In which era did moonstone lose its popularity?

Moonstone's decline in popularity is closely associated with the Art Deco era, which spanned the 1920s to the 1930s. During this period, jewelry design underwent a significant transformation characterized by geometric shapes, bold colors, and the use of materials such as platinum and diamonds. Art Deco embraced modernism and often focused on a streamlined aesthetic, which favored more opaque stones and synthetic materials, leading to a reduced interest in the softer, ethereal qualities of moonstone that were more celebrated in previous design styles.

In contrast, both the Victorian and Edwardian eras showcased jewelry with romantic and naturalistic themes, where moonstone was frequently appreciated for its unique adularescence and mystical qualities. As for the Modern era, the popularity of moonstone has seen a resurgence as contemporary design often draws from historical influences, including the fascination with gemstones that exhibit unique optical phenomena. Thus, the transition in popular style during the Art Deco period is what primarily impacted moonstone's status in the world of jewelry.
