A 10K yellow gold Miami Cuban chain's weight depends on width and length. Reference weights for solid-link construction: at 6mm wide and 20 inches long, approximately 18 to 28 grams; at 8mm wide and 20 inches, approximately 30 to 45 grams; at 10mm wide and 20 inches, approximately 45 to 70 grams; at 12mm wide and 20 inches, approximately 60 to 90 grams.
At 10K and $3,000/troy oz gold, the gold content value of these weights: 25 grams = approximately $1,006; 40 grams = $1,610; 60 grams = $2,415; 80 grams = $3,220. These are significant values that demonstrate why gram weight matters so much for Miami Cuban chain purchases — the difference between a 25-gram and 60-gram chain of the same stated 8mm width is over $1,400 in gold content.
The substantial weight of a quality solid-link 10K Miami Cuban chain is one of its most defining physical characteristics. Buyers new to Miami Cuban chains are consistently surprised by how heavy they are — this weight is the clearest tactile confirmation that you are handling real gold chain, not plated base metal.
