What is Bezel?

Bezel is a hands-on jewelry design sketchpad for iPhone and iPad. Instead of generating a flat picture, you compose a piece part by part — setting, stone, band, chain, clasp, charm — from a curated component library, and every part carries real dimensions in millimeters, carats, ring sizes, and chain lengths.

An Apple Pencil layer sits over the composition, so you can freehand a custom pendant shape, mark solder points, or annotate the design the way you would on a bench sketch. Swap any part and the rest of the piece stays put.

When the design is settled, Bezel exports a clean spec sheet — the rendered piece plus a parts list with sizes — that works as a shopping list for your supplier or a work order for the bench. Boards keep variations of one design side by side, silver band next to gold, oval stone next to round.

Features

Part-by-part composing

Drag settings, stones, bands, chains, and clasps from a parametric library. Swap any part and keep the rest.

Real dimensions, not vibes

Every part carries metric and imperial sizes, with ring-size and chain-length pickers and a live total-length readout.

Apple Pencil sketch layer

Freehand custom shapes, annotate the design, and mark solder points right over the composed piece.

Spec-sheet export

Render a clean PDF or PNG with the piece and a dimensioned parts list you can take to a supplier.

Boards for variations

Save versions of one design side by side to compare metals, stones, and settings before committing.

Editable, always

Nothing is a flat render. Move, resize, and re-spec any component at any point in the design.

How it works

Pick your parts

Browse the component library by family — settings, stones, bands, clasps, chains — and drop parts onto the canvas.

Set the real sizes

Choose stone diameter in mm, band width, ring size, chain length. The readouts update live as you adjust.

Refine with the Pencil

Sketch one-off shapes, add notes, and mark solder points on the freehand layer over the parametric parts.

Export the spec sheet

Generate a PDF with the rendered piece and its parts list, ready for the supplier order or the bench.

Frequently Asked Questions

Is there an app to design jewelry before buying materials?

Yes. Bezel lets you mock up the full piece — setting, stone, band, clasp — with real dimensions before you order anything. Because the exported spec sheet doubles as a parts list, you know exactly what to buy and in what sizes, instead of guessing at the bench.

How do I design a ring with accurate measurements?

Every component in Bezel is parametric: stones are sized in millimeters and carats, bands in width, and the ring itself in standard ring sizes. Change a size and the piece updates, with a live readout, so the design you see matches the metal you will cut.

What is the difference between an AI jewelry generator and a design app?

An AI generator produces a flat image — often pretty, but you cannot move the stone, resize the band, or read a single dimension off it. A design app like Bezel composes the piece from editable parts that carry real sizes, so the result is a buildable plan rather than a mood picture.

Can I sketch jewelry with Apple Pencil?

Yes. Bezel layers a PencilKit freehand canvas over the parametric parts, so you can draw a custom pendant outline, hatch a texture idea, or scribble a note exactly where it belongs on the piece. The sketch layer and the parts layer stay independently editable.

What is a jewelry spec sheet and why do I need one?

A spec sheet is the piece rendered alongside a list of its parts and dimensions — stone cut and size, setting type, band width, ring size, chain length. It is what a supplier needs to quote materials and what you need at the bench to build without re-deciding anything. Bezel exports one as a clean PDF or PNG.

Is there a jewelry design app for small makers who sell online?

Small makers are exactly who Bezel is built for. You can plan a piece on the couch, compare variations on a board, and export renders and spec sheets to plan listings and orders — all from a component library rather than from scratch each time.

How do I mark solder points on a jewelry design?

Use the Pencil annotation layer: draw an arrow or a dotted arc at the joint and label it. Because annotations sit on their own layer, they show up on the spec sheet as bench notes without altering the parts underneath.

Can I compare a silver and gold version of the same design?

Yes. Boards in Bezel keep variations of one design side by side — a silver band next to rose gold, an oval stone next to a round brilliant — so you can judge them together instead of flipping between files.

What ring sizes and units does a jewelry design app use?

Bezel supports both metric and imperial units, plus standard ring-size scales like US and UK, and chain lengths for necklaces. Dimension pickers are first-class in the app, so units are always visible — never an unlabeled number.

How big is a 1 carat stone in millimeters?

It depends on the cut: a round brilliant around 1 carat is roughly 6.4 to 6.5 mm across, while other cuts spread the weight differently. Bezel sizes stones in both mm and carats, so you can design with the measurement that matters for the setting.

What settings can a ring have — prong, bezel, halo?

A prong setting holds the stone with small claws for maximum light, a bezel wraps a metal rim around the stone for security, and a halo rings the center stone with smaller ones for spread. Bezel's component library includes these setting families as swappable, dimensioned parts, so you can try each on the same stone.

Can I design a necklace and get the right chain length?

Yes. Chains and clasps are library components with selectable lengths, and the canvas shows a live total-length readout as you compose. That makes it easy to plan whether a pendant sits at choker, princess, or matinee length before you cut anything.
