Dark Blue Duodecimal Square Band - textured
This sweet, simple band has twelve 1mm dark blue sapphires set equidistantly around its circumference. It is named after the 12 base numerical system which has been used within different cultures for thousands of years, measuring units of time, weight and distance.
This band is 1.3mm wide and can be used as a wedding band to sit beside our other rings, works well in a ring stack, and also looks great worn on its own.
Handmade in recycled 18ct gold with a heavily textured finish. Sapphire is the September birthstone.
Please allow 6-8 weeks delivery time.
