Dual-Unit Mass Balance: The Definitive Guide to Gross Weight, Net Alloy, and Carat Accounting

Solving complex jewelry bookkeeping: tracking separate ledger accounts for precious metal mass, stone carat deductions, and making charges.


Why Standard ERPs Fail at Jewelry Bookkeeping

Standard enterprise accounting software (SAP, Oracle, NetSuite) is engineered for single-unit mass or discrete piece counts. In fine jewelry, every item possesses three distinct dimensions of value: Gross Mass (total scale weight in grams), Stone Weight (deducted carats converted to grams at 1ct = 0.20g), and Net Precious Metal Mass (pure gold/silver content).

CaratOS was built from the ground up to solve dual-unit mass accounting natively.

The Immutable Three-Tier Mass Ledger

Whenever an item moves through manufacturing, valuation, or sale, CaratOS maintains continuous balancing across all three tiers, ensuring zero discrepancy between the physical balance scale and the general ledger balance sheet.

Automated Hallmarking & Certificate Linkage

Every mass balance transaction is cryptographically linked to the item's BIS Hallmarking HUID code and IGI/GIA certificate serial number.
