What we do
Any style, any metal, any stone.
We are a ring manufacturer for brands — not a catalogue of fixed designs. From solitaire engagement rings and eternity bands to signet, stackable, cocktail and fully bespoke pieces, we build to your spec.
Set them in solid gold from 9K to 24K (yellow, white or rose) or in platinum, with lab-grown or natural diamonds, moissanite, or coloured gemstones — every stone documented and honestly labelled.
Because CAD, casting, stone-setting and finishing all happen under one roof, you get one team accountable for the whole ring, source-level pricing, and the freedom to sample a single piece before you scale.
Why source from us
A ring manufacturer that controls the whole piece.
From the stone to the finished band, every step is in-house — better pricing, consistent quality, and one team accountable.
From stone to ring, in-house
We grow our own lab-grown diamonds, cut our own stones, and run CAD, casting and setting under one roof.
Any metal & stone
Solid gold 9K–24K and platinum; lab-grown & natural diamonds, moissanite and gemstones.
Certified & honest
IGI / GIA / GRA / GRC on request. Lab-grown and natural stones are clearly distinguished and labelled.

Settings & styles
The ring styles we manufacture.
A quick reference to the settings we build most. Mix any of these with your chosen metal and stone.
Solitaire
A single centre stone on a clean band — the classic engagement look.
Halo
A ring of small stones around the centre, adding sparkle and apparent size.
Three-stone
A larger centre flanked by two stones; often read as past, present and future.
Cluster
Several smaller stones grouped to read as one larger stone.
Pavé
Tiny stones set close along the band for a continuous line of sparkle.
Eternity
Stones set all the way around the band; popular for anniversaries.
Bezel
A metal rim wrapping the stone fully or partly — secure and modern.
Signet
A flat face for engraving an initial, crest or motif.
Bombé
A rounded, domed band with volume and presence.
Cocktail
An oversized statement ring built around a bold centre stone.
Bypass / crossover
The two ends of the band sweep past each other around the finger.
Stackable
Slim bands designed to be worn several at once and mixed.
How a ring is made
From a CAD file to a finished ring.
Modern ring-making blends digital precision with hand craftsmanship. Here is the path every order follows in our workshop.
1
Design & 3D CAD
Your idea becomes a precise 3D model. We confirm proportions, stone sizes and finger size, then send a render and quote within 48 hours — before anything is cut.
2
3D-printed wax pattern
The approved model is printed as a fine wax pattern. This captures detail hand-carving can miss and keeps every repeat piece identical.
3
Lost-wax casting
The wax is invested and burned out, then molten gold or platinum is cast in. We hold a safe minimum wall thickness so metal fills cleanly and avoids porosity.
4
Stone setting
Diamonds, moissanite or gemstones are set by hand — prong, pavé, bezel or channel — and checked for security and even alignment.
5
Polishing & finishing
The ring is filed, pre-polished and finished to your chosen surface: high polish, matte, brushed or hammered.
6
Hallmark, QC & ship
Metal purity is stamped, the piece passes a multi-point QC, grading reports are matched to the stones, then it ships securely worldwide.
Under one roof
Why in-house matters for your rings.
When design, casting, setting and finishing sit in one workshop, quality stays consistent and nothing gets lost between vendors. It also keeps pricing at source level and gives you one team accountable from first CAD to final polish.
It is the same reason we can move quickly on custom work and hold quality across a reorder.

Our workshop
Metals
Solid gold, 9K to 24K, and platinum.
Real, solid precious metal — not plating. Choose the karat that fits your market and price point.
| Metal | Purity | Character |
|---|---|---|
| 9K gold | 37.5% gold | Hard-wearing and economical; popular in the UK and Australia. |
| 10K gold | 41.7% gold | A durable everyday metal at an accessible price. |
| 14K gold | 58.5% gold | The most popular balance of durability, colour and value. |
| 18K gold | 75% gold | Rich colour and a premium feel for fine pieces. |
| 22K / 24K gold | 91.7% / 99.9% gold | Deep yellow, high-purity gold for bridal and high-gold markets. |
| Platinum (PT950) | 95% platinum | Dense, naturally white and hypoallergenic — the premium choice. |
Gold is available in yellow, white and rose. All metals are nickel-, lead- and cadmium-free.
Stones
Diamonds, moissanite and gemstones.
Every stone is documented and labelled for exactly what it is. Need pearl or jade for a special piece? We can source and set those too.
Lab-grown diamond
Grown in-house; chemically and optically identical to mined diamonds, IGI-graded, and clearly labelled as laboratory-grown.
Natural diamond
Earth-mined and sourced conflict-free under the Kimberley Process, with GIA or IGI grading on request.
Moissanite
A distinct lab-created stone — always sold and labelled as moissanite, never as diamond — with exceptional fire at a lower price.
Coloured gemstones
Sapphire, ruby, emerald and more, natural and lab-created, cut in-house for birthstone and statement rings.
Know your stone
Lab-grown vs natural vs moissanite.
Three popular choices, three different things. We never present one as another — here is how they compare.
| Lab-grown diamond | Natural diamond | Moissanite | |
|---|---|---|---|
| Origin | Grown in a lab | Mined from the earth | Created in a lab |
| Composition | Crystallised carbon (same as natural) | Crystallised carbon | Silicon carbide (a different material) |
| Hardness (Mohs) | 10 | 10 | 9.25 |
| Certification | IGI / GIA | GIA / IGI | GRA report |
| Relative price | Lower than natural | Highest | Lowest |
| How we label it | “Lab-grown diamond” | “Natural diamond” | “Moissanite” |
Every stone ships documented and labelled for what it is, in line with FTC guidance.
