{"type":"firestarter.listing","listing":{"id":"lst__n1R6C1a","product_name":"Cushion Diamond Signet Ring","category":"Rings","description":"“I love this one. This is the ultimate engagement ring for a masculine person. It’s low set but still a diamond so it’s durable and tapered so you literally don’t feel it. It’s very comfy but at the same time so royal.” - AL (founder of Automic Gold)\nA signet ring for your unique signature look. When AL created this signet ring they took the beautifully inspiring cushion-cut diamond and extended its shape to the band for a stunning geometric design. The satin finish gives an elegant contrast to the sparkly diamond, and the tapered band gives the ring wear-it-everyday comfort. Rock this piece as a wedding band, engagement ring, or outfit staple.\n Ring comes with an Automic Gold ring box.\nWe can customize this ring with any design and any natural or lab-created stone. Contact us for a custom piece.\nNeed help deciding between Platinum and White Gold?
