Your stunning jewellery is cast, hand set, and finished by our skilled UK based jewellers. We meticulously check every detail is perfect, add any personalisation you've chosen, and then your ring is carefully prepared for its journey to you.

Griffin & Co

I had a wonderful experience at Griffin & Co Fine Jewellery in Chichester. The quality of their jewellery is exceptional, and what really stood out to me was how reasonably priced many of the pieces are considering the craftsmanship. You can tell they take pride in offering high-quality items without the inflated prices you often see elsewhere.

The service was fantastic from start to finish. The staff were incredibly friendly, knowledgeable, and genuinely passionate about what they do. They took the time to chat, answer questions, and even shared some really interesting conversations about jewellery and design, which made the whole visit feel relaxed and personal rather than just a transaction.

If you're looking for beautiful jewellery, fair prices, and truly welcoming service, I highly recommend Griffin & Co. It’s a great place to shop and I’ll definitely be returning.

I couldn’t be happier with my experience.

Cian and the whole team were fantastic from start to finish. We were never rushed and were given plenty of time to consider our options. After some though, we asked Cian to design a ring for us, and the result is absolutely amazing. Would highly recommend

I used to go to the previous jewellers on this spot for years, so I popped into the new jewellers, Griffin & Co, on Monday to get a couple of rings repaired. They were badly bent and very dirty, so I wasn’t sure what to expect.

Later that day I received a call to say they were ready, beautifully repaired, professionally cleaned, and all free of charge. I was genuinely blown away by the service!!

Super friendly, honest, and clearly passionate about their work. I couldn’t recommend Griffin & Co more and will definitely be back and this place will definitely be by go-to jewellers!

Thank you so much :)

Service That Truly Stands Out

Bought a bracelet from Griffin & Co as a Christmas present, It looks stunning and I have no doubt that my cousin will love it! The staff are always amazing, especially Cian, who genuinely cared about making sure everything went smoothly. Exceptional service all around.

Frequently asked questions About Lab-Grown Diamond Engagement Rings.

Can’t find the answers you'r looking for? Our team is on hand from Tuesday to Saturday, 9:30am - 5pm.

How do lab-grown diamonds allow for a more exceptional engagement ring?

Lab-grown diamonds offer a compelling value proposition, often allowing you to secure a stone of greater carat weight or higher clarity within your budget. This empowers you to achieve a more significant visual presence and brilliance while maintaining an uncompromising commitment to ethical sourcing.

Can I design my lab-grown engagement ring using the 3D Studio?

Absolutely. This is the ideal starting point for your journey. Our 3D Online Design Studio allows you to step into the role of the designer—selecting your preferred cut, from a timeless Round Brilliant to a sophisticated Emerald Cut—and viewing photorealistic renders before our goldsmiths forge the final piece.

Are lab-grown diamonds considered "real" for an engagement ring?

They are indeed real diamonds. They are not simulants or substitutes; they are carbon-based crystals grown in a controlled environment. For the modern couple, they represent a forward-thinking approach to luxury—one that prioritises the planet and the future without sacrificing the prestige of a diamond.

Which metal best complements a lab-grown diamond engagement ring?

While all our recycled metals are exceptional, platinum is highly recommended for its natural white lustre and unparalleled durability. However, many prefer the romantic warmth of 18ct rose or yellow gold. We invite you to experience these tones in person at our Chichester showroom or via a Private Home Visit.

How long does it take to create a bespoke lab-grown engagement ring?

From the initial spark of an idea in our 3D Studio to the final polish at the bench, we ensure a seamless experience. We typically recommend 8–12 weeks to allow our master goldsmiths the time required for meticulous hand-crafting and quality control.
