This gorgeous engagement ring by Kristin Coffin reminds us of a snowflake, so how perfect is it to share this month with the advent of the winter season? This beauty is available in recycled 14k yellow, white or rose gold, with a 7mm Charles & Colvard Moissanite center. Our favorite part is the oval shaped halo which has a third carat of Canadian diamonds in varying sizes. Scroll down to see the stones set in each metal. It's hard to choose a favorite isn't it?
