The three inputs that determine gold melt value
1. Verified gold-only weight
Use grams, pennyweight or troy ounces consistently. One troy ounce equals approximately 31.1035 grams. Stones, watch movements, steel springs and other non-gold parts should not be counted as gold weight.
2. Verified purity
Convert karat to purity by dividing by 24. Hallmarks can help identify an expected purity, but high-value or uncertain items should be professionally tested.
3. A current fine-gold reference price
International gold is commonly quoted per fine troy ounce. Convert it to a per-gram price before multiplying by fine-gold grams. Use prices recorded at the same time when comparing offers.
The gold value formula
Keep the weight and gold-price units the same throughout the calculation.
Suppose a 14K item has a verified gold-only weight of 10 grams. Its estimated fine-gold content is 10 × 0.5833, or approximately 5.833 grams. Multiply that figure by the current fine-gold price per gram.
Calculate with the live gold price →Melt value, resale value and buyer offer are different
Raw gold content
The fine-metal value before commercial deductions.
The intact item
May include brand, design, stones, condition or collector interest.
The net amount
What a particular buyer will pay after its testing, costs and margin.
A generic or damaged item may trade mainly on melt value. A signed vintage piece, an intact watch or a collectible coin may be worth more in its existing form. Obtain a specialist assessment before scrapping anything that may have secondary-market demand.
Why calculated value and an offer may differ
- Net weight: stones and non-gold components may be excluded.
- Assay uncertainty: solder and mixed parts can produce different purities.
- Refining: small, mixed or contaminated lots can cost more to process.
- Price timing: gold can move between calculation and settlement.
- Business costs: insurance, security, labour and margin affect offers.
- Collectability: a melt-only quote ignores design or collector value.
The important question is not whether every deduction exists. It is whether the buyer clearly explains the tested purity, accepted weight, reference price, deductions and net payment.
Worked valuation examples
| Item | Gross weight | Purity | Fine gold | What to verify |
|---|---|---|---|---|
| 14K ring | 10 g | 58.33% | 5.833 g | Stones and sizing material |
| 18K chain | 20 g | 75% | 15.000 g | Clasp and solder |
| 22K jewellery | 15 g | 91.67% | 13.750 g | Actual assay and attachments |
These examples show theoretical fine-gold content. They are not offers and assume that the entire stated weight is the stated alloy.
What to do before requesting buyer offers
- List each item separately with its weight and visible marks.
- Calculate an independent melt-value reference.
- Identify items that may have resale or collector value.
- Ask each buyer how purity and net gold weight will be tested.
- Request the final payment after every fee and deduction.
- Compare all offers against the same timestamped gold price.

COMMON QUESTIONS
How Much Is My Gold Worth? A Practical Valuation Guide: FAQ
Is melt value the amount a gold buyer will pay?
Not necessarily. Melt value is the fine-metal reference before a buyer accounts for testing, refining, operating costs, risk and margin.
How much is a 14K gold ring worth?
Start with the ring's gold-only weight. Multiply that weight by 58.3% and by the current fine-gold price per gram. Stones, non-gold components and buyer deductions must be considered separately.
Can old jewellery be worth more than scrap value?
Yes. Recognised makers, desirable designs, gemstones, provenance and collectability can make an intact item worth more than its raw gold content.
Should I remove stones before weighing gold?
Do not damage a valuable item. Ask a qualified jeweller or buyer to provide the net gold weight and explain how stones and non-gold parts were handled.
