The biggest question I have is which inclusion is the least one to give me trouble down the road. I have heard feathers are not the best but it depends on where they are in the stone. And crystals depend on color. What about a twinning wisp, i heard these are not noticeable to the naked eye. So I am looking at DSI1 with crystal, an ESI1 with crystal and feather, and ESI1 with a twining wisp
