Obsessive Compulsive Cosmetics Ripley Nail Lacquer ($10.00 for 0.50 fl. 0z.) is described as a "blackened, antique olive-gold [with a metallic finish]." At a glance, it's exactly what comes to my mind when I think of "black gold." More descriptively, it's a blackened olive base with golden olive green shimmer with a metallic finish. China Glaze Agro is slightly greener, not as metallic (smaller shimmer). Cult Nails in a Trance is less blackened, more shimmered than metallic. NARS Mash is much greener.
