This is a ready to ship niobium septum spike, you will receive the exact piece in the photo.
This piece is 2.5mm in size with a 39.75mm length. It is solid niobium and it has been anodized by hand to have a rainbow gradient, from green on the tips to yellow/high polish in the centre, please note that as this has been done by hand the gradient is not perfectly even on both sides.
