Pre-Auction Analysis: November 27th, 2021, PHILLIPS Hong Kong

This is our first Phillips Pre-Auction Analysis, and we hope you find it useful. Due to COVID restrictions, Hong-Kong is still closed to visitors. This Auction Analysis could help those who would like to bid in the upcoming Phillips auction without physically inspecting the goods.                                                 

Our Phillips 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 bottom of this article. We analyze and grade Fancy Color Diamonds relative to their GIA grade.

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.
