What are Lab-Grown Diamonds?

They are created in controlled laboratory environments that replicate the natural conditions under which diamonds form in the Earth's mantle.

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 Jewellery.

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

Are lab-grown diamonds identical to natural diamonds?

Physically, chemically, and optically, they are indistinguishable. A lab-grown diamond possesses the same hardness, fire, and brilliance as a mined stone.

At Griffin & Co, we treat them with the same reverence as our natural stones, ensuring every piece is GIA-certified and set with meticulous precision by our master goldsmiths.

Why choose lab-grown diamonds for my jewellery collection?

Many of our clients choose lab-grown diamonds as a reflection of their values. They offer a sustainable, conflict-free alternative that reduces environmental impact without compromising on luxury.

When paired with our 100% recycled precious metals, the result is a piece of jewellery that is as ethical as it is exceptional.

Do lab-grown diamonds maintain their value and brilliance over time?

Yes. Because they share the exact crystal structure of natural diamonds, they are incredibly durable and resistant to clouding.

With professional care and the occasional polish at our on-site workshop in Chichester, your lab-grown pieces will retain their luminous fire for generations.

Can I mix lab-grown diamonds with natural stones in a bespoke commission?

Indeed. We believe luxury should be tailored to the individual. Whether you wish to pair a lab-grown centre stone with natural diamond accents or create a completely hybrid piece, our master craftsmen can execute your vision perfectly.

This can be explored via our 3D Online Design Studio or during a private consultation.

How does Griffin & Co differ from mass-market lab-grown retailers?

The distinction lies in the making. Most retailers simply sell a pre-cast ring; we are true makers.

Every piece is sculpted and finished at our bench in Chichester, ensuring the setting is as precise and enduring as the diamond itself. We provide a luxury concierge experience, not a transactional one.
