What 19.2K gold is worth and how dealers price it
19.2K (Portuguese 800 gold) is 80% gold and is the legal jewellery standard in Portugal. It is known for the fine filigree work of the Minho region, including Viana hearts.
Look for the hallmark 800 or 19.2K. 19.2K is typical of traditional Portuguese filigree jewellery. Filigree is light for its size, so the weight of a large-looking Viana heart may be only a few grams. Collectable filigree can be worth more intact than melted.
Dealers weigh the piece, deduct stones and non-gold parts, and multiply the net weight by 0.8 to get the fine gold content. They then multiply by the CHF spot price per gram and apply their payout percentage — usually 60–75% of melt at shops and pawnbrokers, 80–90% at specialist buyers.
Worked example: a 8 g Portuguese filigree heart holds 6.40 g of fine gold. Enter 8 g and 19.2K in the calculator above to see its live melt value in CHF. Portuguese pieces carry an assay-office mark (a head of a dog or eagle, depending on age); photograph it before selling in case the piece is collectable.
Switzerland is home to several of the world's largest gold refineries, and Swiss buyers are used to precise assays. Local precious-metal control marks guarantee the fineness of Swiss-made jewellery.
