Sotheby’s New York, Important Jewels, March 9, 2022

 

We are happy to bring  you our Sotheby’s Pre-Auction Analysis. We hope it will help those who would like to participate in the auction without physically inspecting the goods.                                                 

Our Sotheby’s New York Pre-Auction Analysis focuses on elements that aren’t visible to the untrained eye. We will describe the important visual elements for those unable to 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 grade.

We use grades 1, 2, 3, and 4, with 1 being the lowest grade. A grade of “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.
