Buying a gold necklace and buying a gold bar do not mean making the same investment in two different forms. Both contain a precious-metal component, but the price paid, purity, taxation, ease of resale and, above all, the relationship between the value of the gold content and the final price can differ considerably. Jewellery is also purchased for its design, craftsmanship, brand and aesthetic function; investment gold, by contrast, is bought primarily to gain exposure to the metal's value. A piece of jewellery can therefore increase in value if gold rises, but should not automatically be treated as equivalent to a bar.

The distinction is also legal. Italian legislation specifically defines what qualifies as investment gold: this includes, in particular, bars and wafers weighing more than one gram with a purity of at least 995 thousandths, and certain gold coins with a purity of at least 900 thousandths and additional requirements. An ordinary piece of 18-carat gold jewellery, although containing a significant amount of precious metal, therefore does not automatically fall within this category.

The first factor to examine is purity

Pure gold is conventionally described as 24 carats, corresponding to a purity close to 999 thousandths. Jewellery often uses gold of a lower fineness because pure gold is very soft and unsuitable for many items intended to be worn.

18-carat gold, very common in Italy, contains 75% fine gold, or 750 thousandths. The remaining 25% consists of other metals used to give jewellery its colour, hardness and mechanical properties.

This means that a 20-gram necklace in 18-carat gold does not contain 20 grams of pure gold. Its theoretical fine-gold content is:

20 × 0.75 = 15 grams of pure gold

This is the figure to use when comparing the jewellery with the metal's price.

A bar qualifying as investment gold must instead have a purity of at least 995 thousandths, so almost all its weight consists of fine gold.

The price of jewellery and the value of its gold content are different things

Suppose an 18-carat gold necklace weighs 20 grams. As we have seen, it contains approximately 15 grams of pure gold. If, purely as an example, pure gold were worth 100 euros per gram, the theoretical value of the metal it contains would be:

15 × 100 = 1,500 euros

The necklace could nevertheless be sold by a jeweller for 2,500, 3,000 or even many more euros.

The difference does not necessarily represent an “unjustified markup”. The final price may include craftsmanship, design, distribution, the manufacturer's and retailer's margins, marketing, any brand value and taxes.

The point is different: if the purpose of the purchase is to gain economic exposure to the price of gold, you need to know that only part of the jewellery's price corresponds to the precious metal.

The premium over the metal

We can informally call the difference between the price paid for an object and the value of the metal it contains a premium.

In the previous example:

The price paid is therefore approximately 67% higher than the theoretical value of the metal alone.

If the gold price rose by 20%, the metal content's value would increase from 1,500 to 1,800 euros. This does not mean, however, that the necklace purchased for 2,500 euros could automatically be resold for 3,000 euros.

This is where the main difference between jewellery and investment gold becomes apparent.

When you resell jewellery, the market may value it almost entirely as gold

New jewellery is purchased at retail and incorporates many price components. When it is resold to a dealer buying primarily to recover the metal, many of those components may no longer have value.

The buyer may essentially reason as follows:

weight × gold fineness × fine-gold price − dealer's margin/costs

The craftsmanship that increased the original price may therefore receive no recognition, or only very limited recognition.

This explains why jewellery bought new can show a very large difference between its purchase price and immediate resale value.

It does not mean that the jewellery was necessarily “overvalued”: it simply means the retail market and the used-gold market value different characteristics.

A bar, by contrast, is designed to track the metal more closely

For a gold bar, most of the value comes directly from the quantity of fine gold it contains. Even here, however, there is a spread, meaning a difference between the price at which you can buy and the price at which you can resell.

A small bar may carry a higher percentage premium over the gold price than a larger bar, because production, certification and distribution costs weigh more heavily on smaller sizes.

Buying investment gold therefore does not mean buying exactly at the international spot price and reselling at the same price.

The difference compared with jewellery is that the price is much more directly linked to the quantity of fine gold.

Investment gold: the legal definition matters

Italian law does not regard every object made of gold as “investment gold”. Law no. 7 of 17 January 2000 defines it as including bars or wafers weighing more than one gram with a purity of at least 995 thousandths. Coins must have a purity of at least 900 thousandths, have been minted after 1800, be or have been legal tender in their country of origin, and meet additional requirements concerning their price relative to the value of their gold content.

