A replica of Cersei's Crown. It's 18.57 x 7.782 x 21.058cm respectively 7.311 x 3.064 x 8.291 inches large.
If you intend to wear this crown, I strongly suggest to have it printed in "Strong and flexible" plastic, then either paint it or use leaf silver and gold to create the metallic appearance. If you intend to just paint and display it, I suggest using the Frosted Ultra Detail material.
A matching ring is available here in sizes 2-13
