Quick answer: The quantity of gold required to make an ornament is its finished net metal weight plus the gold lost while making it. Actual loss is small: India's DGFT allows 0.90% for machine-made and 2.25% for handcrafted plain gold jewellery. A 22K ornament of 10 g needs about 10.1–10.2 g of 22K metal, of which 91.6% is pure gold.
What does "quantity of gold required" mean for an ornament?
It means the weight of gold alloy a goldsmith must put in to get the finished piece. That has three parts:
Net weight of the finished ornament. This is the gold metal left in the piece, without stones, beads or threads.
Process loss. Gold lost as dust, filings and polish residue while melting, casting, soldering and finishing. Workshops recover much of it.
Alloy share. Jewellery is not pure gold. A 22K ornament is 91.6% gold and 8.4% other metals such as copper and silver.
So the honest answer has two numbers. One is the metal weight that goes in. The other is the pure gold inside the finished piece.
Key facts at a glance
Typical Indian ornaments use from about 2 g (a pair of studs) to 100 g or more (a bridal haram).
Real manufacturing loss is about 1–2.5% of the metal for plain jewellery and up to about 4% for studded work. DGFT's export norms set 0.90% for mechanised and 2.25% for handcrafted plain jewellery.
The "wastage" or "VA" on a retail bill is a charge, not a measured loss. CaratLane's manufacturing head put traditional jewellers' wastage charges at 3% to 35%.
Pure gold content depends on karat: 91.6% in 22K, 75% in 18K and 58.5% in 14K, per BIS purity grades.
You pay the gold rate on net weight. Stones and beads should be weighed and priced separately.
How much gold is used in common ornaments?
The table gives indicative finished weights for 22K pieces in India, based on BlueStone's 2025–2026 weight guides. The last column shows the pure gold inside, at 91.6%.
Ornament | Typical finished weight (22K) | Pure gold inside |
Pendant | 2–6 g | 1.83–5.50 g |
Stud earrings (pair) | 2–4 g | 1.83–3.66 g |
Ring | 3–6 g | 2.75–5.50 g |
Jhumka / drop earrings (pair) | 5–12 g | 4.58–10.99 g |
Chain | 8–20 g | 7.33–18.32 g |
Mangalsutra | 4–40 g | 3.66–36.64 g |
Bangle (single) | 15–25 g | 13.74–22.90 g |
Necklace | 20–60 g | 18.32–54.96 g |
Haram / long bridal necklace | 40–100+ g | 36.64–91.60+ g |
Stud, jhumka and haram bands are our own estimates; the others follow BlueStone's guides. Design, hollow vs solid construction and size can move any piece outside these bands.

What is the difference between gross weight and net weight?
Gross weight is everything on the scale: gold, stones, beads, enamel, wax fill and thread. Net weight is the gold metal alone. Gold is charged at the gold rate only on net weight.
This matters most for stone-set pieces, mangalsutras with black beads, and kundan or polki work. CaratLane has warned that some jewellers charge the gold rate on the full weight, then deduct stone weight at exchange. If stones make up 10% of the weight, you overpay by about that much.
Example: a 22K necklace weighs 32 g gross, with 4 g of stones. At ₹13,085/g (Groww, 26 Oct 2026):
Basis | Weight | Gold value |
Gross (wrong basis for gold) | 32 g | ₹4,18,720 |
Net (correct basis) | 28 g | ₹3,66,380 |
Difference | 4 g | ₹52,340 |
Always ask for both weights on the tag and the invoice. The stones should appear as a separate line.
How much gold is lost while making an ornament?
Some gold is always lost to the workbench. It goes as filings, sprue offcuts, polishing dust and tiny amounts lost in melting. Goldsmiths sweep, filter and refine this material, so most of it is recovered over time.
The most specific official benchmark is the Directorate General of Foreign Trade's wastage norm for export jewellery. DGFT Public Notice 45/2024-25 (4 Feb 2025) sets these allowances for plain gold jewellery:
Method | Allowed loss (DGFT) | Gold needed for 10 g finished |
Mechanised (machine-made) | 0.90% | about 10.09 g |
Handcrafted | 2.25% | about 10.23 g |
Studded, mechanised (SION input norm) | 2.8% | about 10.28 g |
Studded, handcrafted (SION input norm) | 4.0% | about 10.40 g |
The studded rows come from DGFT's input-output norms, which allow 1.028 kg and 1.04 kg of gold per kg of studded export jewellery. These are trade allowances, not a law for retail shops. They are still the best public guide to how much extra gold real production consumes.
