After a ruling in Geneva in 1556, what alternative products did goldsmiths begin to create?

The correct answer focuses on the historical context surrounding the Geneva ruling in 1556, which significantly impacted goldsmiths' practices. Following this ruling, goldsmiths began to diversify their craft, responding to changes in demand and market conditions. Specifically, they started creating silver cutlery, which aligned with the growing trend of using silver for functional household items.

This transition was influenced by the era's social and economic factors that drove innovation among artisans, prompting them to explore materials and products that would appeal to consumers. The creation of silver cutlery allowed goldsmiths to maintain their craftsmanship while adapting to a more viable market segment that extended beyond traditional gold items.

While wristwatch mechanisms and luminescent dials are associated with different technological advances in horology and jewelry design, these developments occurred long after the 16th century. Precious gemstones, while valuable, did not emerge as a primary product from goldsmiths following the Geneva ruling; instead, the focus was on functional silver items like cutlery.
