Client Reviews

  • KATIE HELPED ME MAKE DECISIONS ABOUT THE RING SO THAT IT WOULD FIT BEST IN EVERY WAY. STYLE WISE, I WANTED IT TO BE THIN BETWEEN MY FINGERS FOR COMFORT, AND UNIQUE YET STILL CLASSIC. ON TOP OF THAT, THIS RING IS ABOUT LOVE, AND FRIENDSHIP, AND CELEBRATING PEOPLE AS THEY ARE. I HIGHLY RECOMMEND KATIE. SHE LEARNED ABOUT ME AND CREATED A PIECE THAT WAS TRULY SIGNIFICANT TO ME AND HONORED MY STORY. SHE MAKES WEARABLE ART.

  • KATHERINE'S SERVICE AND JEWELRY ARE BOTH IMPECCABLE. I ORDERED A PAIR OF HER GOLD GEOMETRIC HOOPS FOR MYSELF AND MY FRIEND LOVED THEM SO MUCH, I GAVE THEM TO HER FOR HER BIRTHDAY AND AM ORDERING ANOTHER PAIR FOR MYSELF AND ANOTHER FRIEND WHO ALSO LOVED THEM. THEY ARE A CLASSIC, CLASSY DESIGN THAT CAN BE WORN EVERYDAY OR FOR A SPECIAL OCCASION BUT THEY'RE ALSO SO UNIQUE AND MORE SNAPPY THAN A TYPICAL HOOP :) JUST LOVE HER WORK!

  • KATIE WAS SO FUN AND EASY TO WORK WITH! SHE BROUGHT MY VISION TO LIFE AND CREATED A TIMELESS WEDDING BAND WITH SAPPHIRES AND A DIAMOND THAT I CHERISH EVERY DAY. SHE COMMUNICATED WELL THROUGH THE PROCESS EVEN THOUGH WE ARE IN DIFFERENT STATES. I'M TRULY THANKFUL FOR HER CREATIVITY AND TALENTS!
