1) Common Questions:

a) Why is there multiple sizes listed for the same ring? Cartier, Van Cleef & Arpels, CHANEL and many other well-known jewelers out of Europe use the European sizing system (EU), while Americans and many other countries use their own standard. Here at PrelovedTreasures, in each listing we will always notate the European size and the American size for reference. Also, in Europe they use the metric measuring system (typically centimeters (cm)) whereas Americans use Inches and feet. We will try to always notate both.
