Built in 1868 this commercial building was built by Giacomo Ramoni using locally quarried sandstone, a year after a fire destroyed most of the block. It was first occupied by a well-known store called The Pearl of San Juan.  Notable are the iron bi-fold fire doors with a wood and glass front double door. It was one of four sandstone buildings constructed after the fire.

The building is of no particular architectural style and was built with a sandstone and wood framed structural system and concrete foundation, and the exterior is clad with sandstone blocks. There are two main entries at the front of the building, each with a granite step.

The building has been used for a variety of different businesses such as a saloon, native American Indian artwork, and various gift shops and antique stores. Today the entry located at the east side of the building leads to the courtyard of the Posada de San Juan hotel, and a shop occupies the building selling Mexican rustic style furniture and home decor.
