While Alexis Bledel, and on screen Mad Men lover, Vincent Kartheiser have been engaged since March we’ve been waiting with bated breath for the reveal of the engagement ring. And it was definitely worth the wait. The ring is a gorgeous octagonal diamond set on a simple platinum band with a bit of a vintage air.

The look is incredible; the octagonal shaped diamond really adds interest to a simple band. But if perhaps you had your heart set on a princess or cushion cut diamond NK27063-18W is an equally stunning engagement ring. Like all of the rings in the Renaissance Collection NK27063-18W has the same vintage styling of Alexis’ diamond ring. The square halo with deep cut corners has a similar octagonal shape as well as the benefit of added sparkle and the size amplifying effect of a halo.

Or if you love the bold geometric punch, but prefer something more modern, NK26336-W is perfect. The clean lines of this engagement ring’s hexagonal halo offers the versatility of a linear diamond frame around what could be a brilliant round center stone.
