I believe you are referring to "rolled" gold, which is another name--used historically--for gold-filled.
Gold-filled/rolled gold refers to a metal on which a layer of gold has been bonded by fusing.
A standard practice is to clad the base metal with 10% (weight) 14k gold. Since 14k gold is 58.3.% gold it means the final result, if it were melted down and assayed, would equal 5.83% pure gold. The gold used may also be 12k--50% gold. If 12k gold is used, then 5.00% of the goldfill/rolled gold would be gold.
Gold-filled/rolled gold is NOT the same as gold-plate.
Gold-plate is defined by the Federal Trade Commission's regulations as being an impermanent finish because a very very small layer of gold is layered on base metal, usually using a dipping process and an electric current but sometimes by spraying the gold on.
Gold-fill/rolled gold is considered a much more durable gold-product and you will pay more for it than gold-plate. Gold-fill/rolled gold is produced by fusing a layer of gold to a base-metal core.
Gold-fill/rolled gold is particularly long-wearing when used for jewelry items that do not come in constant contact with the skin--for example, a pendant. It is less long-lasting for pieces of jewelry that receive more wear and tear when being worn--for example, rings and bracelets.
