X and I have been looking for either sapphire or emerald solitaires in a platinum setting. Surprisingly, http://www.bluenile.com/ doesn't have a great selection of non-diamond engagement rings. But, it is a good starting point for picking out the specs for your ring. And, they are having a sweepstakes to win a diamond valued at $5,000 when you visit the site.
X and his sister went jewelry shopping this past Saturday. It was to be a surprise, but he was so impressed by one of the stores that he thought we should shop together at Green Lake Jewelry Works.
