Beginning with a classic screen, the one above from thebellacottage.com gives an antique feel with its subtle and muted colors and raw textures. Fairly reasonable, the Darling Screen goes for $1095.
For a more extravagant feel, the screen below from laylagrayce.com catches the light and opens the space with its beautifully buttoned antiqued mirrors and its gold (or silver) leaf finish. It's beauty, however, does not come cheaply. The three panel mirrored screen is listed for $3900.
Just because we are working our way up the totem pole, I have to continue with an Oly creation. Found at shopcandelabra.com, the four panel screen below is constructed of a metal frame with again your choice of gold or silver detailing. What makes this screen so inspirational is the lace-like qualities of the capiz shells, that allow light to pass through in a soft and delicate manner, illuminating the piece. Price is given upon request. I dare not request.
For a slight switch in focus, a more economic and creative solution to separating space can be done in the Mio fashion. Found at allmodern.com, the Mio Culture Nomad Architectural System is made of recycled double-walled cardboard pieces (nine colors available) that can be fitted together in an open or closed fashion, giving the buyer control of size, shape and pattern. Pricing begins at $56 for 24 modules , which creates a 4.5' square open screen or a 3' by 4.5' closed screen.
