What we can change

Six things you actually control

Most ‘custom’ suppliers mean one of these. We mean all six, and each one is priced as its own line so you can trade between them.

Material

925 sterling silver, 316L stainless steel, brass or copper. We will say when a design belongs in a different material from the one you asked for, and quote both so you can see the difference.

Plating

Yellow gold, rose gold, rhodium, black or steel blue, thickness stated in microns. PVD for steel, electroplating where a heavier micron count is needed.

Stone setting

Prong, bezel, pavé, channel or flush. Stone size, count and colour specified on the drawing; CZ, glass, crystal or natural stone.

Size run

US, EU/ISO or UK standards. Half sizes at no extra cost; the standard is fixed on the approved drawing so there is nothing to dispute later.

Your mark

Laser engraving, hand-stamping, a charm tag, a clasp tag or an inside-band stamp. We photograph the first marked piece for approval.

Packaging

Printed boxes, cards, pouches, belly bands and tamper seals. This is usually the cheapest way to make one order feel like a brand, and it is quoted as its own line.

The process

From brief to shipment in five steps

Every stage has a deliverable you approve before we move to the next one.

Send the brief

Sketch, reference or sample. Tell us the piece, the material, the finish and the quantity. A photograph with rough dimensions is enough to start — you do not need a technical drawing, and you do not need to know which material is right yet.

  • Send the brief, target retail price and market

CAD drawing

Within 48 hours. We produce a dimensioned drawing: weight, band or link sizes, stone counts, plating thickness and the position of your mark. Nothing is made until you approve this drawing, so changes are free at this stage and expensive afterwards.

  • Weight and tolerance stated on the drawing
  • Plating specified in microns, not as ‘gold plated’

Physical sample

In 7–15 days. The drawing becomes a sample in your material and plating. You wear it, photograph it and show it to your customer. Sample cost is quoted as its own line and credited against the production run, and what you approve is what we make.

  • Sample cost credited against bulk
  • One round of design revisions included

Production & QC

12–30 days. Production runs to the approved sample. Plating thickness, clasp cycle testing and stone security are checked on the run, and you get photographs at each milestone rather than a silent wait.

  • Photographs at every production milestone
  • Testing arranged for your market on request

Packing & shipping

Your route, your pack. Pieces are packed to your specification — pouch, card, box or polybag — then shipped by courier, air or sea. We quote the freight for your route so you compare landed cost rather than ex-works price.

  • Packaging quoted line by line
  • Freight quoted for your destination and volume

The difference

What a jewellery quotation usually hides, and what ours shows

Both columns describe the same order. The difference is whether you can check the number.

A typical quotation

  • בGold plated’ with no micron figure
  • ×One weight for the whole ring range
  • ×Sample cost not credited against the bulk order
  • ×Stone setting folded into a single unit price
  • ×Freight quoted after the order, not with it

What we put on the paper

  • ✓Plating thickness in microns on every line
  • ✓Weight and dimensions per size on the approved drawing
  • ✓Sample cost credited against the production run
  • ✓Stones, setting, findings and packaging as separate lines
  • ✓Freight quoted for your route so you can compare landed cost

Inside the process

How a custom piece is actually made

Six stages, each with something you inspect before we continue.

CAD drawing
Step 01

CAD drawing

Every custom order starts as a dimensioned drawing: weight, sizes, stone count, plating thickness and where your mark sits.

Master model
Step 02

Master model

The wax or resin master is cut from the approved drawing. Changes are cheap here and expensive later, which is why nothing is cast before you sign.

Casting
Step 03

Casting

Silver and brass are cast from the mould; steel is machined and formed. Either way the sample you approve and the production run come off the same tooling.

Polishing
Step 04

Polishing

Hand finishing decides how the piece reads in the hand. Mirror, satin, brushed and sandblasted finishes are all bench work, not print.

Plating
Step 05

Plating

PVD runs in a vacuum chamber and bonds at a molecular level; electroplating runs in a bath and can be laid on thicker. Thickness goes on the quotation either way.

