They passed their knowledge and refined their skills over five generations, the Aletto Brothers name stands for excellent craftsmanship and quality. Still family owned and operated, the firm is currently based in Boca Raton, Florida, but was originally started in Naples, Italy, by Bartolomeo Aletto an Italian goldsmith.
