Stop Googling.
Start Calculating.

Every calculation a bench jeweller makes: ring sizing, metal weights, alloy mixing, stone charts, live prices. One app.

You're losing 5 to 10 minutes a day on calculations you've done a thousand times. That's an hour a week back at the bench doing actual work.

The Problem

You’re a jeweller,
not a mathematician

Every day at the bench you're hunting through charts, converting ring sizes in your head, working out alloy ratios on scrap paper, and Googling metal prices with polishing compound on your fingers.

That’s 10, 15, 20 minutes a day. Every single day. Small interruptions that break your focus, slow your workflow, and add up to a serious chunk of your week.

BenchCalc puts every answer in your pocket in seconds. Get back to the work that actually moves the needle.

Limited Spots,Beta Testing

Want to test it before anyone else?

We’re looking for working bench jewellers to put BenchCalc through its paces before launch. You’ll get free early access, a direct line to shape what gets built next, and a lifetime discount locked in at launch. Spots are limited,we need real feedback from people who actually use these tools every day.

Not a tech company.

BenchCalc is built by Ian Barnard, a master jeweller specialising in micro diamond setting. After years at the bench reaching for charts, converting sizes in his head, and Googling the same formulas over and over, he decided to build the tool every bench jeweller actually needs.

This isn’t a generic calculator dressed up in gold. Every feature exists because someone who works at a bench every day needed it.
