I know the pictures can never do an item like this justice. They have to be moving to truly appreciate the way they go from blue to purple to pink and then back to blue. They are set in 14 Kt gold and are a very solid screwback setting. The stones are round and measure just under 3/8" across with the whole earring being 3/4" x 9/16". If you wish them to be converted to pierced, this can also be completed here by our certified jeweler. Please call our toll free for details.
