Wow! Isn't this cool?! I found Keely on Etsy some months ago and forgot to put her on here. The pendants are made of stacked glass which she has cut and hand ground to make those smooth buffed edges. A young artist, Keely has already won awards for her work. Here is a clip from her Etsy Bio,
"I am Keely Beth, a full time college student for another year, and a lover of art, jewelry, and anything handmade! For years I have wanted to find a way to combine my love of art and jewelry making, and KeelyB is the result."
