Because we love to make them this way... and I love the Blue Diamonds... We made the Starseed Earrings (which are about my favorite right now!) with the blue diamonds. The gold and the blue is just so lovely together, I'm pretty sure it will be your favorite too! 
The diameter of the earring is 5mm, and is set on a 14k French wire, with a clear back. The diamonds are 1.3mm, blue, conflict free, brilliant cut.
