How to Calculate the Value of Old Gold

Published 04 Oct 2026

Before you sell, it helps to know roughly what your old gold is worth. You only need three numbers.

Step 1: Find the net weight

Weigh the jewellery (the gross weight). Then subtract anything that is not gold — stones, beads, lac or wax filling, threads. What is left is the net weight.

Step 2: Find the purity

Use the karat stamp as a starting point:

  • 24K ≈ 0.999
  • 22K = 0.916
  • 18K = 0.75

The final purity comes from the test done when you sell. Old or repaired jewellery is often a little lower than the stamp.

Step 3: Multiply by today's 24K rate

Fine gold (g) = net weight × purity
Value = fine gold × today's 24K rate per gram

Check the gold rate in Kadapa today before you calculate.

Examples (using an example rate of ₹10,000/g)

A 22K necklace, 30 g gross, 2 g stones

  • Net weight = 28 g
  • Fine gold = 28 × 0.916 = 25.648 g
  • Value = 25.648 × ₹10,000 = ₹2,56,480

An 18K ring, 5 g, no stones

  • Fine gold = 5 × 0.75 = 3.75 g
  • Value = 3.75 × ₹10,000 = ₹37,500

Deductions to ask about

  • A service charge (if any) — it should be shown clearly before you agree.
  • The buying rate may be slightly below the live market rate.
  • Making charges and GST paid when you bought the jewellery are not returned.
