When investors turn to physical bullion, most focus on purity, brand, and storage. Yet one of the most overlooked factors is size — the specific unit weight of each bar.
At MAYAURUM, a division of Kestrel Assets Limited, buyers have always emphasised that bullion must not only hold intrinsic value but also maintain maximum liquidity. The ability to sell quickly, cleanly, and at or near spot price is essential.
After years of trading, vaulting, and liquidating physical bullion on behalf of a private client and various institutional accounts, MAYAURUM has adopted a clear position: investors should favour 1 Ounce for Gold, 1 Ounce for Platinum, and 1 Kilogram for Silver. These sizes consistently deliver the strongest secondary-market performance and the least friction when the time comes to sell.
Bill White, CEO of MAYAURUM, puts it plainly: “Liquidity is value. You do not fully own an asset until you can convert it back to cash at the proper price, without penalty. Choosing the right bar sizes is not a preference — it is a strategy.”
Gold: Why 1 Ounce is the Global Standard
The UMICORE 1 oz gold bar is recognised globally and trades with the narrowest spreads. It is large enough to minimise purchase premiums yet small enough to sell instantly without discounting. Larger bars such as 250 g or 1 kg often reduce buyer pools and attract markdowns. Smaller fractional bars suffer from excessive premiums that are rarely recovered upon resale.
Platinum: A Thin Market Demands the 1 Ounce Size
Platinum is a much smaller and more industrially driven market. The 1 oz bar is effectively the universal trading unit. Anything larger becomes difficult to resell at spot, and smaller bars rarely justify their cost. For investors seeking platinum exposure without liquidity risk, 1 oz is the only truly efficient choice.
Silver: 1 Kilogram Strikes the Ideal Balance
Silver’s lower value per gram makes size especially important. A 1 kg bar provides the best equilibrium of premium, storage efficiency, and resale value. Smaller pieces, such as 1 oz coins, are suitable for collectors but not optimal for investment. Larger formats, such as 5 kg or 1000 oz bars, are harder for private sellers to liquidate without discounting.
Why MAYAURUM Uses UMICORE as its Preferred Refiner
For years, Kestrel Assets Limited trading as MAYAURUM has standardised on UMICORE gold bullion wherever possible. This is deliberate and rooted in both performance and trust.
UMICORE is globally recognised, LBMA certified, and known for exceptional purity, serialised security, and ethical sourcing. Most importantly for clients, UMICORE gold bars consistently command the highest confidence from dealers, refiners, and private buyers alike, ensuring smoother liquidation and stronger resale pricing.
As Bill White notes: “Quality and recognition matter. UMICORE allows our client to hold gold bullion that is instantly trusted in every major market. When the brand, the size, and the purity are all correct, liquidity becomes effortless.”
Guidance for MAYAURUM Investors
For investors building a smart, liquid physical bullion portfolio, MAYAURUM recommends:
This approach ensures minimal buying premiums, maximum resale strength, and the greatest flexibility should you need to convert holdings back into cash quickly.
MAYAURUM will continue to advise its client based on real-market performance, not theory. A well-structured bullion portfolio is not measured by weight alone, but by how efficiently that weight can be monetised when needed.
