Why Stone Weight Reduces Your Gold Value - And How Buyers Calculate It
When you sell your gold jewellery, the final price often turns out lower than expected — and one common reason is the stone weight deduction.
Most jewellery pieces contain stones, pearls, American diamonds, glass pieces, enamel, or other non-gold materials. Since these do not hold resale value, jewellers remove their weight before calculating your gold’s price.
At True Gold Company, we believe in complete transparency. Here’s a clear explanation of why stone weight matters, how jewellers calculate it, and how to avoid losing value.
What Is Stone Weight?
Stone weight refers to anything in your jewellery that is not gold:
CZ stones (American diamonds)
Precious stones (ruby, emerald, sapphire, etc.)
Polki/Kundan work
Beads or pearls
Meena (enamel)
Glass pieces
Lac, wax, or supporting material inside bangles
These materials add weight to the jewellery – but do not add value when you sell it.
Why Does Stone Weight Reduce Your Gold Value?
Gold buyers pay ONLY for the net gold weight.
Even if your jewellery looks heavy, a portion of that weight comes from stones.
If buyers paid for the stones, you’d be getting extra money for materials that aren’t gold.
So, the higher the stone content, the lower your gold value.
How Jewellers Calculate Net Gold Weight
Here’s the simple formula:
Net Gold Weight = Total Weight – Stone Weight
Example:
Total jewellery weight: 20 grams
Stone weight: 5 grams
➡️ Net gold weight = 15 grams
Only these 15 grams are considered for pricing.
How Do Buyers Identify Stone Weight?
Professional buyers like True Gold Company use:
✔ Digital Karat Meters (XRF Machines)
These machines scan the jewellery and identify:
Purity (e.g., 22K, 20K, 18K)
Non-gold elements inside the item
✔ Precise Stone Removal Checks
Some items have removable stones; others require estimation using:
Density
Laser scanning
Shape and setting type
✔ Experience-Based Judgement
Traditional Kundan or heavy-stone bangles have predictable stone-to-gold ratios.
How Stone-Heavy Designs Affect Gold Value
1. Kundan / Polki Jewellery
Very beautiful but contains lots of lac and stones.
Actual gold content can be much lower.
2. Gemstone Studded Rings
A large stone on a ring reduces gold weight significantly.
3. Heavy Bridal Sets
Many contain imitation stones, lowering the net gold weight drastically.
Purity Also Matters
After determining net gold weight, buyers check purity.
Final Value = Net Gold Weight × Purity × Today’s Gold Rate
Example:
Net weight = 15g
Purity = 22K (91.6%)
Rate = ₹6,000/g
Value = 15 × 0.916 × 6000
Value = ₹82,440
This is how transparent buyers calculate your amount.
