18k hgf would stand for 18k heavy gold filled ( not solid gold )
It could mean 18 karat "hollow gold filled". I'm not familiar with a manufacturer's hallmark that is "HGF".
Heavy gold filled
An angle whose measure is 20 degrees!
"HGF" or hollow gold filled jewelry is considered a fine jewelry and should be treated with the same caution when cleaning. To clean HGF jewelry a solution of Mr. clean, water, and ammonia can be used. Mix half Mr. Clean and water with a small amount of ammonia. This is safe for all types of fine jewelry and is used by many jewelry stores. Allow the jewelry piece to soak for 15 seconds in this solution then rinse with water and dry.
Then p/q is a rational number.
