Pre-Auction Analysis: April 13, 2022, Christie’s New York, Magnificent Jewels Including the Fuchsia Rose Diamond

Our Christie’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 who cannot attend the preview and discuss characteristics such as Undertone, Color Dispersion, and Inner-Grade. These factors, collectively termed IDU, 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.
