Congratulations! What a beautiful ring.
Enjoy your engagement, it's a special time for a couple.
sidenote: For a great wedding planning website, may I suggest www.weddingchannel.com? They have great message boards (as Jill1228 and jh124 will also attest to). I've been there for two years and don't plan on leaving anytime soon, though I've been married for almost 6 months.
