Pre-Auction Analysis: Magnificent Jewels Christie’s Nov 14 and Sotheby’s Nov 15 Geneva 2017
This pre-auction analysis will focus on visual elements and other observations that are not expressed on the GIA report nor in the catalog. Our analysis expresses characteristics such as Undertone, Color Dispersion, and Inner-Grade (UDI). We use grades 1, 2, 3, and 4 (grade 1 is the lowest grade).
The grade 4+ is granted in rare cases and stands for an exceptional characteristic. Stones that receive a total UDI score of 8 or above (SI1 or better) are considered to be gems and are probably suitable for high-end jewelry, collectors, and the investment community.
For your convenience, we have added direct links for the GIA reports and for the FCRF Rarity reports.

A fancy intense pink old mine pear shape cut with a very noticeable black inclusion underneath the crown and a penetrating feather from the girdle inside (hidden under one of the gold prongs). The inner-grade is low and receives the grade 1, which means it’s borderline being a fancy pink.
