First off, these are sterling from top to bottom, from the accents, pins, and through to the ear wires. Sterling gets patina--that gray cast, versus the shiny cast. You can rub the patina off if you don't like it! Your own skin oils will wipe them away on their own, but... that's by design. Sterling tarnishes. If shiny metal is a must have, there are sterling polishing cloths out there.
Becky's paired the sterling with hand-crafted lampwork beads in blue. The color is a summer sky, and the accents top and bottom are ab finish crystal.
End result: gawj.
