For example galadriel in the third age i would argue was more powerful than the second age or first age in part because of Nenya. She was also powerful because she was taught by Yavanna and Melian and her linage.

Galadriel was also augmented by the fact that she was born in the Blessed Realm early in the Elves' history, when their power was higher.

Were they not created by the dwarves?

Feanor made the Silmarils. The Dwarves had no involvement.
