Rebecca
"Jewel" refers to a precious stone or gem(stone) itself, like a ruby or diamond. "Jewelry" refers to the accessories or ornaments worn on the body itself, like a ring or necklace. Ex: The king's crown includes many different types of precious jewels. Ex: My sense of style is quite simple, so I don't normally wear jewelry.
