I'm downright scared to wash my Burgundy glasses! I use the Riedel Sommelier Burgundy glasses. They are quite thin indeed! The Lalique wine glasses are thicker, feel more substantial, and I'm much more confident to clean them. Back to watches and gems, I found Brandon.c's post comparing two types of gem-set watches; some watches benefit from an "upgrade" and some watches truly becoming a "transformational" piece to be another interesting comparison. More food for thought!
