Not necessarily, the piece must have 18k or 750 stamped inorder for it to be solid gold. However, many smaller pieces may not have a hallmark but still test 18k
It could mean 18 karat "hollow gold filled". I'm not familiar with a manufacturer's hallmark that is "HGF".

It should be stamped with a "hallmark." A hallmark for silver should be "925." This indicates 92.5% pure sterling silver. Another hallmark for silver could be "STERLING". A U.S. hallmark for gold would be 10K or 14K or 18K indicating the gold content. Pure 100% gold would be 24K; 10K is 41.67% gold; 14K is 58.33% gold; 18K is 75% gold.

A ring with an "18K" hallmark typically means it's solid 18K, but you can't rely on that. Hallmarks (stamps) are often wrong.
No. It may say '18k plated', but will never carry a hallmark or mark of fineness.
The 18k 756 is the hallmark for 18 carat gold although it should have an assay mark with it.
The hallmark for jewelry indicates the person who made the jewelry. Every designer has their own hallmark. You will often see numbers by a hallmark such as 925 which means it is sterling silver or 14k, 18k etc which indicate the amount of gold in the jewelry. Hope this helps.
