What are Lab-Grown Diamonds?

A truly wonderful experience

My husband and I visited Griffin & Co to order a white gold and diamond eternity ring for our 15th wedding anniversary, and we couldn’t have asked for a better experience. From the moment we walked in, we were met with warmth and genuine friendliness. The team were patient, never rushed us, and encouraged us every step of the way as we made our choices.

The ring is beautiful, and the care that went into the whole process made the occasion even more special. It’s something we’ll treasure, and so will the memory of ordering it.

I can’t recommend Griffin & Co highly enough. Thank you for helping make our anniversary so memorable!

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 1.8 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.

Can Jewellers Tell Lab-Grown Diamonds Apart?

A jeweller cannot tell a lab-grown diamond from a mined one by eye. Telling them apart takes laboratory instruments. Here is what they read.

Lab-grown diamonds avoid mining, but whether a stone is ethical depends on how the lab is powered and how it is graded. What to ask before you buy.

How to Read a Lab-Grown Diamond Certificate

What a lab-grown diamond report tells you, where it differs from a natural stone report, and why a certificate is a description and not a valuation.

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.
