The garland will surprise you with it's impact. I love both... you have a lot of very classic pieces, so I think either will work for you. But I vote for the garland.
Thank you all for your votes and comments. You have helped me decide on getting same size stones for my huggies. I guess it is the clean (elegant) look that speaks to me more. The only change from the original consideration is that now I am thinking about ten 30-33 pt stones.
15 pt size stones look too small to me. I confirmed this assessment by placing 15-pt melees from my eternity ring and tennis bracelets next to the 20-pt huggies (ones in photo, belong to my sister). The 20-pt size looks great, but 30-pt size is even better, especially when they are ACA's.
