I take all my jewelry repairs to this family-owned business in Scottsdale (camelback and miller). They do quality work with decent prices that are lower than you would expect, far more quickly than you would expect too. From restringing pearls or soldering vintage earrings, they take care of the repair.
Their jewelry is lovely and unusual too. FYI, this is not part of the Brighton chain stores selling handbags and trinkets.
And it's great to shop local!
