Problems we solve

Where diamond and jewellery businesses lose money

These are the leaks traders and manufacturers tell us about in every demo. Each one has a fix inside E-Ratna.

“Stones go out on memo and nobody chases them.”
Memo aging alertsEvery memo carries its due date, partial returns are reconciled line by line, and overdue stones are flagged before they become write-offs.
“One wrong Rap discount wipes out the margin on a parcel.”
Automatic Rapaport pricingBack-discounts, brokerage and FX are calculated on every buy, sell and memo line, from live RapNet prices.
“Our offices run in different currencies and the books never match.”
One multi-currency ledgerUSD, AED, HKD and THB settle in one double-entry system, with branch transfers and FX locked per deal.
“We know gold is lost at the workshop but can't prove where.”
Job bags and Tunch logsMetal is weighed out and back per karigar and process, with assay before and after melting, so every gram of loss has a name.
“After a trade show we spend days checking what came back.”
Booth barcode tallyScan the showcase and see missing, matched and conflicting stock in minutes, before you pack up.
“Certificates, specs and stock live in ten spreadsheets.”
4C engine with lab sync100+ parameters per stone, certificates validated with GIA, IGI and HRD, and feeds ready for buyers and B2B exchanges.

Buying questions

What buyers ask us before they switch

Moving your stock and accounts to a new system is a big decision. Here are straight answers to the questions we hear most.

You're based in India. Can you support us in Dubai, Hong Kong, Bangkok or New York?

Yes. E-Ratna is built and supported from India, and demo slots run in the morning for Dubai and Hong Kong and in the evening for New York. You talk to the same team that builds the product.

Can you move our data from spreadsheets or our current software?

Yes. We import your stock, parties and opening balances as part of onboarding, and we check the numbers with you before you go live.

Where is our data, and who can see it?

E-Ratna runs as a private cloud deployment. You can restrict access to your office IP addresses, set role-based permissions, and require a password to edit or delete past entries.

Does it work with RapNet, VDB and the grading labs?

Yes. RapNet pricing, VDB feeds and certificate sync with GIA, IGI and HRD are built in, not add-ons.

We trade natural and lab-grown stones. Can we keep them apart?

Yes. Natural, CVD and HPHT stock are kept in separate books, so they are never mixed in pricing or reports.

Is it a subscription?

No. E-Ratna is a one-time license. See the pricing section above in your own currency; the price depends on the edition, whether you add manufacturing, and whether you run one company or several.

Can it be changed to fit how we work?

Yes. E-Ratna is fully customisable: processes, reports and screens are adapted to your workflow during onboarding.