An 18-carat ring, chain, bracelet or gold watch therefore does not become “investment gold” simply because it contains precious metal.

This distinction also has significant tax implications.

The VAT difference

One of the most important aspects concerns VAT. Italian rules provide a specific regime for investment gold, and Article 10 of Presidential Decree (DPR) 633/1972 provides for VAT exemption for transactions falling within that regime.

Ordinary jewellery sold to consumers, by contrast, is generally subject to the standard VAT applicable to the item.

This creates a significant economic difference. For jewellery, part of the price paid also reflects the taxation applied to the sale, while investment gold benefits from a specific regime precisely because it is treated differently from a consumer good.

This is another reason why simply comparing “the cost of a gram of necklace” with “the cost of a gram of gold bar” without considering the price structure can lead to incorrect conclusions.

Jewellery can still retain value

Saying that jewellery is not equivalent to investment gold does not mean it has no value as an asset. On the contrary, it contains a real asset whose market price can rise over time.

If a necklace contains 15 grams of fine gold and the gold price doubles, the minimum value attributable to its metal content also increases significantly.

Jewellery therefore offers a kind of minimum intrinsic value linked to the metal, net of spreads, melting costs and the buyer's margins.

This distinguishes it from many other consumer goods that can lose almost all their value through use.

But the existence of residual value does not mean the purchase is automatically a good financial investment.

Brand value can change the reasoning entirely

There are also pieces of jewellery whose value does not depend primarily on their gold weight.

An object from a highly sought-after brand, a rare piece, historic jewellery or a work of high jewellery can retain or increase its value for reasons completely unrelated to the metal's price.

In this case, economic value derives from:

Such jewellery should be analysed almost as a collectible, rather than simply as a quantity of gold.

For ordinary commercial jewellery, however, it is much more prudent to assume that its recognised resale value may mainly reflect the metal it contains.

An example: a 16-gram piece of 18K gold jewellery

Consider a piece of jewellery weighing 16 grams, made of 18-carat gold.

The theoretical quantity of pure gold is:

16 × 0.75 = 12 grams

Again, solely to simplify the calculation, suppose the price of pure gold is 100 euros per gram.

The theoretical metal content is worth:

12 × 100 = 1,200 euros

If the jewellery is purchased for 2,000 euros, 800 euros of the price are not directly explained by its fine-gold content.

If gold rose by 25%, the theoretical value of the metal would become:

1,200 × 1.25 = 1,500 euros

The gold price has risen significantly, but the theoretical value of the metal would still be below the 2,000 euros originally paid.

A much larger increase would be required to recover the entire price through the gold's value alone.

This shows why buying jewellery on the assumption that “gold goes up anyway” can be incomplete reasoning.

How far must gold rise to recover the premium?

We can extend the example.

Jewellery price: 2,000 euros

Initial value of the gold content: 1,200 euros

For the metal alone to reach a value of 2,000 euros, it must rise by:

2,000 ÷ 1,200 − 1 = approximately 66.7%

This does not account for the fact that, in an actual sale, a dealer might offer less than the metal's full theoretical value.

The gold price would therefore need to rise even further for net resale proceeds to equal the price originally paid.

This is one of the simplest ways to understand the economic difference between buying gold and buying something made of gold.

24K does not automatically mean a better investment

The opposite argument can also be oversimplified. An object made of 24-carat gold contains a higher proportion of fine metal, but does not automatically become investment gold.

What matters is its legally recognised form, purity, relevant market and purchase price.

A 24-carat necklace can still include substantial craftsmanship costs and a commercial margin. If it is resold mainly for its metal weight, part of the original price can be lost just as with 18K jewellery.

Higher purity narrows the gap between the object's weight and the quantity of fine gold, but does not necessarily eliminate the commercial premium.

Physical gold and returns: no coupons or dividends

Another difference from many financial investments is that physical gold does not generate cash flows by itself.

A share may distribute dividends. A bond may pay coupons. A deposit may pay interest.

