Sotheby’s Hong Kong, Important Jewels February 18, 2022

As most of the industry has been unable to travel to Hong Kong during this challenging period, this auction analysis can help those who wish to bid without physically inspecting the goods.
Our Sotheby’s Hong Kong Pre-Auction Analysis focuses on elements that aren’t visible to the untrained eye. We will describe the important visual elements for those who cannot attend the preview and discuss characteristics such as Undertone, Color Dispersion, and Inner-Grade. These factors, collectively termed UDI, are explained in detail at the end of this article. We analyze and grade Fancy Color Diamonds relative to their GIA grades.
We use grades 1, 2, 3, and 4, with 1 being the lowest grade. Grade “4+” is granted in rare cases and denotes stones with exceptional characteristics. Stones that receive a minimum total UDI score of 8, without a red remark, pass the industry threshold and can be traded easily. Fancy Color Diamonds that are graded 10 or above, (without a quality remark) are usually sought after by high-end jewelry brands, collectors, and the investment community.
For your convenience, we have added direct links to the GIA reports.
