bespoke experts
From the outset, our vision was simple: do one thing exceptionally well. Blackacre began by creating bespoke engagement rings, each designed to tell a deeply personal story.
As our clients' lives evolved, so did our creations. Today, we design one-of-a-kind pieces to celebrate life's defining moments - from engagements and anniversaries to milestone birthdays and new arrivals. Whatever the occasion, every piece is shaped around the individual and crafted to become a lasting heirloom.
The journey has always been as important as the finished piece, and that philosophy continues to define everything we create.
Our Expeditions
Artisan explorers
Think of us as modern-day explorers, adventurers and seekers of the exotic; we go to the ends of the earth to discover the most exceptional gems and craft designs around them.
Working directly with the individuals and communities that find the rare gems provides an unrivalled level of provenance - it's why our expeditions are at the heart of everything we do.
Frustrated with the lack of transparency, we've ventured to Sri Lanka and Colombia to bring you the story behind the stones.
