This wide “Borealis” ring comes complete with a handpicked suite of heated sapphires and natural diamonds. There are 43 heated Montana sapphires, cut to high precision and selected for excellent clarity, weighing an approximate total of 5.20 carats. They were mined from the famed alluvial deposits along Rock Creek near Philipsburg, Montana. The color was developed by heating the sapphire in Montana, but no other treatments were used. The treatment is permanent and stable and not only develops the color, but also improves the clarity. There are also 36 tiny diamonds, all with G+ color and VS clarity, weighing an approximate total of 0.24 carats. This style features a micro pave-set top with a hidden sun-shaped detail underneath.

This “Borealis” ring is made from 18k white gold in a ring size 6.75, and cannot be resized. If you are used to wearing a narrow size 6.75 ring, this ring will fit tighter due to the width.

All rings are delivered in a custom wooden gift box and a lifetime warranty against any manufacturing defect. Ready-to-wear jewelry is subject to our standard returns policy; please see the full returns policy for more details. If you have any questions or special requests, please contact us.
