Pre-Auction Analysis: Sotheby’s Hong-Kong October 3rd 2017

This pre-auction analysis will focus on visual elements and other observations that are not expressed on the GIA report nor in the catalog processing the images.

Important note: We strongly recommend downloading the beta version of the new FCRF app and using the auction calculator. This app lets you calculate your bidding price (per carat), including the house commission, as you follow the lot.
