Do they fix broken necklaces?? Also, is it a same day service, or do they send out to be fixed??

I believe they do all of their own work in house. They are expensive.

Yes, absolutely fix jewelry... I prefer Estate Jewelers... Cheaper and actually offered a used necklace that was half the price. Cheaper than fixing my necklace.

Yes

I believe that they do any repairs in their own workshop on premises
