Giorgio Armani #17 is a neutral-toned, light silver with a metallic finish. It is a discontinued eyeshadow that retails for $33.00 and contains 0.14 oz.
Giorgio Armani #17 Eyes to Kill Intense Eyeshadow ($32.00 for 0.14 oz.) is a silvered gray with darker gray sparkle. I was worried that it would resemble #12 too much, and while they're similar (and unless you wear a lot of silver, you don't need both), they're not dupes. #12 is bluer, lighter, and much more metallic (go figure), while #17 is more neutral and gray with a subtler silver sheen and shimmer. It almost looks pink-tinted in comparison. MAC Misty was the closest shade I could think of, but it's pinker and lighter.