Why does the jeweller's wastage charge look bigger than the actual loss?
Because retail wastage (often called VA, value addition) usually bundles labour, design, overheads and margin with the metal loss. CaratLane's 2016 manufacturing interview put traditional jewellers' wastage charges at 3% to 35%. That is far above the 1–2.5% of gold a workshop loses on plain pieces.
Handmade, filigree and temple work do lose and use more labour than machine chains. But a 15–25% VA is mostly a pricing choice.
How does karat change the gold inside an ornament?
Karat tells you what share of the metal is pure gold. The rest is alloy that adds hardness and colour. For a 10 g finished ornament:
Karat (fineness) | Pure gold | Alloy metals |
24K (999) | 9.99 g | 0.01 g |
22K (916) | 9.16 g | 0.84 g |
18K (750) | 7.50 g | 2.50 g |
14K (585) | 5.85 g | 4.15 g |
Most Indian plain gold ornaments are 22K. 24K is too soft for most jewellery, and 18K or 14K is used where stones need firm settings. See [Is it Possible to Make 24 Carat Gold Ornaments?] and [Which Gold Is Best for Ornaments?].
How do you work out the gold needed and the cost of an ornament?
Use this method for any plain gold piece.
Decide the finished net weight. Example: a 20 g 22K necklace.
Add process loss for the method. At a handcrafted 2.25%, the goldsmith needs about 20.45 g of 22K metal.
Find the pure gold: 20 g × 0.916 = 18.32 g of fine gold in the finished piece.
Price it the retail way: net weight × rate, plus VA, plus 3% GST.
Bill for the 20 g necklace, as of 26 Oct 2026:
Line | Calculation | Amount |
Gold value | 20 g × ₹13,085 | ₹2,61,700 |
VA / making at 12% | 12% of ₹2,61,700 | ₹31,404 |
Subtotal | ₹2,93,104 | |
GST at 3% | 3% of ₹2,93,104 | ₹8,793 |
Final price | ₹3,01,897 |
Note that the 12% VA is worth about 2.4 g of gold at today's rate. That is roughly five times the 0.45 g a handcrafted workshop would actually lose. Rates are Groww's India averages; city rates differ slightly.
If you give old gold to a goldsmith, how much comes back as an ornament?
When you bring your own gold for a new piece, three deductions apply:
Purity adjustment. Old gold is tested; if it is below 22K, you get credit only for its pure gold content.
Melting loss. Small, often under 1% for clean gold, but more for pieces with solder or stones.
Making or wastage. Charged in grams of gold or in rupees.
Ask the goldsmith to write the input weight, tested purity, expected finished weight and the wastage in grams before work starts. Then weigh the finished ornament with them. The BIS CARE app lets you check the HUID on the new piece.
Frequently Asked Questions
How much gold is required to make a gold ornament?
You need the ornament's finished net weight plus about 1–2.5% for process loss on plain pieces. DGFT allows 0.90% for machine-made and 2.25% for handcrafted plain jewellery. A 10 g ornament therefore needs roughly 10.1–10.2 g of gold alloy.
How many grams of gold are needed to make a ring?
Most gold rings weigh 3–6 g, so they need about 3.0–6.1 g of metal including loss. A plain 4 g 22K band contains about 3.66 g of pure gold.
How much gold is needed to make a necklace?
A typical gold necklace weighs 20–60 g, and bridal harams can exceed 100 g. Add about 1–2.5% for manufacturing loss, or up to 4% if it is stone-set.
What is the difference between gross weight and net weight in gold?
Gross weight includes stones, beads and other materials. Net weight is the gold metal alone, and only net weight should be charged at the gold rate.
Is wastage the same as the gold actually lost?
No. Actual loss on plain jewellery is around 1–2.5%, and much of it is recovered. The retail wastage or VA charge, often 3% to 35%, also covers labour and margin.
How much pure gold is in a 22K ornament?
A 22K ornament is 91.6% pure gold. A 10 g 22K bangle contains 9.16 g of pure gold and 0.84 g of alloy metals.
Which authority sets purity for gold ornaments in India?
The Bureau of Indian Standards (BIS) sets purity grades and runs hallmarking. Each hallmarked piece carries the BIS logo, a purity mark such as 22K916, and a 6-digit HUID.
