What 16K gold is worth and how dealers price it
16K contains 66.7% gold. It is a historic standard that appears in older Central European jewellery and in some Russian and Soviet-era pieces.
Look for the hallmark 667 or 16K. 16K is typical of older Central European and Russian pieces. Old pieces may carry only a maker's mark and a local assay mark rather than a clear number, so testing is essential.
Dealers weigh the piece, deduct stones and non-gold parts, and multiply the net weight by 0.667 to get the fine gold content. They then multiply by the CZK 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 10 g antique 16K brooch holds 6.67 g of fine gold. Enter 10 g and 16K in the calculator above to see its live melt value in CZK. Antique brooches and lockets often have base-metal pins or glass inserts, which are deducted from the weight before the gold is valued.
Czech jewellery is hallmarked by the state Assay Office (Puncovní úřad). Buyers commonly quote per gram of 585 gold, so convert your karat using the calculator before comparing.
