Good customer service

Required a wedding ring to be repaired and resized. Good competitive quote offered and work completed quickly and well. No issues at all and would happily recommend to others.

Mark Lynch

I couldn’t recommend Griffin & Co Jewellery in Chichester highly enough. The service was outstanding from start to finish, with a genuinely friendly, professional and personal approach that made the whole experience a pleasure.

The team were incredibly helpful, knowledgeable and attentive, taking the time to understand exactly what we were looking for and ensuring every detail was right. The quality of the jewellery is exceptional, and it’s clear they take real pride in both their products and the service they provide.

It’s refreshing to find an independent jeweller that combines such high standards with a personal touch. I wouldn’t hesitate to recommend Griffin & Co to anyone looking for beautiful jewellery and a first-class experience.

A fantastic local business that truly deserves its reputation. I’ll definitely be returning!

The most beautiful ring ever!
I won one of their brilliant treasure hunt giveaways in September and as my prize I got to design my own ring! I got to choose from a selection of precious stones and then chose the cut and the setting. I went with a teal sapphire and it’s is the most stunning shade of green. I just came back and collected it just 3 weeks after winning :)
Amazing service, super friendly staff who were all just as excited as I was that I won!
Can’t recommend them enough

I had been doing research on engagement rings for ages before finally settling on buying one from Griffin and Co. - Fab website with full 360° views of each of the diamonds I was interested in and pulled out all the stops to get the ring hand delivered to me in time for our holiday to Italy. Now fiancée very pleased with the ring and even managed to pop into Hatton Garden to get it resized when we got home. Top service from Cian and the team!

My purchase of Bespoke Jewellery @ Griffin & Co I recently commissioned a bespoke natural 1

My purchase of Bespoke Jewellery @ Griffin & Co

I recently commissioned a bespoke natural 1.8 carat diamond trilogy ring and a pair of diamond studded huggie style earrings. It was not an impulse purchase and took several weeks to conclude.

I chose to go along the bespoke route rather than buy ready made pieces because I wanted my ring and earrings to complement the jewellery I already owned & wore on a daily basis.

After an initial consultation with Erin, a member of Cian’s team, I did extensive research online. Buying diamonds is a complex affair - there are so many factors to consider when choosing natural diamonds - size, cut, colour, clarity etc. All of these can affect not only the price, but also appearance.

Having educated myself, to an albeit basic level, I was able to better judge Cian’s input about design, quality and price. I was impressed by his provision of a detailed breakdown of costings & computer generated photographic images. This information enabled me to evolve the jewellery design, to decide which diamonds to specify and the price to pay.

Cian then sourced the diamonds from his London supplier and arranged for his Emsworth workshop to create a 3D silicon model of the ring. This meant I could try the image of my imagination on my actual finger. Subsequenty, I did slightly change the ring setting, so it was a really useful part of the bespoke process. Finally I was able to place my order. Cian & his team had been very patient.

My combined bespoke purchase of a ring and earrings took about a month to complete: time to obtain the GIA certification I stipulated for the trilogy ring diamonds, for the jewellery pieces to be actually crafted and for them to be sent away for hallmarking.

Could I have ordered direct from an online supplier and paid a cheaper price? In theory, yes. But I didn’t feel I could trust the integrity of such a source for a product as complex & nuanced as natural diamonds. And how could I have faith in the quality of the jewellery workmanship if I bought online?

No, having benefited from Cian’s knowledge of gemstones and advice on jewellery design, I decided instead to accept the fair price we negotiated & give Griffin & Co my order.

I am delighted with both my trilogy ring & diamond earrings. And I know if I ever need to resize my ring or I want to have the jewellery cleaned or checked for security of settings or clasp, Griffin & Co will willingly provide this as part of their after sales service.

I have no hesitation in recommending Cian & his team at Griffin & Co for bespoke and very fine jewellery.

I lost the diamond out of my engagement ring and couldn’t afford a new one so Kian organised a selection of coloured stones as a cheaper alternative option. I chose pink Topaz and it looks absolutely gorgeous, I love it! He also re rhodium plated the ring for me. He is extremely kind and helpful and we will definitely be long term customers.

My husband and I had a fantastic experience today in Griffin & Co. Cian helped make picking a ring for my birthday a really special experience with his expert knowledge, great customer service and honesty and transparency on the products I was looking at.

Will definitely be coming back for future purchases- thank you!

I lost the original stone in a signet ring that has been in my family for many generations. Other jewellers, both here and in Dubai attempted to match the original, but failed miserably! Cian and the team at Griffin not only found the perfect match to the original, but, returned the ring looking like new. It doesn’t have any great monetary value, but it’s sentimental value and part in my family history, tell a story that can now continue. I’m absolutely delighted and can’t recommend d Griffin and Co enough.

Thank you

Are Lab-Grown Diamonds Real? An Honest Answer

A lab-grown diamond is a real diamond: same material, same optical properties, independently graded. Here is what the difference actually is.

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.
