1 kg Cast Gold Bar | Valcambi

1 kg Valcambi Cast Gold Bar — flagship of the cast bar series with the lowest premium per gram, raw surface texture and full LBMA accreditation

1 kg of 999.9/1000 fine gold (.9999) in a cast bar format from Valcambi SA — a Swiss refinery with LBMA Good Delivery accreditation since 1968. Each bar carries an individual serial number and is delivered with an assay card confirming weight, fineness and authenticity.

The cast bar is produced by pouring molten gold into a graphite mould and allowing it to cool under controlled conditions — a method used for millennia and the oldest technique for shaping precious metal. Each piece has a unique, slightly rough surface texture that distinguishes it from minted bars with their smooth, mirror-like finish. The 1 kg cast is the flagship of Valcambi's cast bar series — the largest and heaviest casting in the range, delivering the absolute lowest premium per gram available in retail. It is the weight chosen by buyers making single purchases of the highest unit value.

Technical specification

Why this product?

• Traditional casting technique — the cast bar is the oldest form of bullion bar. The 1 kg format embodies this character in its purest form — a substantial, heavy casting with the most pronounced surface texture in the entire series, displaying the full solidification cycle of the metal.
• 999.9/1000 fineness (.9999) — identical purity standard to Valcambi's minted bars. The production technique does not affect fineness — both cast and minted bars contain the same amount of fine gold per gram.
• LBMA Good Delivery since 1968 — Valcambi meets the highest quality standards of the London Bullion Market Association regardless of production form.
• Lowest premium per gram in the series — the 1 kg cast is the final and largest weight in Valcambi's cast bar range. Fixed production costs are spread across the maximum amount of metal, yielding the absolute lowest premium per gram available in retail gold bullion.
• Individual serial number — stamped directly on the bar and confirmed on the assay card, ensuring full product traceability on the secondary market and at resale.

Valcambi SA — Swiss precious metals refinery

Valcambi SA has operated since 1961 from Balerna in Canton Ticino, southern Switzerland. The refinery processes the four main precious metals — gold, silver, platinum and palladium — with an annual capacity exceeding 2,000 tonnes. It ranks among the world's largest and most recognised precious metals processors, serving central banks, state mints and global bullion dealers.

Valcambi obtained LBMA Good Delivery accreditation for gold in 1968. The refinery holds accreditations for all four main precious metals — one of the few worldwide with the complete set. The Balerna facility runs the entire production cycle — from refining through casting and minting to final packaging.

Valcambi produces both minted bars with a smooth surface and cast bars with a characteristic rough texture — both forms in identical 999.9/1000 fineness. The refinery operates responsible sourcing programmes in accordance with OECD Due Diligence and LBMA Responsible Gold Guidance standards, with regular independent audits ensuring full supply chain traceability.

Casting technology — cast bar vs. minted bar

The cast bar (pourbar) is produced by pouring molten gold at over 1,064 °C into a precision graphite mould. After controlled cooling, the bar is removed, cleaned and marked — the producer logo, weight, fineness and individual serial number are mechanically stamped into the surface.

Unlike minted bars, which are cut from a gold strip and struck in a press to achieve a smooth mirror finish, cast bars retain the natural surface structure formed during metal solidification. The result is a matte, slightly irregular texture — each piece is a visual one-off.

The casting technique is the oldest known method of shaping precious metal into standardised trade units — used from antiquity through to today's LBMA refineries. Modern Valcambi cast bars combine this traditional method with 21st-century quality control: each bar is weighed to 0.01 g accuracy and spectrometrically verified for fineness.

Casting a one-kilogram bar is the most demanding process in the entire cast bar series. The large mass of molten metal means the longest solidification time in the graphite mould, and managing the temperature gradient across a cross-section of 80 × 117 mm requires particularly precise control of cooling rate. Cooling too fast risks internal stress; cooling too slowly may produce uneven density. The result of a correctly executed process is a solid, homogeneous casting with the richest and most varied surface texture in the series — a visible record of the full solidification cycle of one kilogram of gold.

Formats and weights — Valcambi cast gold bars

Valcambi SA produces cast gold bars in five weights: 50 g, 100 g, 250 g, 500 g and 1 kg. The cast bar series complements the full range of minted bars (0.5 g to 1 kg) and the CombiBar format.

The 1 kg format is the final and largest in the series — the weight at which the premium per gram reaches its absolute minimum in retail. The one-off outlay is the highest in the entire range, but the per-gram cost of metal is the lowest of all available weights. It is the choice of buyers who prioritise the minimal premium over spot and concentrate value in a single, large-format casting.

A full overview of available weights can be found in the gold bullion bars category. Current precious metals prices at precious metals prices.

What to consider before buying?

Before purchasing, check the current gold price and compare the product price with the spot price. The premium over spot for the 1 kg format is the lowest in the entire retail range — the absolute minimum cost per gram of gold bullion. The jump in premium from 1 kg to 500 g is relatively small, while the difference between 1 kg and smaller weights (250 g, 100 g, 50 g) increases markedly.

The matte, slightly rough surface is a natural feature of the casting process. In the 1 kg format, the texture is the most pronounced and varied in the entire series — the large casting surface displays the full spectrum of solidification marks that give each piece a unique, distinctive appearance. For resale, what matters is the individual serial number, assay card and producer reputation (Valcambi, LBMA Good Delivery).

FAQ — Frequently asked questions

What is the difference between a cast bar and a minted bar?

A cast bar is produced by pouring molten gold into a mould, giving it a matte, slightly rough surface — each piece is unique. A minted bar is cut from a gold strip and struck in a press, producing a smooth mirror finish. Both forms contain identical 999.9/1000 gold per gram and are fully tradable on the bullion market.

What is the fineness of the 1 kg Valcambi cast gold bar?

The bar is made of 999.9/1000 fine gold (.9999) — the highest purity standard in bullion bars, identical across all Valcambi weights and production forms.

What are the dimensions of the 1 kg Valcambi cast gold bar?

The bar measures approx. 80 × 117 × 8 mm. Due to the casting process, dimensions may vary slightly between pieces — this is a natural feature of the production technique.

Why does the kilo bar have the lowest premium in the entire series?

Fixed costs of production, packaging and handling are spread across the maximum amount of metal — 1,000 g of fine gold. The larger the weight, the smaller the share of fixed costs in the final price. The 1 kg format is the final weight in Valcambi's cast bar series — no other cast weight offers a lower premium per gram.

What weights are available for Valcambi cast gold bars?

Valcambi SA produces cast gold bars in five weights: 50 g, 100 g, 250 g, 500 g and 1 kg. The 1 kg format is the largest and final weight — delivering the absolute lowest premium per gram. All weights have identical fineness of 999.9/1000 (.9999).

Is the 1 kg cast gold bar VAT-exempt?

Yes. Gold bullion in bar form meeting the conditions of EU Directive 98/80/EC is exempt from value added tax — regardless of whether the bar is cast or minted.

How do I buy the 1 kg Valcambi cast gold bar from GoldInvest24?

Simply add the product to your basket and complete the order. Before purchasing, check the current gold price and compare the premium with other weights in the gold bullion bars category.
