Brides to be rejoice! Monique Lhuillier, the designer who has created wedding gowns for so many celebrities including Ginnifer Goodwin, Stacy Keibler, Reese Witherspoon, and Glee star Naya Rivera (who tied the knot just a few days ago), has launched an engagement ring collection. As glamourous as her sensational dresses, the rings feature fresh silhouettes decked out in diamonds. There are sapphire options. All the styles are set in platinum. Lhuillier took the time to answer all our questions about the gorgeous rings—get the details below.

What inspired you to design engagement rings?
It was a natural step. Without the ring there would be no dress!

Several pieces in your collection have unique silhouettes like the Art Deco Halo ring and the Hexagon Halo Ring. Were these pieces inspired by dresses in your collection?
I often draw inspiration from my dresses when I design my jewelry collection. In this past bridal collection I experimented with color, specifically using a beautiful hydrangea blue. Then I introduced a blue sapphire into this new jewelry collection for fall. I offered the sapphire jewelry for my bride who is less traditional and wants to make an impact on her big day.

How is designing engagement rings different than wedding gowns?
The design process whether its dresses, engagement rings or my tabletop collection simply starts from something that visually inspires like a beautiful fabric, work of art or a bold color.

Your engagement ring collection is sold exclusively on bluenile.com, where brides and grooms can participate in the design process by choosing their own diamond in the exact size, color, cut and clarity they want to go in the setting you create. What do you like about Blue Nile?
I love the idea of a custom designed engagement ring. I found more often that grooms and couples want to add their special touch to their engagement ring and bluenile.com provides their customers with fine quality, value, and guidance through an extremely easy and personally tailored experience.

Your new collection of engagement rings is made in platinum exclusively. Why do you think the metal is the right choice for brides?
Platinum is a great choice for engagement rings and wedding bands because it is naturally white so it won’t change color or fade. It symbolizes a relationship that will endure. Platinum’s strength and durability makes it the most secure setting for diamonds and precious gemstones, meaning your diamonds and gemstones will be safe.
