18k gold bar: a gift or an investment?
Updated October 2026 · 6 minute read
A gold bar is one of the gifts we are asked for most often for births, christenings and anniversaries. But "gold bar" does not always mean the same thing: an 18 carat gold bar and an investment gold bar are different objects, with different rules and values. Here is what to know before you choose, explained plainly.
What an 18 carat gold bar is
It is a small bar of 18kt gold, hallmarked 750: out of 1,000 parts of metal, 750 are pure gold and 250 are other metals that make it harder. It is the same gold used in fine jewellery.
The bar we offer is the UnoAerre Lucky Bar, made in Arezzo by one of Italy's most historic gold manufacturers. It is stamped with the 750 hallmark and the maker's identification mark, 1 AR, which guarantees its origin. It comes in its original box with a certificate of authenticity.
18 carat or investment gold: the differences
Under Italian and EU rules, investment gold means bars or wafers of a weight accepted by the bullion market with a purity of at least 995 parts per thousand (almost 24 carats). An 18kt gold bar is not investment gold.
| 18kt gold bar (750) | Investment gold (995–999.9) | |
|---|---|---|
| Purity | 75% pure gold | At least 99.5% pure gold |
| Colour and finish | Jewellery yellow gold, shiny and durable | Deep yellow, soft metal |
| VAT on purchase | Yes, like jewellery | Exempt |
| Price | Gold value + craftsmanship + VAT | Very close to the gold price |
| Personal engraving | Yes | Usually not |
| Best for | A meaningful, lasting gift | Financial investment |
Our honest advice: if your only goal is to invest, investment gold is more efficient. If you want a gift with real value, that lasts forever and can be personalised, an 18kt gold bar is a beautiful choice.
How much it is worth over time
An 18kt gold bar always keeps the value of its pure gold: a 10 gram bar hallmarked 750 contains 7.5 grams of fine gold. This value follows the gold price, which has risen a lot in recent years but can also fall.
When you sell it, you receive the value of the gold it contains at the day's price, not the price paid for the gift, which also includes craftsmanship and VAT. The same principle applies to all gold jewellery.
Why choose it as a gift
- It has real value: unlike many gifts, gold does not wear out or go out of fashion.
- No guessing tastes or sizes: no sizes, colours or styles to get right.
- It is personal: a name, a date or a message can be engraved on the back.
- It lasts a lifetime: given at birth, the child will find it as an adult, as a keepsake and a small nest egg.
The most common occasions in our shop are births and christenings, then 18th birthdays, graduations, weddings, anniversaries and retirements.
