A bench jeweller is the person who actually makes and mends jewellery at the workbench. The title covers several trades under one roof: fabricating new pieces from sheet and wire, repairing and resizing existing ones, setting stones, and finishing work to polish and plating. Most bench jewellers do a mix of all four, and the mix decides the job.
The core skills
Everything at the bench rests on a handful of precise hand skills: sawing, filing, piercing, soldering and forming. Repairs — the bread and butter of many shops — add sizing, retipping prongs, rebuilding shanks and restringing. Stone setting is its own discipline, from bezels to prongs to pavé. Speed and consistency matter commercially: a jeweller who can solder a clean seam in one attempt saves the shop money on every piece.
Tools of the bench
The classic bench holds a jeweller’s saw and blade sets, needle files, pliers in a dozen shapes, soldering torch and blocks, a mandrel, hammers, burrs and setting tools. Beyond the hand tools, modern shops add ultrasonic cleaners, steamers, polishers and laser welders — but the hand skills remain the foundation everything else builds on.
Entering the trade
There is no single route in, but structured training shortens it dramatically. A foundation course such as Metalsmithing 1 at JDMIS teaches the bench skills on real projects — students leave with finished pieces and the muscle memory to continue; the pathway then runs through stone setting to casting and advanced techniques. Retailers increasingly hire from exactly this kind of trained pool.

Most metal jewellery made today passes through lost-wax casting at some point — the process that converts a wax or resin model into an identical metal piece. It is old (the oldest known cast objects are thousands of years old) and still the backbone of both mass production and one-off commissions.
The process, step by step
A model is made — carved in wax by hand, built in CAD and printed in resin, or cut from casting-sheet wax. The model is attached to a wax stem (the sprue) forming a tree, which is placed in a metal flask and surrounded by investment, a plaster-like material. Once set, the flask goes into a kiln: the burnout heats it in stages until the wax melts out and burns away completely — hence “lost” wax — leaving a negative cavity in the hardened investment. Molten metal is then forced into the cavity, by centrifuge, vacuum or gravity pour. After cooling, the investment is broken away, the cast tree is cut up, and each piece is cleaned, finished and set.
What designers must design for
Casting rewards designs shaped for it: consistent wall thickness, generous fillets where forms meet, sprue points placed where finishing marks will not show, and tolerance for the slight shrinkage of metal cooling in the mould. Thin sections that a fabricator could solder become cast failures; a designer who knows the process specifies what it can deliver.
Learning it hands-on
Casting is taught with real flasks and real pours in the precious-metal-arts programme at JDMIS — see MS400 Casting Metals & Advanced Stone Setting, built on the bench foundation of Metalsmithing 1. The digital route in, from CAD model to cast piece, is covered in the CAD track.

pearl shoppers meet two families: saltwater and freshwater. The distinction is about the mollusc and the water it lives in, and it shapes size, colour range, nacre quality and price.
Saltwater pearls
Saltwater cultured pearls come from oysters, generally one pearl (or a few) per shell, which is part of their cost. Akoya pearls — classically white, round and lustrous — set the image most people have of pearls. South Sea pearls grow large with soft satiny nacre in whites and golds; Tahitian pearls bring naturally dark greys, greens and aubergine colours.
Freshwater pearls
Freshwater cultured pearls grow in mussels, often many per mollusc, which makes them the most affordable real pearls. Modern freshwater pearls achieve round shapes and strong lustre that rival Akoya at lower prices, and their colour range — whites, peaches, lavenders — is wide. Nacre is typically solid rather than a thin layer over a bead nucleus.
What it means for buyers
Neither family is “better” — they are different tools for different designs and budgets. Judging lustre, surface, shape and matching across a strand matters more than the water the mollusc lived in. Pearl evaluation in context is part of the gem-trade training at JDMIS; start with the gem and jewellery trade course or the pearl masterclass.
Frequently asked questions
What is the difference between saltwater and freshwater pearls?
Saltwater cultured pearls come from oysters, generally one pearl per shell, which is part of their cost. Freshwater pearls grow in mussels, often many per mollusc, making them the most affordable real pearls with a wide colour range.
Are freshwater pearls worse than Akoya?
No - modern freshwater pearls achieve round shapes and strong lustre that rival Akoya at lower prices, with typically solid nacre rather than a thin layer over a bead nucleus. Judging lustre, surface, shape and matching matters more than the water the mollusc lived in.

Not every pearl comes out of a shell the same way, and the difference between the three kinds — natural, cultured and imitation — is the first thing anyone buying pearls should understand, because it drives practically all of the value.
Natural pearls
A natural pearl forms without any human intervention: a parasite or injury settles inside certain molluscs, and the animal wraps the irritant in layer upon layer of nacre. Natural pearls are rare today and command collector prices; most antique pearl jewellery predates culturing.
Cultured pearls
A cultured pearl is grown the same way — nacre around an irritant — but a technician starts the process by placing the nucleus. The mollusc does the rest over months or years. Nearly every pearl sold today is cultured, whether saltwater (Akoya, South Sea, Tahitian) or freshwater. Cultured pearls are real pearls; the word refers to how the process started, not to fakeness.
Imitations
Imitation pearls are manufactured beads — glass, plastic or shell — coated with a pearlescent finish. The classic “tooth test” (real nacre feels gritty against the teeth) separates most imitations, though some modern imitations pass casual checks, which is why professional gem testing exists.
Learning the pearl trade
Pearls and their imitations are covered in the gem-trade curriculum at JDMIS — see the GT100 gem and jewellery trade course — and the school’s free pearl masterclass is a good starting point.

Are cultured pearls real pearls?
Yes. Cultured refers to how the process started, not to fakeness - the mollusc lays down real nacre over months or years, whether saltwater (Akoya, South Sea, Tahitian) or freshwater.
How can you tell imitation pearls?
Imitations are manufactured beads - glass, plastic or shell - coated with a pearlescent finish. The tooth test (real nacre feels gritty) separates most, but some modern imitations pass casual checks, which is why professional gem testing exists.

Two stones can look identical to a casual eye and differ tenfold in price. The difference comes down to four value factors professionals weigh: colour, clarity, carat and cut.
Colour
In coloured stones, colour is the most important factor — hue, tone and saturation together. A stone with vivid, well-balanced saturation commands a premium over a pale or overly dark one of the same variety. In diamonds, the scale runs from colourless towards tinted, and the top grades carry steep premiums.
Clarity
Clarity is the presence of inclusions and surface features. Each gem variety has its own clarity expectations — some types almost always form with inclusions, so the standard differs by stone. What matters is how inclusions affect beauty and durability, not their mere existence.
Carat and cut
Carat is weight, and price rises non-linearly: a 2-carat stone of equal quality costs far more than two 1-carat stones, because large clean rough is rarer. Cut covers both shape and quality of fashioning — proportions that return light to the eye in faceted stones, and skilled shaping in cabochons. A poor cut drains value from fine rough.
Learning to judge
Practical colour description, clarity types, cutting styles and carat interpretation are taught hands-on with real stones in the gem curriculum at JDMIS — see the gem and jewellery trade programme for the full pathway.
Frequently asked questions
What are the four value factors for gemstones?
Colour, clarity, carat and cut. In coloured stones colour is the most important factor; clarity standards differ by variety; carat price rises non-linearly because large clean rough is rarer; and cut quality decides whether light returns to the eye.
Why does a 2-carat stone cost more than two 1-carat stones?
Because large clean rough is rarer. Price rises non-linearly with weight, so a 2-carat stone of equal quality costs far more than two 1-carat stones combined.
