Weigh the chain you have, then match its karat. Rope, curb, Figaro and box describe link styles; they do not supply a gold weight. Hollow links can give a wide-looking necklace much less metal than solid links.
YOUR METAL WEIGHT
5.833 g fine gold
10K, 14K and 18K chain value
Link style and hollow versus solid construction
Cable, rope, box, wheat, curb and Figaro chains come in different widths and lengths. A link pattern is not a purity grade. Hollow construction describes empty space inside a link, whereas gold-filled or gold-plated describes a gold layer over another material.
Use the scale reading for hollow gold links at their confirmed karat; do not apply a second hollow-weight discount. For a plated or gold-filled chain, the whole scale weight is not gold alloy. Follow the coating mark and a documented layer assessment instead.
Clasp, end tag and pendant checks
Inspect the fastening and adjoining tags for quality marks. A replacement clasp or a detachable pendant needs its own check; do not assume the chain’s stamp describes every attached component. Exclude confirmed non-gold parts from the alloy grams.
One necklace, two lot items
If a confirmed 10 g 14K chain carries a separate 2 g 18K pendant, enter them as two items: 5.833 g fine gold in the chain plus 1.5 g in the pendant. Their combined 12 g should not all be valued at either one of those karats.
