Mountain Willow Studio is the creative work of Springfield artist Marty Holder, who combines timeless enameling techniques with modern design. Each piece is handcrafted with care, layering glass powder and firing it multiple times in a kiln reaching up to 1,800°F to create rich color and lasting beauty. Made in her home-based studio, Marty’s jewelry captures the perfect balance of artistry and craftsmanship—unique, heirloom-quality pieces made to be worn and treasured.
