Decent prices and selection.
When one has to buy a piece of jewelry, one is often hesitant because the jewelry retail industry is notorious for ripping people off. At carl's, prices seem more reasonable than many other jewelers. One won't find museum quality pieces here, thats for sure - but for a person wanting to spend a couple of hundred, they will leave satisfied. The staff is patient and doesnt rush a person - browsers are made to feel welcome.
