Margot Van Voorhies opened her Taller after the divorce from Antonio Castillo and their successful Taller Los Castillo. This Ring has a purple stone that is a large 14mm diameter and I can say that it does not change colors. It is almost a size 8 and can be easily sized. The mounting is magnificent and is .75in. at it's widest. The design on the sides are curls that pair with so many bracelets designed by her. Properly hallmarked and with no damage what so ever. The price reflects a hard fought auction as it is highly desired and rare. I do not think there are words enough to even describe this fabulous ring!
