How Gold Prices Work – And How They Affect Jewellery Design & Customer Costs

Your guide from The Diamond Tree Jewellery Studio, Rockingham WA

Gold has always held a special place in jewellery. It’s beautiful, durable, and has been treasured for thousands of years. But behind every ring, bracelet and pendant is one major factor that influences the final price: the gold market.

At The Diamond Tree Jewellery Studio, we’re transparent about pricing — especially when it comes to metal costs. Whether you’re having a custom piece designed or bringing in old jewellery to remodel, understanding how gold prices work will help you make the best decisions for your budget.

Here’s everything you need to know.

1. What Determines the Price of Gold?

Gold prices change constantly — sometimes hourly. This is because gold is traded globally as a commodity.

The main factors that influence the “spot price” of gold are:

Global supply and demand
Currency fluctuations (especially USD vs AUD)
Economic stability and inflation
Interest rates
Investor confidence

When global uncertainty rises, investors often buy gold, pushing prices up. When markets are stable, gold demand can ease and prices may soften.

Because Australia’s gold price is based on the international market and quoted in Australian dollars, any change in the AUD can also shift local gold pricing.

2. What is the “Spot Price” of Gold?

The spot price is the live market price for pure gold (99.99% or 24-carat) per gram. This is the raw, unrefined market value used across the jewellery and refining industries.

However — and this is important — jewellery is not priced at the spot price alone.

There are multiple additional factors that affect the final cost.

3. How Gold Purity Affects Jewellery Costs

Jewellery gold is not pure gold. It’s alloyed (mixed) with other metals to give it strength and colour.

Here’s how much actual gold is in each common jewellery carat:

9ct gold ≈ 37.5% pure gold
14ct gold ≈ 58.5% pure gold
18ct gold ≈ 75% pure gold
22ct gold ≈ 91.6% pure gold

This means the same design in 18ct gold uses twice as much pure gold as the same piece in 9ct gold — so the metal cost will be higher.

4. Why Jewellery Gold Costs More Than the Raw Spot Price

When jewellers purchase gold alloy for manufacturing, the price includes much more than the spot price of pure gold.

Jewellery gold prices include:

• Gold content (based on spot price)

The percentage of pure gold in the alloy.

• Alloying metals

Silver, copper, palladium or other metals added to achieve hardness and colour.

• Refining & manufacturing fees

Suppliers charge for producing high-quality, consistent alloys suitable for jewellery making.
These processes involve smelting, testing, rolling, milling and quality control.

• Supplier labour & overheads

Reputable suppliers like GSR invest heavily in machinery, staff and safety to produce clean, reliable alloys.

• Market movement allowances

Prices are updated daily (sometimes several times a day) to keep pace with the global gold market.

All of this means that 9ct, 14ct and 18ct alloy costs are all significantly higher than the basic spot price.

5. How Gold Prices Impact Custom Jewellery Costs

When you commission a custom piece — such as a wedding ring, pendant or remodel — the total price includes:

1. Metal cost

Based on the current day’s alloy price.

2. Design complexity

More intricate pieces often require more metal.

3. Labour & craftsmanship

Handmaking, stone setting, casting and finishing all add to the final price.

4. Findings and components

Clasps, chains, settings and other parts also fluctuate with gold prices.

Even a simple gold band contains many behind-the-scenes steps that are sensitive to metal cost changes.

6. How Your Old Gold Affects the Cost

When customers bring in their old gold, two key things happen:

We weigh and test your gold.
You receive a scrap credit based on the day’s scrap price.

Scrap prices are always lower than alloy purchase prices because:

Scrap must be refined back to pure gold
Refiners apply melting, testing and recovery costs
Old jewellery often contains solder, impurities and mixed carats

This means while using your old gold reduces the cost of a new piece, it doesn’t eliminate the cost of alloying, manufacturing or labour.

7. Why Jewellery Prices Change Over Time

If you’ve shopped for jewellery over the years, you’ve probably noticed prices rising. Gold has increased dramatically over the last decade.

Because metal makes up a significant portion of the material cost — especially for men’s rings and solid gold pieces — fluctuations in gold price can noticeably affect final quotes.

At The Diamond Tree Studio, we:

Update alloy prices daily
Follow current scrap prices for trade-ins
Provide fully transparent quotes
Explain exactly how gold pricing affects your job

We also use your gold wherever possible to offset rising market costs.

8. Choosing Jewellery When Gold Prices Are High

Even when gold prices are elevated, there are ways to stay within budget:

Choose 9ct gold instead of 18ct
Reduce band thickness or width
Add design detail without increasing metal volume
Use your old gold for a scrap credit
Consider blending metals (e.g., partial gold accents)

Custom jewellery doesn’t have to be expensive — it just needs thoughtfully designed and honestly priced.

Final Thoughts: Understanding Gold Prices Empowers You

Gold pricing can seem complicated, but it plays a huge role in jewellery design, manufacturing and cost transparency. When you understand how metal prices work, it becomes much easier to make informed choices about your jewellery.
