Bench Reference — The Professional Jeweler's Pocket Guide
Everything a bench jeweler needs, right on your phone. Bench Reference puts 30+ reference sections, professional calculators, and a personal library system in your pocket — no internet required.
GEMSTONES & MATERIALS
Browse 100+ gemstones with Mohs hardness, specific gravity, refractive index, care instructions, setting tips, steam safety, and cleaning methods. Filter by hardness or steam safety to make quick decisions at the bench. Plus dedicated sections for pearls, birthstones, gemstone origins, and stone shapes.
BENCH TECHNIQUES
Step-by-step reference guides for stone setting (prong, bezel, pavé, channel, flush, tension), soldering, casting, polishing, engraving, wax carving, repairs, annealing, torch & gas, laser welding, rhodium plating, patina & oxidation, and chemical safety. Each section built from real bench experience.
23 METALS
Melting points, annealing temps, hardness, specific gravity, and working notes for every metal you'll encounter — from 24K gold and platinum to palladium, steel, and titanium.
REPAIRS HUB
Sizing up, sizing down, shank replacement, prong rebuilding, chain repair, clasp replacement, soldering guides, porosity troubleshooting, and more. A complete repair reference when you're at the bench.
MEASUREMENTS & DATA
Ring sizes (US/UK/EU with conversions), wire gauge reference, MM-to-carat weight charts by stone shape, chain styles, necklace and bracelet lengths, finding sizes, and formulas for weight, pricing, and alloy calculations.
IDENTIFICATION & TESTING
Gemstone testing methods, acid testing procedures for gold, silver, and platinum, hallmark identification, metal allergy reference, and a Stone ID table with SG and RI values for quick identification.
PROFESSIONAL TOOLS
Ring Blank Calculator — stock length for any ring size
Metal Weight Calculator — weight by dimensions and alloy
Job Pricing Calculator — materials, labor, and markup
Temperature Converter — Fahrenheit and Celsius
Weight Converter — grams, dwt, troy oz, carats
Bench Timer — burnout and casting countdowns
3D PRINT & CAD
Castable resin profiles, resin comparison charts, shrinkage calculator, burnout schedules, support placement guide, troubleshooting, post-processing, printer settings, and stone-in-place casting. Plus MatrixGold CAD shortcuts and workflows.
