Expedited Authentication
Sisley Experts understand the needs for expedited authentication due to strict return deadlines or if you are in need of pre-purchase authentication. While most foundations can not provide authentication within 7-14 days, Sisley Experts can provide authentication within a short turnaround time due to our extensive team of experts and resources. If you have recently bought a piece and have a short window of return, or are looking to purchase a piece and would like it authenticated before the sale, we realize time is of the essence and can provide the necessary information to assure you of the integrity of your purchase.
