About Louise Sinclair
Find out how Louise’s journey as a gemologist and personal jeweller began over 30 years ago. Her designs reflect her devotion to empowering modern-day women through glamorous yet practical collections that speak the language of women from all walks of life. Louise has championed a timeless style that masters the balance between comfort and design flair, which translates to her collections and bespoke commissions alike.
I absolutely love creating jewellery that complements and enhances a woman’s confidence, playful personality, and intrinsic elegance.
World-class credentials & expertise
Louise’s journey began in 1992, when the allure of Burmese rubies, Colombian emeralds and Kashmiri sapphires first captivated her. Determined to turn passion into profession, she earned her gemology and diamond diplomas from the Gemmological Association of Great Britain — the oldest and most respected jewellery education provider. Today, she holds Fellowship (FGA) and Diamond Membership (DGA) credentials, recognised worldwide for their rigour and excellence.
Deep industry insight & connections
Over thirty years in the trade, and as a familiar face in London’s Hatton Garden, has given Louise unparalleled insight into the gem market. Her close ties with trusted dealers and international bourses ensure she can source exceptional stones at highly competitive prices, benefiting every private commission and collection she creates.
Jewellery inspired by the demanding lifestyles of modern-day women
As a mother and entrepreneur herself, Louise’s designs are inspired by real-life demands — pieces that not only keep up with a busy lifestyle but also empower today’s woman. Her signature lies in marrying glamour with practicality, without sacrificing one for the other, and articulating a timeless style that takes women effortlessly from meeting to evening soirées.
Wearability is key!
While her collections are often inspired by her fascination with ancient civilisations and iconic movements, Louise’s designs blend these influences seamlessly with a contemporary tone. Above all, wearability is key!
To me, the practicality of a piece of jewellery is vital. It needs to be comfortable and easy to wear. Only when it is worn does it become valuable.
This is why my intention is always to craft pieces that are flexible enough to be worn to any occasion, with any outfit, by women of all generations. Simplistic and clean lines ensure the designs do not date.
The power of coloured gemstones
Louise is captivated by the expressive power of colour and how it reflects our personalities and uplifts our moods. Her bold, vibrant jewellery showcases her mastery of exotic stones, set within minimalist silhouettes that allow each gem to speak for itself.
The timeless and sentimental value of a bespoke piece
Louise’s gift for understanding each client’s story enables her to transform personal visions into unforgettable, one-of-a-kind creations. As a trusted personal jeweller, her bespoke commissions have immortalised life’s milestones — from engagements and anniversaries to graduations and family heirlooms.
A key part of Louise’s practice is reimagining inherited pieces: she expertly remodels treasured heirlooms into contemporary designs that can be worn, loved and passed on for generations to come.
Clients come to me with inherited pieces to be remodelled for various reasons. However, ultimately, the goal is always to preserve a family’s legacy through a keepsake that can continue to be worn by current and future generations.
Sustainability
Louise is deeply committed to ethical and sustainable practices. She works exclusively with refined gold and conflict-free diamonds certified under the rigorous Kimberley Process and compliant with United Nations resolutions.
A veteran of the industry, she also champions English craftsmanship by supporting Hatton Garden’s artisan community and hosting private workshops to preserve these highly specialised skills.
Giving Back
Beyond her dedication to ethical practice, Louise Sinclair actively supports charitable initiatives both in the UK and internationally.
Since 2021, she has backed the Dusty Yak Foundation, which funds care for children and orphanages in Nepal, and has lent her support to Tommy’s campaign — the UK’s leading charity for pregnancy and baby loss research. In September 2024, Louise contributed a custom piece to the Royal Marsden Cancer Charity auction, helping to raise vital funds for one of the world’s foremost cancer treatment centres.
