Sotheby’s Hong Kong, Magnificent Jewels, October 12th, 2021
As most of the industry has been prevented from traveling to Hong Kong during this challenging period, this Auction Analysis could help those who would like to bid without physically inspecting the goods.
Our Sotheby’s Hong Kong Pre-Auction Analysis focuses on elements that are hidden from the unprofessional 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 (UDI; a detailed explanation appears at the bottom of this article). We analyze and grade Fancy Color Diamonds relative to their GIA grade.
We use grades 1, 2, 3, and 4, 1 being the lowest grade. Grade “+” is granted in rare cases and stands for stones with an exceptional characteristic. 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 for the GIA reports.
