Every day you waste 10, 15, 20 minutes hunting through charts, converting between ring size systems, working out alloy ratios on scraps of paper, and Googling metal prices on your phone with polishing compound on your fingers.
That’s 5+ hours a month you could be setting stones, finishing pieces, or going home early. At $75/hour, that’s $375/month in lost bench time.
Device-calibrated circles & finger bands. UK, US, EU, JP, Swiss systems. Accurate to 0.02mm.
20+ alloys. Enter dimensions, get weight instantly. Gold, silver, platinum, palladium, steel, titanium.
11 diamond shapes, 24 gemstones, 58-row mm-to-carat chart. Quick bur guide included.
12 standard recipes. Mix from fine, mix for total weight, or convert between karats. No more scrap paper.
Gold, silver, platinum, palladium — updated in real time on your home screen.
Casting weight, ring blank, ring sizing, pavé counter, eternity planner, prong guide, bezel wall, rhodium plating.

We’re looking for working bench jewellers to beta test BenchCalc before launch. You’ll get free early access, a direct line to shape what gets built, and a lifetime launch discount. Spots are limited — we need real feedback from real jewellers.
BenchCalc is built by Ian Barnard, a master jeweller specialising in micro diamond setting. After a decade at the bench reaching for charts, converting sizes in his head, and Googling the same formulas over and over, he decided to build the app every bench jeweller actually needs.
This isn’t a generic calculator with a gold skin. Every feature is designed by someone who actually uses it, for people who actually need it.
