I grew up paying attention to jewelry in that some kid in a wedding called the ring bearer held rings for people in a wedding ceremony. Outside of that, I sometimes wore a necklace with a cross when I was a kid. Somewhere in/after high school I lost total desire for all clothing accessories, including a watch. At one point I even wore one earring, it was a yellow gold hoop.
I prefer not to wear jewelry, but I do sometimes need to wear a wrist watch.
A 115,000 year old Neanderthal artifact shows their jewelry predates modern day human (Homo sapiens) jewelry. Check out Jewellery#Prehistory at Wikipedia for more about the artifact.
Today most people wear a wrist watch, something I'll guess to say did not exist in Neanderthal times.
National Geographic simply explains things in Neanderthals 101.
