Marc Jacobs Beauty Glitter Rock is a very cool-toned, dark silver with a glitter finish. It is a limited edition eyeshadow that retails for $28.00 and contains 0.12 oz.
Marc Jacobs Beauty Glitter Rock See-quins Glam Glitter Eyeshadow ($28.00 for 0.12 oz.) has a darker, gray base with subtle, cool undertones packed with a ton of silver shimmer and glitter. It had nearly opaque pigmentation applied dry and had full coverage when applied with a wet brush. The texture was loosely-pressed, slightly drier and chunkier, so there was some fallout during application when I used it dry. To minimize fallout and ensure a smoother application, I'd highly recommend using it with a dampened brush. This shade stayed on well for eight and a half hours and had light fallout over time.
Note: The ingredient list shows Polyethylene Terephthalate (PET glitter) as an ingredient, but there were no warnings on the box nor on the product listing. It turns out that some of the previously released shades also include Polyethylene Terephthalate. The product is marketed for eyes, and it is called eyeshadow. Typically, products containing Polyethylene Terephthalate often come with a warning that they are "not intended for use around the immediate eye area" (like ColourPop Pressed Glitters), but there have been an increasing number of instances where brands include it and market those products for eyes specifically (like Urban Decay Heavy Metal Glitter Gels and Glossier Play Glitter Gelees).
