$124, deskohan.com

My twin sister, who is a mother to two young children (not coincidentally, the same ages as mine!), has been longing for a signet ring. So for Mother's Day, I got her this one by Bare from Des Kohan. The teardrop shape gives it a modern twist, and it can be monogrammed with one to three letters (I thought it'd be cute to do the first initials of both of her kids). It comes in white, yellow and rose (my favorite) gold and costs $124, plus engraving. I like the idea of wearing it as a pinky ring. She will love it too.
