Lifetime Professional Diamond Service

When you purchase an engagement ring with us, you become a valued member of the Black Diamonds- New York family. We pride ourselves in providing continuous premium service after the warranty expires, including care and repair, complimentary ring polishing, and a full lifetime diamond service. Replacing missing stones will be up for quotation depending on the total carat.

  • Silver/Gold polishing
  • Professional cleaning
  • Lifetime Diamond Service
  • Plating maintenance depending on your order

While we offer a full-year warranty (which means fixing rings when needed), what we cannot control is how people treat their rings, and thus we cannot guarantee how long rings will stay clean, how long the black and rhodium plating will last, and/or if they ever break. We stand by our lifetime professional service, and if you ever need your ring professionally polished or refinished again, please let us know.

Please contact our team on how to ship your item back. Note that we don't cover shipping fees for this service so you will have to pay for shipping back and forth.
