To check if gold is 18k or 22k, use a gold testing kit. Firstly, clean the jewelry thoroughly. Scratch a small area of the gold onto the testing stone. Apply acid from the kit corresponding to 18k and see if the mark stays. If it disappears, it's less than 18k; if it stays, apply the 22k acid test. Comparing the reaction will help ascertain the gold's karat. Professional jeweler assessments can confirm the results reliably.
