Rennie & Co is a family run firm of Hatton Garden jewellers based at 105 Hatton Garden in London's EC1N diamond quarter, specialising in handmade diamond engagement rings, wedding bands and eternity rings. The Rennie family has held links to the jewellery trade since the 1950s, and today father and son Andre and Daniel Rennie continue to design and craft each piece in house. For couples planning a proposal or a wedding, the firm offers a discreet, specialist service built on GIA certificated stones and a long working knowledge of the quarter. This is a jeweller that treats a ring as an heirloom in the making rather than a quick sale.
Who Rennie & Co Are and Where to Find Them
Rennie & Co is a Hatton Garden diamond specialist offering bespoke and ready-to-wear rings from its showroom at 105 Hatton Garden, London EC1N 8LY. The shop sits within the heart of the quarter, a short walk from Chancery Lane and Farringdon stations, and opens seven days a week for browsing and consultations.
The firm focuses on diamond rings for life's defining moments, from engagement rings to wedding and eternity bands. Its full collection and contact details also appear on the Rennie & Co directory profile, where you can check opening hours before you visit.
Because the workshop and the showroom sit together, buyers can discuss a design and know it will be made by the same team. That continuity, rare on the high street, is part of what keeps couples returning to the same bench for anniversaries and remodelling.
A Family Name Rooted in the Jewellery Trade Since the 1950s
Few Hatton Garden jewellers can point to the depth of heritage that the Rennie family holds. With trade links reaching back to the 1950s, the family has accumulated decades of experience in jewellery design and manufacture, knowledge that passes down rather than out.
Andre and Daniel Rennie run the business today, and Andre has spoken of the pleasure of welcoming back couples who first visited to choose an engagement ring. As he puts it, as a couple's love grows, so often does their jewellery collection, from the first proposal ring to wedding bands and an eternity ring years later.
That long view shapes the work. Pieces are made to become cherished heirlooms, not items destined for the scrap pot after a few years of wear, and the firm's philosophy of exceptional service has stayed constant across the generations.


Handmade Diamond Engagement Rings With GIA Certification
Every Rennie & Co diamond ring is produced by hand to the firm's own exacting standards, with the design and manufacture carried out in its Hatton Garden workshop. For those preparing to propose, the engagement rings use exceptionally high colour, clarity and cut stones so the finished piece stands out.
Certification underpins that promise. The firm's diamond engagement rings are made with GIA certificated stones, meaning each diamond has been independently graded by the Gemological Institute of America for the 4Cs of cut, colour, clarity and carat weight. That independent record gives buyers confidence in exactly what they are paying for.
The firm's bespoke diamond ring service opens access to a wide selection of stones, including rare coloured gemstones alongside white diamonds. Buyers work with the maker to choose the stone, the metal and the setting, whether claw-set for maximum light or a more protective design for everyday wear.
Ethically Sourced Wedding Rings and the A. Gerstner Partnership
Rennie & Co takes provenance seriously. The firm deals only in diamonds from countries that adhere to the Kimberley Process, the international scheme intended to keep conflict diamonds out of the legitimate trade, a commitment set out on the Rennie & Co website.
Its wedding ring collection extends that care through a partnership with A. Gerstner, a maker founded in 1862. Together they offer ethically sourced wedding rings produced under strict human rights policies, with raw material sourcing that weighs social and environmental factors as defined by Responsible Jewellery Council certification.
For buyers who want a beautiful ring and a clear conscience, that combination matters. RJC certification is a recognised industry standard, and naming it gives couples a concrete assurance rather than a vague claim about ethics.
Eternity Rings and the Pieces That Mark a Marriage
An eternity ring marks a milestone, often a significant anniversary or the arrival of a child, with a band of stones that symbolises continuing commitment. Rennie & Co crafts an exclusive eternity ring collection in Hatton Garden, available to view in store or on its website.
Eternity rings come as full bands, with stones around the whole circumference, or half bands, with stones across the face only. Half-eternity designs sit more comfortably for everyday wear and resize more easily, a practical point worth raising during a consultation.
Because the firm makes engagement, wedding and eternity pieces under one roof, it can match metals, profiles and stone qualities across a set so that rings worn together complement rather than clash. That coordination is far simpler when one workshop holds the whole story.
Visiting the Showroom and Booking a Consultation
The Rennie & Co showroom at 105 Hatton Garden, London EC1N 8LY is open seven days a week, and the team welcomes both appointments and walk-ins. Staff are happy to answer questions, provide a quote or arrange a quiet consultation, and the firm points to its 5-Star rated TripAdvisor reviews as a measure of customer experience.
Before you visit, it helps to bring any inspiration images, a working budget and, for a surprise proposal, an idea of ring size. Ask about stone certification, hallmarking, resizing and lead times for bespoke commissions, and confirm what aftercare is included once the ring leaves the shop. No website can replicate the feel of handling a finished diamond ring in person, which is exactly why a visit to this established Hatton Garden jeweller is the natural next step.
