Gold and platinum are different metals, not different grades of the same metal
Gold and platinum are both precious metals used in jewellery and investment markets, but they have different physical properties, benchmark prices and retail structures. A one-gram price comparison is therefore only one part of the decision.
LBMA publishes separate global benchmark prices for gold and platinum. IBJA also publishes separate India reference data for gold purity categories and platinum 999. The two markets can move differently from day to day.
Price: there is no permanent winner
It is common to hear that platinum is “always more expensive” than gold or that gold is “always more valuable.” Neither statement is a reliable market rule. Their benchmark prices change independently.
For a current comparison, use same-day benchmark data rather than a rule of thumb. Then account for the different amount of metal used in a finished jewellery piece.
Purity and composition
Gold jewellery is commonly sold by karat/fineness. BIS permits hallmarking grades including 22K/916 and 18K/750. White, yellow and rose gold are still gold alloys; their colour comes from the alloying metals and surface finish.
Platinum jewellery uses platinum-group alloys. GIA describes platinum as a naturally white precious metal valued for durability and corrosion resistance. Because platinum jewellery is often produced at high platinum fineness and the metal is dense, a platinum ring of similar dimensions can contain more precious-metal mass than a gold ring.
| Feature | Gold | Platinum |
|---|---|---|
| Global benchmark | LBMA Gold Price | LBMA Platinum Price |
| Common India jewellery purity language | 22K/916, 18K/750, etc. | Platinum fineness varies by product |
| Natural colour | Yellow; alloys create white/rose colours | Naturally grey-white |
| Density | Lower than platinum | Higher |
| Surface finish | White gold may use rhodium plating | Naturally white; no rhodium needed for colour |
Jewellery price is more than metal price
A finished ring or chain includes design, workmanship, brand and possibly stones. Two pieces with the same total weight can have very different metal content and manufacturing cost.
This is especially important when comparing a platinum ring with a white-gold ring. White gold is a gold alloy that may be rhodium plated; platinum is a different precious metal. Similar colour does not mean identical composition or value.
Maintenance differs
GIA notes that white gold is often rhodium plated and may need replating as the surface wears. Platinum does not need rhodium plating to be white, although platinum jewellery can still scratch and develop a surface patina over time.
Maintenance cost therefore depends on the specific product and finish, not simply on the metal name.
Resale and exchange need retailer-specific checks
Do not assume the purchase-price gap will be preserved when selling. A future offer can depend on verified metal fineness, net metal weight, prevailing benchmark, stones, condition and the retailer's buyback policy.
Ask the seller:
- What fineness is the metal?
- What is the net metal weight excluding stones?
- What benchmark is used for exchange or buyback?
- Are making charges or design premiums recoverable?
- Is there a separate deduction for testing or refining?
Which metal is better for jewellery?
There is no universal answer. Gold offers a wide range of colours, karats and traditional Indian jewellery styles. Platinum offers a naturally white, dense metal that can suit buyers who want a white-metal look without rhodium plating.
Choose based on design, wear, budget, purity, maintenance and resale terms rather than assuming the higher current per-gram benchmark is automatically the better purchase.
FAQ
Is platinum always more expensive than gold?
No. Gold and platinum have separate markets and benchmark prices, so their relative price can change.
Is white gold the same as platinum?
No. White gold is a gold alloy, often rhodium plated. Platinum is a different precious metal.
Should I compare platinum and gold only by price per gram?
No. Also compare purity, total metal weight, design/manufacturing cost, stones, maintenance and buyback terms.
