The Comprehensive Guide to Gold Jewelry Valuation & Traditional Units
Master the mathematics of Vori, Anna, Roti, Karat purity ratings, making charges, sales tax (VAT), and gold price calculation.
Understanding Gold Valuation & Retail Receipts
Calculating the retail price of physical gold jewelry requires combining raw material spot pricing with manufacturing charges and government sales tax. Unlike standardized financial bullion (which trades purely at melt value), consumer jewelry receipts breakdown into three distinct financial components:
Traditional South Asian Gold Weight Units: Vori, Anna, Roti & Point
In South Asian and Middle Eastern gold trading, weights are traditionally quoted in Vori (or Tola), Anna, Roti, and Point:
- 1 Vori (Tola): Equals exactly 16 Annas or 11.664 Grams.
- 1 Anna: Equals exactly 6 Rotis (or 0.729 Grams).
- 1 Roti (Night): Equals exactly 10 Points (or 0.1215 Grams).
- 1 Point: Equals 0.01215 Grams.
Karat Purity Ratings & Fineness
Gold purity is measured in 24ths (Karats) or parts per thousand (Fineness):
đ 22 Karat (91.6% Pure / 916 Fineness)
The international gold standard for bridal necklaces, bangles, and heavy ornaments. Alloyed with 8.4% copper/silver for strength.
đ 18 Karat (75.0% Pure / 750 Fineness)
Highly durable alloy used for diamond settings, engagement rings, and luxury watches.
