Our Authenticity Guarantee

We work with a range of trusted, prestigious sellers worldwide who are respected experts in their fields and stand behind the authenticity of each item available for purchase on our website. We offer our Authenticity Guarantee to address concerns regarding authenticity made within one year of purchase. Subject to the terms below, if an item purchased from us is found to be inauthentic, our Authenticity Guarantee will provide up to $100,000 to reimburse the purchase price and related shipping expenses for the item.

Our Authenticity Guarantee applies to the following attributes regarding items purchased from our website:

  • Creator: We guarantee the identity of the specific creator, brand, designer, manufacturer, or artist indicated on the item listing page. Note that the our Authenticity Guarantee does not apply to items described as “attributed to,” “circle of,” “in the style of,” or “after” a specific creator in the Item Details, as such designations signify that the item is not necessarily produced by the creator identified in the listing.
  • Material: We guarantee that the item is made of genuine materials to the extent described on the item listing page, including, as applicable, the material; metal; stone; stone cut, color and clarity; weight (carat related to jewelry stone and ounce related to silver) and medium of construction set forth on the item listing page.
  • Time Period: We guarantee that the item was manufactured in the period, date of manufacture, or creation year indicated on the item listing page. Note that for items with approximate dates of manufacture or creation years on the item listing page (“circa” dates), our Authenticity Guarantee only applies with respect to such attributes if an item is found to be manufactured or created in a materially different period than such approximate date indicated on the item listing page.
  • Technique: We guarantee that the original methods of construction described on the item listing page are accurate. Our Guarantee covers technique as it relates to the craftsman’s original work and does not cover modifications of the item over time.

Our Authenticity Guarantee is limited to the attributes listed above and does not apply to the following attributes (which list may be amended from time to time at the sole discretion): Place of Origin, Condition, Movement, Style, Size, Case Shape, Dimensions and Case Dimensions. However, you may contact us to report concerns related to these or any other attributes under our Buyer Protection policy.

To be eligible for payment under the Authenticity Guarantee, a Buyer must:

  • Have completed the order through our secure checkout
  • Contact us within one year of the order confirmation date of the item
  • Provide within one year of the delivery date of the item written opinions from two (2) independent and recognized experts in the field substantiating the claim of inauthenticity. Note that in limited circumstances, we may in our sole discretion waive the requirement of a second independent substantiation based on the identity of the initial expert provided.
  • Provide us with any additional supporting documentation that may be reasonably requested by to facilitate the determination of its assessment of the claim
  • Return the item in the same condition it was in at the time of purchase on our website.

Once a Buyer contacts and provides the required supporting documentation, we will examine the claim internally and with the Seller. The Seller will have the opportunity to provide one or more written opinions from independent and recognized experts in the field to refute the inauthenticity claim. Ultimately, we shall have the sole right to determine the validity of any inauthenticity claim and whether our Authenticity Guarantee program will reimburse the Buyer for the following costs:

  • Original purchase price (inclusive of taxes and duties paid by Buyer)
  • Original shipping
  • Return shipping
  • Reasonable and customary fees paid to the two substantiating experts for their written opinions

Submission of expert opinions or other substantiation is not dispositive and does not require us to accept a claim under this policy. Our determinations, including as to authenticity and the associated costs to be reimbursed, shall be final in the absence of our manifest error.


We reserve the right to amend any of the provisions of this Authenticity Guarantee at any time in its sole discretion and without further notice. Any changes will be effective upon the posting of such changes on the Site.
