It looks like the May (I didn’t actually check so I’m guessing) edition of Marie Claire has one of two possible Ciate Nail colours as a free gift.
Choices appear to be a metallic gold or metallic pink. Inside there is a code for 20% off Ciate orders.
EDIT – Claire over at Kerruticles has swatches of both of these on a nail wheel. You can check them out by visiting her blog here
EDIT – SpecialGirl Nails has swatches of the gold shade (Sand Dune) that you can see by visiting her blog here
