Ring sizing, metal weights, alloy mixing, stone charts, live prices. One app, zero guesswork. Built by a master jeweller, for jewellers.
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.

Built to simplify your daily workflow through intelligent, purpose-built tools that understand the jeweller's bench.
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.
Device-calibrated circles & finger bands. UK, US, EU, JP, Swiss. All four systems. Accurate to 0.02mm.
CAD volume, wax, sheet metal, bullion. All instantly convertible to any metal or karat. 20+ alloys covered.
11 shapes, full mm-to-carat charts for round and fancy cuts. Look up any size in seconds.
Tell it your target karat and total weight. It calculates exactly how much of each component you need.
Gold, silver, platinum, palladium. Updated in real time on your home screen.
Count stones across all 11 shapes, get total carat weight, then build and export a full job quote.
Fit stones around a ring with correct spacing, then map out your exact layout visually before you touch a tool.
Gauge to MM, alloy specs, saw blade sizes, solders and temperatures. Always in your pocket.
Materials, labour, markup. Get your sale price and profit margin instantly. Never undercharge again.

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.
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.
