This knob is both beautiful and unique! The quality is excellent. Even so, when you look closely at the clear glass, you can see and feel little lines in it (it is not perfectly smooth). This probably would not be visible on the frosted ones. Unfortunately, this knob will not work in our room. In the picture, it looks like a seafoam green - perfect for our bath. In actuality, it has a lot more yellow in it - more like a lime green. Also, the 1.75" projection is greater than our countertop overhang, so when we stand and lean into the sink, it pokes us.
Tips for buying such things on the internet:
The photos can be deceiving - Pay close attention to the dimensions given and the space where you will install it.
To be sure that the finish/color will work in your space, DO allow time to order just one knob as a sample, since these folks won't accept a return if you order more than 10 of them (So, would anyone like to buy 19 of these from me???)

Cool hardware but color is GREEN not blue green as pictured

Love the knobs. They are beautiful. One problem - the color is very different than pictured. I know the description says green, but there are lots and lots of shades of green. The picture appears to be aqua green. But not. In real life the color is a true grass green, a primary color, and definitely NOT an aqua or muted shade. I'm very disappointed, but can only blame myself. I should have called and talked with someone before I ordered. Bummer.

I ordered both the acorn shape and the mushroom shape in the same color (amber) to see which one I preferred - loved them both. I ended up going with the mushroom shape because they did not stick out as much which was important in some tight areas in my kitchen. I also used the coordinating bin pulls for the drawers. All are of excellent quality. The order arrived EXTREMELY fast, which was a bonus.
