Diamond Manufacturing Software: What to Track from Rough to Polished

Diamond manufacturing software should follow every stone from the rough kapan to the polished, certified diamond and answer four questions at any moment: where is it, who has it, what did it weigh at the last handover, and what is owed for the work done on it. If the software records those four things at every stage, the reports owners actually want (yield per kapan, weight loss by karigar, payroll and polished stock) come out of the same data.

This guide walks through what to track at each stage in a Surat manufacturing unit, how issue and receive should work, and when a ready-made package is enough and when a custom system earns its cost.

Why accounting software isn't enough on the factory floor

Tally and other accounting tools track money: purchases, sales, payments and GST. A manufacturing unit also has to track stones, and stones change. One rough becomes two polished stones, a piece breaks, the weight drops at every wheel, and each stage is done by a different person on a different rate. Most units handle this with department registers, packet slips and Excel sheets that someone reconciles at the end of the week. That works until volume grows, a packet goes missing, or the weight loss on a kapan is far above plan and nobody can say at which stage it happened.

The stages to track

Every unit names and orders its processes a little differently, but most follow a path close to this one. The table shows what each stage should record.

Issue and receive: the entry everything rests on

Every handover between people or departments should be two entries: an issue and a receive. The person issuing records the packet, pieces and weight, and the person receiving confirms them. When the work comes back, the same happens in reverse with the new weight. That gives you:

• A full history of every packet, with who held it and for how long.

• Weight loss per stage and per karigar, calculated by the system instead of on a calculator.

• Pending work: which packets are with which department right now, and for how many days.

• A clear point of responsibility when pieces or weight don't match.

Barcode or QR labels on packets make this quick enough for a busy floor: scan, check the weight, confirm. Where the electronic scale supports a data connection, the weight can be read straight into the system instead of typed, which removes a common source of mistakes.

Setting limits for weight loss

Expected weight loss differs by stage, shape and size. Store the expected range for each and let the system flag any receive that falls outside it. A flag is a prompt to check the stone while the packet is still on the desk, rather than three weeks later when the kapan report comes out.

Karigar piece rates and payroll

Most polishing work in Surat is paid by the piece, with rates that change by stage, size range and shape. When the rates live in the software, payroll for each karigar becomes a report: pieces received, the rate for each, and adjustments under your unit's rules for rejects, advances and deductions. The weekly or fortnightly payment sheet stops being a weekend of manual totals, and each karigar can see a clear breakdown of what they've been paid for.

Yield and costing per kapan

The question every owner asks is whether a kapan made money. To answer it, the system needs:

• Rough cost per carat and total cost for the kapan.

• Planned polished output from the scan and the chosen plan.

• Actual polished output, stone by stone, after final assortment.

• Labour cost from piece-rate payroll, plus certification and other direct charges.

• A value for the polished goods, from your own price list or a reference list such as RapNet if you subscribe to one.

Put together, that shows planned against actual yield and value for each kapan, each rough supplier and each assortment. Over a few months it tells you which rough purchases and which plans work best for your unit.

Polished stock, certificates and memo

Once a stone is polished, the software becomes a stock system. Each stone needs its own record: weight, shape, colour, clarity, cut grades, measurements, the lab and report number, and a status such as in office, at the lab, out on memo or sold. Memo and consignment are where stock most often goes missing on paper, so record every memo with the broker or buyer, date, stones and expected return date, and keep overdue memos on the dashboard. Our page on diamond inventory management software in Surat covers this side in detail. If you sell to trade buyers online, a B2B diamond trading portal can read from the same stock, and our diamond and jewellery website guide explains what buyers expect to see.

Lab-grown diamonds: same stages, different pressures

Laboratory-grown rough, whether CVD or HPHT, is cut and polished on the same kind of wheels by the same kind of karigars, so the stage tracking above applies as it is. The differences are in the business around it: prices move faster, volumes are often higher, and natural and lab-grown stock must never mix. Keep them as separate stock types from the rough stage onwards, label them on every packet and every report, and use separate price lists. Units that grow as well as cut also need to track growth runs and as-grown output. See lab-grown diamond software in Surat.

Details that decide whether the floor uses it

• Gujarati on the floor. Screens for department managers and karigars should be available in Gujarati, with English for reports and buyers.

• Tablets at each department. Issue and receive at the desk where the work happens beats one computer in the office.

• Roles. A department manager sees their department, the accountant sees costs and payroll, and the owner sees everything.

• Patchy internet. Plan for it, either with a local server or entries that sync when the connection comes back.

• Tally export. Purchases, sales and payroll totals can flow to Tally so your CA keeps working as before.

Ready-made package or custom build?

Several ready-made diamond manufacturing packages are sold in Surat, and for a unit whose process matches the package, one of them is a quick and sensible start. Custom software makes sense when:

• Your process, stage names or rate rules differ from what the package expects, and staff keep side registers to cover the gap.

• You want manufacturing, polished stock, memo, a buyer portal and accounting exports to work as one system.

• You want reports in the exact form you use to decide on rough purchases.

• You want to own the code and the data, and change the system as the unit changes.

A practical way in is to start with issue and receive plus weight loss for one department, then add payroll, kapan costing and polished stock once the floor is using it every day. Our general post on custom software vs off-the-shelf covers the wider trade-off.

How MOMT builds diamond software

We are a Surat team, founded in 2018, building custom web and mobile software with React, Next.js, Node.js and PostgreSQL or MongoDB. We have built an order production and dispatch tracking system and an inventory system with picklists, and both share the core of packet tracking: every item has a status, a holder and a history. You get a fixed quote after a short call, weekly demos on a live preview link, the code is yours, and every build has a 30-day warranty after launch. Our listed plans start at ₹1.5 lakh for custom builds; you get a fixed quote for your scope. Read more on diamond manufacturing software in Surat and diamond ERP software development.

Frequently Asked Questions

Can the software work with Sarine or Galaxy scan files?

It can store the scan file and plan reference against each stone. Reading plan data directly from the files depends on the export formats your equipment provides, which we check during scoping.

Can we bring in our existing Excel data?

Yes. Open packets, polished stock, karigar lists and rate cards can be imported from Excel so you start with today's position rather than a blank system.

How long does it take?

A first module such as issue and receive with weight loss can usually be in use within 3–6 weeks, depending on scope. Payroll, costing and polished stock follow in stages.

Can the owner see it on a phone?

Yes. The system runs in a browser, so pending packets, weight-loss flags, memo status and stock can be checked from a phone, and a React Native app can be added if you want one.
