Design Your Own Engagement Ring

Choosing an engagement ring does not have to mean choosing from what happens to be in a display case. Start from the stone itself: browse certificated natural and lab-grown diamonds, compare them side by side, then pair the one you choose with a setting made in our Hatton Garden workshop.

How It Works

STEP ONE

Choose Your Diamond

Browse live availability and filter by shape, carat, colour, clarity and budget. Every stone is independently graded, and the certificate is shown before you commit.

STEP TWO

Choose Your Setting

Pair your diamond with one of our engagement ring settings, from classic solitaires to halos, trilogies and vintage designs, in platinum or gold.

STEP THREE

We Craft It In Hatton Garden

Your ring is made and finished at our workshop at 9 Hatton Garden, then checked, polished and presented ready for the question.

Why Build Rather Than Buy Off The Shelf

Two rings with the same headline price can hold very different stones. When you start from the diamond, you decide where the money goes: a larger stone in a simpler mount, or a smaller, better-cut stone with more detail in the setting. Our guide to the Four Cs explains the trade-offs in plain English, and diamond shapes covers how each cut behaves on the hand. If you are working to a number, setting a budget shows what to expect at each level.

Frequently Asked Questions

Are the diamonds certificated?

Yes. The stones in the builder carry independent grading certificates, and the certificate is visible on each diamond before you buy.

Can I see the diamond before committing?

Yes. Choose a stone online, then book an appointment at 9 Hatton Garden and we will have it ready to view alongside comparable options.

Natural or lab-grown?

Both are available in the builder. They are the same material with the same optics; the difference is origin and price. Our guide to lab-grown diamond prices explains the gap honestly, including what it means for resale.

How long does it take?

It depends on the setting and the stone, and we will give you a realistic date when you order rather than a hopeful one. If you have a proposal date, tell us and we will work to it.

What if the ring does not fit?

Resizing is free, up or down. See our guarantee for everything included after the sale.

My experience with Smith & Green Jewellers was exceptional from beginning to end. Choosing our engagement and wedding rings was such an important milestone, and Josh made the entire process feel personal, enjoyable and completely stress free.

★★★★★

Honestly couldn’t recommend this place anymore, incredible service from start to finish. Josh and Chris were both top guys, offered lots of wisdom support and advice without putting any sort of pressure on me, and offered so much flexibility during the process that I know I wouldn’t have got elsewhere.

★★★★★

After numerous visits to Hatton garden and not finding what I wanted or someone I trusted to design my ring, I eventually and thankfully found Smith & Green. They helped create the perfect ring, everything I wanted from a special purchase to celebrate having my 2 little girls.

★★★★★

I visited the shop in December, everyone at the shop was super helpful, Valentina did an excellent job, the ring came out stunning. During my day there I learned a lot about diamonds and really felt like they cared about ensuring I got exactly what I thought my now fiancé would love.

My experience with the Smith & Green Jewellers while purchasing engagement and wedding rings was absolutely fantastic. From the moment I stepped into the store, I was met with warm hospitality and genuine enthusiasm from Mr Joshua Green.
