How It Works

• Enter the total ring weight in grams.
• Enter the total gemstone weight in carats.
• The tool subtracts 0.2 grams per carat to estimate the gemstone weight.
• The result is your estimated net gold weight.

Example

If your ring weighs 5.80 grams and has 1.20 carats of diamonds:

Net gold weight = 5.80 − (1.20 × 0.2) = 5.56 grams

Why Use This Tool?

It’s ideal for jewelers, resellers, or curious buyers who want a quick estimate of the real gold weight in a piece of jewelry.

Note: This calculator gives an approximate value based on an estimated 0.2g per carat. For precise results, consult a professional appraiser.
