Despite making jewellery, I still appreciate and buy other jewels. A few years ago, I picked up this AMT acrylic "diamond ring" from the MoMA Store in NYC. I have the opaque creamy colour on the left. It's purdy funny, especially when stacked with real rings! They come in the colours above as well as in silver and gold. There's also a "pearl ring" version.
These USB "keys" are new, so I'm going to be on the lookout for one of these. Go to their site HERE for more of AMT's smart work.
