Acetate pearl ring

When I saw this ring on the web site, I instantly wanted it because of the colors -- two of my favorites! But I hesitated for a bit because I wasn't sure about the sizing. Years ago, I could purchase my size with perfect confidence; however, lately JCrew rings in what should be my size seem to be fitting a bit tight. I ordered this ring in my usual size anyway, and to my delight, it fits perfectly, neither loose nor snug.
