Love martial arts or perhaps you've earned your black belt? Either way, adding this vintage 14K Karate/Martial Arts instructor or student to your bracelet or necklace is a must. The charm weighs 4.1 grams and measures 3/4" length x 3/4" in width. The bottom of one foot is stamped but is difficult to read; therefore, when tested with acid, the charm held at 14K. Other than the normal minor surface scratches due to time and wear, the charm is in very good condition. For a closer look, check out the pictures.
