Question: what is the difference in gold jewelry?
Answer: Pure gold (24k) is too soft and malleable to wear in jewelry, so the gold must be alloyed with other metals to give it strength and durability. 14k solid gold means 14 parts gold (58.3%) and 10 parts alloys (41.7%), while 18k solid gold means 18 parts gold (75%) and 6 parts alloys (25%).
