Bullion and gold-pound prices from companies
A bar sells at the metal price plus a small fabrication cost. Jewellery sells at the metal price plus a much larger making charge, because it is design and handwork. On resale the making charge is lost either way. This is why buyers saving in gold lean towards bars and gold coins, while buyers who want to wear it buy jewellery.
Bars come in weights from one gram up to a kilo. The smaller the bar, the higher the fabrication cost per gram, because minting, packaging, and certification cost roughly the same regardless of weight. A 50 gram bar is cheaper per gram than fifty one gram bars. In exchange, small bars are easier to sell off a piece at a time.
A reputable bar arrives in a sealed pack with a certificate carrying a serial number, weight, purity, and mint. Do not open the seal, as opening it lowers the resale price and forces a fresh assay. On jewellery, the official hallmark is what proves the purity, so check for it before paying.