Inspection
Step 06

Inspection

Callipers on the dimensions, a loupe on the settings and the finish, and clasp cycle testing on the closures. Photographs before the carton is sealed.

Private label

Take a stock shape, put your mark on it

Private label is the middle path between buying stock and developing a design. You choose a silhouette from the site, add your logo and size run, and we produce it under your name — with no design or tooling fee, because the shape already exists.

It is usually the right first step for a brand: cheaper than a fully custom design, far more defensible than unbranded stock, and it gives you something to photograph, price and sell while a bespoke collection is developed.

  • ✓No design fee on a stock silhouette
  • ✓Your logo engraved, stamped or on a tag
  • ✓Your size run and plating thickness
  • ✓Printed box, card or pouch with your artwork
  • ✓Retail-ready packing, quoted as its own line

Sampling

What sampling costs and what it buys you

Sampling is where a design is de-risked. We quote it as its own line and credit it against the production run, so the only real cost of sampling is the calendar.

StageTimelineWhat you getCost treatment

Timelines are planning figures and start from the day we receive your brief and any artwork. Material availability, plating colour and your market's testing requirements can move them.

Private label

Three shapes that are made to be re-marked

A flat or plain surface takes your mark cleanly, which is why these three come up first when a buyer asks for private label.

Sterling Silver Signet RingPrivate label

Sterling Silver Signet Ring

Solid 925 silver signet with a flat face for engraving — initials, a monogram or your own brand mark. Cast from your artwork, weight published per size.

Engravable Bar Pendant NecklacePrivate label

Engravable Bar Pendant Necklace

An engravable 316L stainless steel bar pendant on a fine chain. Laser-marked with your own coordinates, date or logo; tarnish-free, waterproof and safe for daily wear.

Oval Signet RingPrivate label

Oval Signet Ring

A cast brass signet with an oval face, made to be engraved with an initial, a monogram or your own brand mark. Casting holds a crisp edge around the face, and brass carries the weight of a solid signet at a fraction of the silver cost. Send a vector file or a sketch and the design work is a scaling exercise, not a new drawing.

  • ✓Your logo engraved on the piece, not just on the box
  • ✓Your size run and plating thickness, fixed on an approved drawing
  • ✓Your packaging, printed with your artwork and quoted as its own line
  • ✓No design fee on a stock silhouette — only the marking is new

OEM / ODM FAQ

What buyers ask before the first drawing

Including the two answers that are no.

Do I need a technical drawing to start?
No. Most projects start from a photograph with rough dimensions, a sketch on paper, or a physical sample posted to us. We turn that into a dimensioned drawing and send it back for approval, and that drawing is where the real conversation happens — weight, size standard, plating thickness and where your mark goes.
What is the minimum order for a custom design?
30 pcs per design in 925 sterling silver and in brass, and 50 pcs per design in 316L stainless steel. The minimum exists because a mould or a machining setup is a one-off cost, so reorders do not repeat it. Industry practice for steel is usually 50–100 pieces per style, which is why 50 pcs is a deliberately low start.
How much does a sample cost, and do I get it back?
Sampling is quoted as its own line because it depends on the material, the stone count and the plating. We credit the sample cost against your production run, so if you proceed the sample effectively costs nothing. One round of design revisions on the drawing is included; further rounds are quoted.
Can you copy a design I saw somewhere else?
We can work from a reference for proportion and construction, but we do not reproduce another brand's protected design, and we will not put someone else's logo on a piece. If what you like is a silhouette, we will develop a version of it in our own construction and show you the drawing first. If you want that exact protected piece, the honest answer is no.
What if I need the order for a specific date?
Tell us the date with the brief, not after the sample. Sampling (7–15 days) plus production (12–30 days depending on material) plus freight is the realistic chain, and testing for a regulated market adds its own lead time. If the calendar does not work we will say so immediately rather than take the order and miss it.
Can you develop a whole collection, not just one piece?
Yes, and it is more efficient than piece-by-piece development because the design decisions reinforce each other. Send the assortment you have in mind — how many rings, chains, earrings and charms, and the retail price points — and we will come back with drawings for the set plus the price per piece at your quantity.