A gold bar produces nothing during the holding period. The economic result depends essentially on the difference between purchase and sale prices, net of costs incurred.

This means gold's return depends entirely on the asset's appreciation.

The same naturally applies to the metal contained in jewellery.

Storage and security are real costs

Owning physical gold also creates a problem that is not always included in calculations: storage.

A gold bar or piece of jewellery must be kept securely. This may mean using a safe, a bank safe-deposit box, insurance or other protective systems.

These costs reduce the investment's effective return.

Jewellery also carries a risk of damage or loss during use, precisely because the item serves both as an asset and as something decorative.

Ease of resale differs

A standardised bar made by a recognised producer and accompanied by the relevant documentation can normally be valued fairly simply using its weight, purity and the current metal price.

Valuing jewellery can be more complicated. Its weight, fineness, any stones, condition and prospects of being resold as jewellery rather than material for melting must be checked.

Two dealers may therefore offer very different prices.

This generally makes the used-jewellery market less transparent than the market for standardised investment gold.

Gold and diversification

Gold is often used to diversify wealth because its performance can differ from that of shares and bonds. Here too, however, oversimplification should be avoided.

Gold can experience very long periods of stagnation or decline and produces no income while held. Its price can also be influenced by inflation, real interest rates, financial demand, central-bank purchases, the US currency and geopolitical tensions.

The fact that it is a real asset therefore does not mean its price can only rise.

Jewellery adds the problems of the initial premium and ease of resale to the risk associated with the gold price.

Buying jewellery can make perfect sense

It is important, however, not to turn this comparison into a judgement that buying jewellery is economically wrong.

Jewellery also provides personal utility. It can be worn, given as a gift, passed down and hold aesthetic or sentimental value. The additional price above its gold content pays precisely for these characteristics.

Someone can therefore knowingly buy a necklace at more than its metal value and still consider it an excellent purchase.

The mistake arises only when the jewellery's retail price is interpreted as if it represented an investment entirely in gold.

A more accurate way to think about it is:

jewellery value = metal value + value of craftsmanship/brand/design/personal utility

whereas for a bar:

value ≈ metal value + relatively limited production and distribution premium

The two transactions meet different objectives.

How to assess jewellery as an asset

To understand how much of the price paid actually represents exposure to gold, four pieces of information are enough:

the jewellery's weight, gold fineness, current fine-gold price and price paid.

Suppose:

The percentage of the price explained by the metal is:

1,875 ÷ 3,000 = 62.5%

The remaining 37.5% comes from other elements.

This indicator does not establish whether the jewellery is “expensive” or “cheap”, because a high-quality or branded product can justify a large premium. It does, however, show how much of the purchase directly follows gold's value.

Jewellery should not be accounted for as cash

Finally, there is a practical consequence for managing personal wealth. If we own 10,000 euros of jewellery purchased at retail, it would be prudent not to automatically regard it as 10,000 euros of immediately realisable assets.

The resale value could be lower.

A conservative assessment could distinguish between:

This is the same principle discussed in relation to wealth and liquidity: what we paid for an asset does not necessarily determine what we can obtain by selling it today.

Conclusion

Investment gold and jewellery share one obvious characteristic: both can contain physical gold. Economically, however, they are different products.

Investment gold is designed primarily to provide exposure to the metal's value, with high purity, standardised forms and a price generally closer to its fine-gold content. Italian legislation precisely identifies which bars, wafers and coins can fall within this category.

Jewellery, by contrast, is a composite good. Its price incorporates gold, craftsmanship, distribution, design, any brand value and aesthetic function. The amount paid can therefore be far above the metal value and, on resale, part of that premium may not be recovered.

The right question is therefore not: “Is gold jewellery an investment?” but: “How much of the price I am paying actually depends on gold, and how much am I paying for everything else?”

If the main objective is exposure to gold's value, the distinction is fundamental. If instead you want an object to wear that also retains an asset component linked to the metal, jewellery can fulfil that function perfectly well.

But these are two different objectives, and confusing them can easily lead to a mistaken assessment of the purchase's effective return.
