Questions about
Short answers about memo, lab-grown stock, gold loss, yield, currencies and editions.
What is diamond memo (consignment) software?
Memo software tracks stones and jewellery you send to, or receive from, another business on consignment before a sale is final. In E-Ratna every memo line carries its party, weight, price and due date; partial returns are reconciled line by line, and overdue memos are flagged automatically.
Does E-Ratna keep natural and lab-grown diamonds separate?
Yes. Natural, CVD and HPHT stones are kept in separate books, so they are never mixed in pricing, stock reports or certificates.
How does E-Ratna measure gold loss at the karigar or casting stage?
Each job bag records the gross weight and purity (Tunch) of metal issued and returned. E-Ratna converts both to fine gold and reports the fine loss in grams and as a percentage per karigar and per process, against the tolerance you set.
What is Kapan yield and how is it tracked?
Kapan yield is the polished carats recovered from a rough parcel, as a percentage of rough carats. E-Ratna tracks rough issued to polishers, polished carats returned, loss per worker and process, and the profit of each Kapan in real time.
Which currencies and integrations does E-Ratna support?
E-Ratna settles in USD, AED, HKD, THB and INR in one double-entry ledger, with FX locked per deal. It integrates with RapNet pricing, VDB feeds and certificate data from GIA, IGI and HRD.
What is the difference between the Trading and the Trading + Manufacturing editions?
The Trading edition covers purchase, sales, memo, diamond inventory, accounts and reports. Trading + Manufacturing adds jobwork, karigar job bags, Tunch and melting loss, rough-to-polish processing, Kapan yield and production costing.
