Diamond sections cover rough planning and inclusion mapping, yield optimisation, assortment, the grading sequence through carat, colour, clarity and cut to laser inscription, cutting and polishing, and manual and machine setting.

Business sections cover manufacturing models from job work to own-brand, export-oriented and domestic units, mass production against artisan work, direct-to-consumer and white-label routes, plant setup with layout, utilities, effluent treatment and hazardous waste handling, machinery selection, production planning and quality control, capital investment and working capital, costing and pricing with making charges, wastage and recovery, break-even and profitability analysis, hallmarking and taxation compliance, and export documentation, pricing and support schemes.

Frequently Asked Questions

What does the Complete Technology Handbook on Jewellery Manufacturing cover?

The Complete Technology Handbook on Jewellery Manufacturing (EIRI, ISBN 9788199282759) covers the jewellery sector across nine parts. Its main divisions are: industry structure and market opportunity; business models and choice of segment and scale; metals, gemstones, diamonds and industry disclosure standards; design fundamentals and product development including computer-aided design; manufacturing processes from casting to finishing, with diamond jewellery treated separately; plant setup, machinery, production planning and quality control; capital investment, costing, pricing and profitability; regulatory compliance including hallmarking, taxation and export rules; and domestic and export marketing.

Who is this jewellery manufacturing handbook written for?

This handbook is written for readers running or starting a jewellery manufacturing business rather than for hobbyists. Its intended audience includes jewellery manufacturers and workshop owners, entrepreneurs entering precious, silver, lab-grown or artificial jewellery, designers moving into production, exporters and merchandisers, quality control and compliance staff, retailers considering own-brand manufacture, students of jewellery design and gemmology, technical libraries, and consultants preparing project or feasibility reports.

Who should consider starting a jewellery manufacturing business, and why?

Jewellery manufacture accommodates a wider range of entrants than most industries because scale is genuinely optional. A skilled bench jeweller can operate as a job worker for established brands with minimal capital, an entrepreneur can build an own-brand line through white-label or contract manufacturing without owning a workshop, and a well-capitalised operator can run a full casting-to-finishing plant. India's established clusters give access to skilled labour, machinery suppliers and component vendors that would be difficult to assemble elsewhere. Demand is supported by wedding and festival buying that is culturally embedded rather than discretionary, by gold's role as a savings instrument, and by growing fashion and lab-grown segments that need less capital than precious jewellery. The constraints are specific and financial rather than technical. Working capital is dominated by metal inventory, and gold price movement affects the balance sheet regardless of trading performance. Metal loss during casting, filing and polishing directly erodes margin, so recovery discipline matters more than it appears. Hallmarking is mandatory for gold jewellery sale in India with registration required. Trust and purity assurance determine whether customers return. And artificial and fashion jewellery, while cheaper to enter, competes on design turnover and volume against imports.

Does the book explain the jewellery manufacturing process step by step?

Yes. The production sequence is set out as a numbered process covering designing, computer-aided design and manufacture, model making, rubber mould preparation, waxing and wax tree assembly, casting, grinding, filing with assembly and pre-polishing, metal setting, polishing, rhodium plating, quality control, hallmarking and certification. Casting content covers the burn-out cycle, centrifugal and vacuum casting and precious metal casting practice. Stone setting content covers prong, bead, pave, bezel, semi-bezel, gypsy, channel, flush and milgrain settings individually, along with manual and machine setting methods. Finishing content covers electroplating principles and techniques, coating processes, surface finishes and textures.

What does the book cover on lab-grown diamonds?

Lab-grown diamonds are covered as a distinct production and commercial category. Content includes the two main production methods, high pressure high temperature and chemical vapour deposition, with their process descriptions, the structural variances and growth patterns that distinguish grown from natural stones, demand for custom shapes, and a comparison of manufacturing and production differences between natural and lab-grown. Planning content covers inclusion mapping, advanced scanning, smart planning algorithms and yield maximisation. Disclosure content is treated separately and covers labelling requirements for natural, treated, lab-grown and simulated stones, the terminology permitted, symbols for enhancement disclosure, and the international trade body standards and consumer protection guidelines that govern how each must be described.

What are the compliance requirements for jewellery manufacture in India?

The book covers hallmarking, taxation and export compliance. Hallmarking content covers the BIS mark, purity expressed in karat and fineness, the assaying centre mark and jeweller identification mark, certificate types, registration procedure and documents required for both jeweller showrooms and assaying and hallmarking centres. Taxation content covers goods and services tax treatment across gold purchase, ready-made ornaments, bars and coins, second-hand gold, making charges, custom-made jewellery, repairs, reverse charge and various gold investment instruments. Export content covers licensing and registration, customs compliance, certification, anti-money laundering and counter-terrorist financing obligations, duties and ethical sourcing standards. Readers should verify current hallmarking scope, tax rates and export rules with the relevant authority, as all three have changed in recent years.

Does the book cover costing, pricing and profitability?

Yes, and this is one of its stronger sections for anyone running a unit. Costing content covers the full pricing formula and a simplified version, precious metal cost, wastage and recovery, making charge structures and labour cost models, the factors influencing pricing, a typical cost breakdown, stone and component cost management, and separate domestic and export pricing strategies. Financial content covers income and expenditure statements, profit margin norms and the factors affecting them, expenditure categories, break-even analysis with formulas and worked calculation, profitability ratios and operational benchmarks, key performance indicators, and sensitivity and risk analysis with mitigation strategies. Capital investment content covers land, building, infrastructure, machinery, working capital estimation and sources of finance including eligibility for small enterprise credit.

Does the book cover plant setup and machinery selection?

Yes. Setup content covers site selection factors with a checklist and ideal location types, plant layout with core components and the differences between precious and artificial jewellery layouts, utilities and power requirements, safety protocols, compliance obligations, and environmental management including effluent treatment plant setup, hazardous waste and chemical handling and air pollution control. Machinery content covers melting and casting, forming and shaping, stone setting, finishing and polishing equipment across gold, silver and artificial jewellery, computer-aided design and prototyping equipment, plating and coating equipment, diamond processing machinery, and supplier information. Operations content covers production planning stages, inspection protocols, quality management systems and metrics, loss control, rejection management and inventory tracking technologies.
