I got the Arezia Nail Polish in #690 together with a rather similar but lighter shade in #726. Both are understated enough for work yet classy.
#690 is a simpler dark brown-gold color and this is the color you get with two coats, under sunlight.
This is what it looks like under artificial lighting, after 4 days of wear with frequent hand washing. I notice that different colors have different staying power, and this is one color that lasts longer.
