Buy Gold Bars by Weight – Investment Gold from 1 Gram to 1 Kilogram

Gold bars are one of the most efficient and widely recognised forms of physical gold investment. Unlike gold coins, gold bars are produced primarily for investors rather than collectors, which means manufacturing costs — and therefore premiums over the spot price — are generally lower, especially in larger weights. CelticGold offers a comprehensive range of gold bars from LBMA-certified refiners in every major weight class, from 1 gram up to 1,000 grams (1 kilo).

How Gold Bars Are Produced

There are two established methods for producing gold bars: casting and minting.

Cast gold bars are made by melting gold granules with a fineness of at least 999.9/1000 and pouring the molten metal into ingot moulds. The fineness, fine weight, and manufacturer's hallmark are then stamped into each bar by hydraulic press. Cast bars typically have a distinctive rough, crystalline surface. Small scratches or minor handling marks are far less visible on cast bars than on minted ones, making them particularly robust for long-term storage. Cast production is the standard method for bars from 250 grams upwards.

Minted gold bars are produced similarly to coins: gold is rolled into sheets of precise thickness, blanks are punched out, and each blank is then struck with the bar's design and markings in a coining press. Minted bars have a smooth, mirror-like surface and sharper detail — which makes them more susceptible to surface scratches but also more visually impressive. Minting is the standard for bars up to 100 grams.

Gold Bar Weights – Overview and Typical Use Cases

The 1 oz and 100 g Gold Bar – The Most Popular Investment Weights

The 31.10 gram (1 troy ounce) and 100 gram gold bars are the most widely purchased by private investors across Europe. They offer an attractive balance: premiums are significantly lower than small bars, resale is straightforward with any reputable precious metals dealer, and the investment amount remains manageable. Both weights are available from leading manufacturers including Argor-Heraeus, Heraeus, and Valcambi.

Small Gold Bars – 1 g to 10 g

Small gold bars from 1 gram to 10 grams carry the highest premiums per gram of fine gold, as manufacturing and packaging costs are spread over a smaller gold content. However, they serve an important purpose: they make gold accessible as a gift or as a first investment with a very low entry cost. A 1 gram gold bar is available in elegant gift packaging from manufacturers such as Umicore and Heimerle + Meule, making it a thoughtful and lasting gift for birthdays, christenings, or anniversaries. Alternatively, small amounts can be accumulated cost-efficiently through the CelticGold Metal Account and later exchanged for physical bars.

Large Gold Bars – 250 g to 1 Kilo

For investors looking to maximise gold content per euro invested, the 250 gram and 1,000 gram (1 kilo) cast bars offer the lowest premiums available. The kilo bar in particular is the standard unit for institutional investors and carries a premium of approximately 1% above spot. Large bars stack efficiently in safes or professional vaults, making them ideal for secure long-term storage. For professional storage options, see our secure storage service.

Gold Bar Pricing – Spot Price and Premium Explained

The price of a gold bar consists of two components: the current gold spot price and the manufacturer's or dealer's premium. The spot price of gold is determined by the major exchanges worldwide, with the London Bullion Market (LBMA) fixing being the global reference price, set twice daily. The premium reflects the costs of refining, minting, packaging, certification, and distribution. As a rule, the larger the bar, the lower the premium per gram.

VAT on Gold Bars

Gold bars with a minimum purity of 995/1000 are exempt from VAT throughout the European Union. All gold bars sold by CelticGold meet this requirement. The VAT exemption for investment gold is regulated under EU VAT Directive 1998/80/EC and implemented in national legislation across all EU member states.

Gold Bars vs. Gold Coins – Which is Right for You?

Gold bars typically carry lower premiums than gold coins of equivalent weight, making them more cost-efficient as a pure investment vehicle. Gold coins, on the other hand, benefit from additional anti-counterfeiting features, divisibility through fractional sizes, and broader recognition in private trading. Many experienced investors combine both: larger bars for efficient capital storage and gold coins for flexibility and liquidity. For maximum cost efficiency without manufacturing premiums at all, the Fine Gold Metal Account allows purchases from as little as 0.1 gram at spot price.
