Materials used to create this particular stone are Archival Ink applied through different methods including but not limited to pen tip ranging in size from .005-.03 a calligraphy tip and ink well and even a toothpick when necessary... It also includes love light with a dash of magic. Each stone is hand picked for its size and texture, then properly prepared before the piece can come to life. I also sign and number each stone for authenticity.... Thank you so much for your interest in my passion.
