Jewellery Box - Conceptial Thinking

I have been struggling to find a form and idea that will combine the ideas from my jewellery, details, theorist that I like.  I will create some sketches and conceptual images to help.  I am trying to work out the form and details of the jewellery box.  A box that is not a box...
A box is...
Linear, 3Dimensional, functional, contained, portable, geometric, stationary, closed...
A box that is not a box...
No volume, no edge, no corners, blurred, no form, no function...
