Pre-Auction Analysis: May 11, 2022, Christie’s Geneva – Magnificent Jewels

Our Christie’s Geneva Pre-Auction Analysis focuses on elements that aren’t visible to the untrained eye. We describe important visual elements for those who cannot attend the preview. We discuss characteristics such as: Undertone, Color Dispersion, and Inner-Grade, collectively termed IDU. These visual assets are explained in detail at the end of this article.

It is important to note that 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 IDU score of 9, 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 jewelers and collectors.

For your convenience, we have added direct links to the GIA reports.
