This Turquoise Catus Ring is designed in 3D modeling software. We then 3D print the design in a castable wax resin. Then we cast it using the lost wax casting method. Metal can tarnish over time. We recommend using a flannel polishing cloth to clean the jewelry. Your jewelry will come packaged in a handmade bag, perfect as gift wrap and for storage. As each piece is handmade to order, please allow approximately 10 days for your order to process and ship. This gorgeous piece is stunning, I wear it daily. Please check out our store for more pieces. We have an ever-growing variety of pendants, earrings, rings, bracelets, cufflinks, and belt buckles. Thank you!
