Let's start with the packaging. A lot of people do not like NARS packaging; it has a matte black case that flips up with a mirror inside. I actually think it looks sleek and sophisticated. I really like the packaging; it hasn't proven difficult for me so far.
Though it is a very beautiful gold, the color is not unique. I have a lot of golds that look very similiar to this. I will soon swatch all of my gold eyeshadows so you can see the difference of them all, but the good thing about this eyeshadow is that there is no glitter in this color, so it is a 'grown-up' gold.
The texture is buttery, but I have used softer eyeshadows, particulary some of Stila's eyeshadows. I do wish Etrusque was more pigmented; I feel like I have to pack it on somewhat to get decent color pay-off.
If you are looking for a more sheer gold that you can build up to more color, then this eyeshadow is for you. I do believe you can find a similar gold that is less expensive, though. This is an eyeshadow you may have to try for yourself, or go to your local Sephora to swatch, because some people love it, and some people hate it, and I am kind of neutral about it.
