The first drawing shows different studies for a bracelet, with green stones—likely emeralds—as the highlight, interspersed with decorative elements in shades of gray representing diamonds and gold or platinum structures. The variations range from more rigid geometric shapes to more elaborate and almost floral ornaments, revealing a search for balance between elegance and complexity. Small technical sketches of clasps and calculations of measurements and carats, accompanied by notes in German, reinforce that this is a functional project, aimed at the actual execution of the jewel.

The second drawing depicts a necklace approximately 40 cm long, with rectangular green stones along the chain and a central oval-shaped pendant, surrounded by a halo of diamonds. The composition prioritizes symmetry and harmony between the gems, creating a piece of great visual impact. The notes written in German indicate weights, dimensions, and assembly alternatives, showing a detailed study before production.

These drawings appear to belong to the context of European high-jewelry workshops, likely German ones from the late 19th or early 20th centuries, a period when it was common to document projects in watercolor and graphite. Although the author is unidentified, the technical and refined style suggests an environment close to renowned houses in the German-speaking region. Beyond their aesthetic value, these documents possess historical importance, as they bear witness to the creative and artisanal process of luxury jewelry of the time.
