Estimates use the same USD spot basis as our calculators. Not financial advice, not a purchase offer, and not a guarantee of what any buyer will pay.
Heavier pieces often include hollow construction. Two similar-looking chains can differ by many grams—trust the scale, not the look.
Heavy lots reward checking for non-gold inserts and solder-heavy joints—buyers may test and adjust the offer.

Weighing & sorting tips
- If your pieces are mixed-karat, weigh each karat separately; otherwise a blended estimate can mislead you.
- If the item feels “too light,” it may be hollow; value is still weight-based, so grams matter more than looks.
