Just wanted to send you a note to let you know that everything turned out wonderfully! We just got home from a week-long trip to the Maine...where, in addition to spending time with family, we spent several days kayaking between a number of small islands along the coast. Armed with an elaborate drybag setup to strap the ring to me as well as a good insurance policy (thanks for the reminder!), I'm happy to report that the ring made the trip safely...and that the weather cooperated to make for a beautiful sunset proposal with a nice bottle of wine on a tiny isolated island with 360-degree views of the Maine coast. My girlfriend-now-fiancee absolutely loves the ring...and we're finding that the brilliance of the ACA stone is really quite amazing!
Thank you again for all your help in this process! ...we may need to come back to you for advice on wedding bands... =)
