But what if your necklace weighs 20 grams and the buyer calculates its value using only 18 grams? This can be confusing, especially if you are selling gold for the first time. The reason is simple. Your jewellery may contain stones, beads, or other materials that are not gold. Understanding how gold valuation works can help you know its value and make a better decision.
1. What Is Gross Weight and Net Gold Weight in Jewellery?
During gold valuation, you may hear two terms: gross weight and net gold weight.
Gross weight is the total weight of your jewellery, including gold, stones, and other materials.
Net gold weight is the weight of the gold alloy after excluding non-gold materials.
For example, consider a gold necklace weighing 20 grams.
- Total necklace weight: 20 grams
- Stones and other materials: 2 grams
- Net gold alloy weight: 18 grams
The buyer may calculate its value using 18 grams instead of 20 grams.
Your jewellery has not lost weight. The buyer is simply calculating the gold alloy weight separately.
2. Why Do Gold Buyers Deduct the Weight of Stones?
Many gold ornaments contain materials other than gold.
A ring may have a gemstone, while a necklace may contain colourful stones or decorative beads.
These materials add weight but are not part of the gold.
Gold buyers may exclude:
- Gemstones and artificial stones
- Decorative beads
- Enamel and non-gold materials
- Threads and attachments
- Other non-gold decorative parts
For example, an 8-gram ring with a 1-gram stone may contain approximately 7 grams of gold alloy.
Understanding these deductions helps explain why the net gold weight may be lower than the total weight.
3. Does Gold Purity Affect Your Jewellery’s Weight?
Gold purity affects the amount of pure gold in your jewellery, but it does not change its physical weight.
Most gold jewellery contains other metals to make it stronger.
Common purity levels include:
- 24K: Approximately 99.9% pure gold
- 22K: Approximately 91.6% pure gold
- 18K: 75% pure gold
- 14K: Approximately 58.5% pure gold
For example, 10 grams of 22K gold alloy contains approximately 9.16 grams of pure gold.
The ornament still weighs 10 grams. Its purity tells you how much of that weight is gold.
Both weight and purity matter when you sell gold in Bangalore.
4. Can Jewellery Design Affect Gold Weight?
Yes. Jewellery design can affect the amount of gold present.
A plain chain and a stone-studded necklace may both weigh 25 grams. However, the necklace may contain less gold because of its stones and decorative materials.
Some jewellery may contain:
- Wax or lac filling
- Hollow sections
- Non-gold supporting materials
- Decorative fittings
These materials may not be visible from the outside.
A proper valuation helps identify the estimated gold alloy weight.
5. How Does German XRF Technology Check Gold Purity?
Gold purity testing is an important part of jewellery valuation.
At G1 Gold Company, we use German XRF Technology for Gold Purity Testing to check the purity of gold jewellery.
XRF stands for X-ray Fluorescence. It uses X-rays to analyse the metal composition near the jewellery’s surface.
Benefits of XRF testing include:
- Non-destructive testing: Normally does not require cutting or melting jewellery.
- Quick results: Checks the metal composition within a short time.
- Purity information: Helps identify the gold content in the tested area.
- Clear results: Helps customers understand their jewellery’s purity.
XRF testing measures the surface composition. Gold plating, solder, or different metals in your jewellery can affect the test results. Sometimes, more tests may be needed to check the purity accurately.
6. How Do Gold Buyers Calculate Your Jewellery’s Selling Price?
Gold buyers generally calculate the price using:
- Net gold alloy weight
- Gold purity
- Applicable gold buying rate
- Any disclosed charges or deductions
For example:
Suppose your jewellery has:
- Net gold alloy weight: 15 grams
- Purity: 22K
- Example 22K buying rate: ₹12,000 per gram
Estimated value = 15 × ₹12,000 = ₹1,80,000
This is only an example, not a current gold rate or confirmed buying offer.
The final amount may vary depending on testing results and the buyer’s pricing terms.
Always ask how the final price is calculated.
7. What Should You Check Before Selling Your Gold?
Before selling your jewellery, take a few minutes to understand the valuation.
Follow these simple steps:
- Check the weight: Ask to see your jewellery being weighed.
- Understand deductions: Check whether stones or other materials affect the weight.
- Check purity: Ask how your gold’s purity is tested.
- Know the rate: Confirm the gold buying rate.
- Review the offer: Understand the final price and any charges.
At G1 Gold Company, we show you how your gold is checked and weighed. We also explain the price clearly before you decide to sell.
Knowing these details can help you make an informed decision.

3. Is German XRF Technology safe for gold jewellery?
Yes. XRF testing checks your gold’s purity without normally cutting, melting, or damaging your jewellery.
4. Does 22K gold contain less pure gold than 24K gold?

5. Where can I check my gold jewellery’s purity in Bangalore?
Choose a trusted gold buyer who checks your gold’s purity and clearly explains its value. Always check the weight, purity, and price before selling.
Conclusion
Your jewellery does not actually lose weight during valuation. The difference comes from removing the weight of stones, beads, and other materials that are not gold. Gold purity also affects the final selling price.
