Changing the meaning of Luxury

Going through the list of links to different galleries and artists, one link finally got my attention: By:Amt, a company founded by Alissia Melka-Teichroew. The first work I saw from their website, was the Inside Out Glasses, which were a series of beverage containers that had the form of the wine/martini/champagne glass on the inside while the outside silhouette is a basic, simple tapered cylinder. When filled with a liquid, the shape inside shows much more clearly, creating a contemporary and engaging piece of art, seeming as if the drinks are floating in space, creating in space the shape of the vessel it is supposed to be in.
All her works, allow us to see quite ordinary objects in a very different way. She makes diamond rings just a beautiful (or more beautiful in my opinion) as the tiffany-set diamond ring, without the diamonds, made out of acrylic, silver or gold. Or the 3D Silhouettes of a series of life-sized Victorian era furniture, made just from painted pieces of mdf that allows people to rearrange their “furniture” everyday, changing the scenery at home without the strenuous task of actually moving real furniture.
Another designer I found on the list of links was Tobias Wong. He seems to be trying to do what Alissia Melka-Teichroew is doing; to change what “luxury” means, but in a very different, and quite opposite way. While By:Amt appreciates what the current norm of a luxurious item is (using expensive, rare materials). She uses this to introduce another way of seeing luxury; using normal/non-luxurious materials such as plastic and making them into a seemingly luxurious, expensive piece of jewelry. Tobias criticizes the current definition of luxury (“bling bling!”). He uses what is already a luxurious and expensive item (a crystal chandelier) and covers it with a normal/non-luxurious material (industrial rubber), making it seem less valuable.
I think that the current definition (of most people in 1st world countries) of “luxury” is overrated, and shouldn’t mean covering yourself in designer clothing and precious metals and diamonds. And although both By:Amt and Tobias Wong are commenting on this idea of “luxury”, I personally think Alissia Melka-Teichroew has been more successful.
