You list is all "stone" products. Stone products are natural. The durability is guaranteed with stone. Stain resistant...remove marble and granite from your list. Both can stain and etch and both will do this with "flooring" more than they will with a counter top. Gloss levels all change...but it will take years to do it. All stones have maintenance = homeowner needs to work at keeping stone looking good. Stone = expensive. There is no "benefit" for "reasonable" when working with stone. They all cost plenty of money. Stone is expensive. No way around it. If you want "glossy" that doesn't stain for a "good price" then you have forgotten to mention the BEST option: porcelain tiles. Porcelain will do everything you want for a lower price. Stone is expensive, it can stain (especially "oil" stains) it will "etch" or lose gloss level with certain liquids (acid based liquids will do this) and they all need to be maintained and eventually need repolishing to maintain "gloss". Durable is all you can expect out of stone. The rest of your wish list belongs with porcelain tiles.

you could always use any glass top table with steel frame and put a matt finished steel tray arranged with some metallic miniatures or candle stand or spray paint some wooden table with metallic paint and give an oxidised look.

Hello, I feel that you can design this bedroom by having 1 opaque wall at the back, and 3 transparent walls using glass & steel or glass & wooden french doors. The walls should be white, with minimal accents of blue or green, use 2 layers of curtains with sheer, and brass hanging lamps. All doors can be white PU paint. Waterproofing this bedroom will be essential, so make sure you have sealed all joints and surfaces, with a minimum of 2 feet roof overhangs. Hope this helps! G

good work :)
