The diamond usually gets the close-up. But turn an engagement ring sideways and there is plenty else to notice: the sweep of the band, the small supports beneath the stone and the claws holding it in place.
In Birmingham’s Jewellery Quarter, those details are part of a living craft. Birmingham City University’s School of Jewellery teaches traditional bench skills alongside digital design, with facilities for casting and laser welding. A computer screen and a jeweller’s bench belong in the same workshop. The planned Birmingham Jewellery Biennial will celebrate that combination of heritage and contemporary craft.
Lab-grown describes the diamond’s origin. The crystal is grown in a laboratory, then cut and polished before it is set into jewellery. Making the ring calls for a different set of skills: designing the setting, shaping the metal, securing the stone and finishing the surfaces.
Designing the setting: from sketch to 3D model
A solitaire and a halo ring can use the same centre-stone shape but need quite different metalwork. The lab grown diamond rings UK couples can browse at Lily Arkwright include solitaires and halos in gold and platinum. The smaller diamonds in a halo each need a place in the metalwork.
That framework has to work in three dimensions. From above, a ring might look airy and delicate. From the side, you can see how the setting connects to the band and where the bottom of the diamond sits.
Computer-aided design, usually shortened to CAD, lets a designer develop that structure as a digital model. A separate example comes from Jewellery Quarter manufacturer Hockley Mint, which describes its own bespoke process: a sketch becomes a CAD model, refined before a wax model is made for casting.
Casting an engagement ring in precious metal
In the casting process described by Cooksongold, wax models are enclosed in a mould and then removed. Molten metal fills the spaces they leave; after cooling, the castings are separated and finished.
At that point, the ring has its metal form, but it still needs work. Surfaces must be refined, attachment points cleaned up and settings prepared. The crisp outline in a product photograph does not arrive straight from the mould.
Casting is one route. Jewellers can also shape and join metal components, and a single ring may combine cast and fabricated parts. There is no universal production sequence behind every lab-grown diamond ring.
Setting the diamond securely
Stone-setting is where a small detail can make a considerable difference. In a claw setting, the diamond sits in carefully cut seats in the metal, known as bearings. Those seats need to fit the stone’s contour.
GIA’s stone-setting benchmarks explain why gaps matter: a poor fit can allow a diamond to move and eventually work loose. Closing claws over the top cannot compensate for a badly fitted seat beneath them.
There is a visual judgement here too. Claws are a small part of the ring, but they frame the stone. Their spacing and finish can make a setting look neat or awkward, even when you cannot immediately put your finger on the difference.
This is useful to remember when looking at enlarged ring photographs. The metal holding the diamond deserves a closer look as well as the diamond itself.
Finishing and polishing the ring
Polishing sounds like the final flourish. In practice, finishing can happen at several stages, including before stones are set, when recessed areas are easier to reach.
GIA’s guidance on finishing platinum jewellery includes the interior of settings and the need to preserve the design’s shape. Removing marks is skilled work: a crisp edge should not become a soft blur simply because the surface is shiny.
The inside of the band matters too. It is the part that spends the day against your skin, despite rarely appearing in the photograph that first catches your eye.
Hallmarking the precious metal
Birmingham Assay Office independently tests precious metals and applies hallmarks. A hallmark verifies metal purity rather than grading the diamond. New gold rings at 1g or more and platinum rings at 0.5g or more generally require a legally recognised hallmark when offered for sale in the UK. These weight thresholds exclude gemstones.
Next time you stop at a Jewellery Quarter window, look beyond the centre stone. Follow the curve of the metal beneath it, notice how the claws meet it and imagine the work needed to finish those small spaces. The diamond may catch your attention first, but there is a whole ring to appreciate.
