Nugget

A nugget is a naturally occurring solid lump of precious metal — most commonly gold, but occasionally silver or platinum — found in its native, relatively pure form in geological deposits or alluvial stream beds, without requiring chemical extraction from ore. Gold nuggets are the result of natural geological processes — primary gold nuggets form in hydrothermal veins in rock, while secondary alluvial nuggets are formed when primary deposits erode and gold-bearing material accumulates in stream beds and river sediments over millions of years. Famous historical gold nuggets include the Welcome Stranger (2,316 troy ounces, found in Australia in 1869), the largest known gold nugget ever discovered. In modern commodity markets, gold nuggets are a niche collectible category — they trade at a significant premium over the spot gold price per troy ounce due to their rarity, natural origin, aesthetic value, and collector demand, rather than just their intrinsic metal content. For Indian gold investors and commodity market participants, understanding the distinction between nugget gold (natural, collector-grade) and refined gold (bars, coins, and ETF-backed gold of standardised purity) is important — investment-grade physical gold in India is measured by its refined purity (999.9 or 995 fineness) rather than its natural occurrence form. Indian gold ETFs, Sovereign Gold Bonds, and MCX gold futures are all referenced to refined 995-purity gold — not natural nuggets — for pricing and settlement purposes.
