Pre-Auction Analysis: NY Magnificent Jewels, Sotheby’s December 4th, Christie’s December 5th, 2018

Our Pre-Auction Analysis focuses on elements that are hidden from the non-professional eye. As always, we will describe the important visual elements for those who cannot attend the preview. We will discuss characteristics such as Undertone, Color Dispersion, and Inner-Grade (UDI; a detailed explanation appears at the bottom of this article).

We use grades 1, 2, 3, and 4, (1 being the lowest grade). Grade 4+ 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 remark, are considered to be “Gems” and are mostly suitable for high-end jewelry, collectors and the investment community.

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