Royal Blue Sapphires

Blue must be my favorite color.  I know this because I am drawn to the finest blue gems and most of the designer jewelry I’ve made are in the shades of blue.  Here are two examples of the best.

Modern Art Deco Earrings & Pendant

I created this pendant and earrings in my favorite monochromatic color of the blue Aquamarines.  When my stone cutters from Idar-Oberstein, Germany showed me the parcel of the blues I just had to buy them all!  Perfectly cut and flawless, they sparkle and when put together exhibit a soft blue glimmer that can be worn with everything from evening to day to late-night.  Mixed with white Diamonds set in 18k, they are one of a kind fine jewelry and totally chic.

And, who doesn’t LOVE Art Deco?  I am inspired from the designs of the Art Deco period–clean, simple lines that are curvilinear depicting the fluidity of movement.
