SpaRitual Conglomerate Nail Lacquer ($10.00 for 0.50 fl. oz.) is described as a “charcoal rock glitter infused with rhyolite.” This has a murky gray base with olive green shimmer and circular black and light gray flecks. It’s the mixture of shimmer and glitter that makes this unlike other polish I own. I don’t even know of what I could mix that would yield this result, even if I layered products. I’d love to hear any possible dupes if you’ve come across anything!
