Gold-filled

Gold-filled is a thick sheet of 10 to 14 karat gold bonded with heat and pressure to a brass core. The gold layer usually represents at least 5% of the piece's total weight, so it is far more durable than simple plating.

Properties #

• Composition: brass or copper core with a 10-14K gold layer.
• Gold thickness: many times that of an electroplated coat.
• Process: bonding by heat and pressure, not electrolysis.
• Marking: usually stamped “GF” or “1/20 14K GF”
• Price: between plating and solid gold.

Uses in jewelry #

• Everyday chains, earrings and pendants.
• Handmade jewelry with wire and sheet.
• An alternative to solid gold with good durability.
