Our Authenticity Promise

At North Shore Exchange, we take pride in delivering an unparalleled luxury consignment experience. Here's how we do it:



  1. In-house professional authenticators, seasoned in authenticating thousands of luxury items, examine every item brought to us.
  2. Acknowledging the reality of pre-owned items, sometimes sourced without original packaging or authentication cards, we guarantee the authenticity of each item, irrespective of these elements.
  3. If there's any suspicion of counterfeit items, we contact the consignor, requesting either a) Proof of authenticity or b) Proof of payment.



  1. Products arrive, and we conduct an evaluation for sellability and customer appeal.
  2. Items valued under $1k are authenticated and priced by our in-house jewelery authentication team, while those over $1k require an appraisal by a certified gemologist from Gem World International.
  3. Gemologists verify authenticity, establish standard pricing, and provide both retail and resale price recommendations along with a detailed appraisal.


  1. Every home and furniture item undergoes an evaluation for quality, condition, and originality.
  2. Our furniture team, well-versed in the nuances of designer home items and furniture, ensures that each piece meets our resale standards.
  3. From upholstery to woodwork, we scrutinize the details to guarantee that only exceptional and authentic home and furniture pieces find a place in our stores and warehouse.
