CaratLedger
Diamond & Jewellery Management Software
Rough to polished, karigar to certificate — tracked by carat.
The problem
Why this gets built
Value in this trade is measured in fractions of a carat, and it moves through many hands before it comes back. Without lot-level tracking, yield is an estimate, karigar accounts are settled from memory, and a shortfall is discovered long after the parcel has moved on.
Who it is for
Fit
Diamond polishing and jewellery manufacturing units in Surat and Mumbai running job work at scale.
Capabilities
What the system does.
Rough lot tracking
Every lot and packet recorded from purchase, with weight and cost carried through every process.
Yield analysis
Rough carats in against polished carats out, per lot and per karigar, so yield is measured rather than assumed.
Karigar job work
Issue and receipt against each worker with labour rates per carat and outstanding parcels visible at all times.
Assortment & grading
Polished stock organised by the 4Cs, with assortment recorded as it happens.
Certification
GIA and IGI certificate numbers tied to stones, so a certificate is never separated from what it certifies.
Party ledgers
Purchase, sale and memo movement per party with outstanding positions current, not month-end.

Questions
Common questions.
How is yield calculated?
Rough carats issued are measured against polished carats received, per lot and per karigar, so yield is a recorded figure rather than an estimate.
Can it track karigar job work?
Yes. Every issue and receipt is recorded against the worker with labour rates per carat, and outstanding parcels are visible at any moment.
Does it store certification details?
Yes. GIA and IGI certificate numbers are tied to the stones they certify, so a certificate is never separated from its stone.
