This research probes into the influence of sustainable jewelry design on lifestyle brands, green lifestyles, and product quality. Through the lens of multidisciplinary analysis, the study reveals the intricate relationships between these variables and provides a robust theoretical foundation for their interplay. Applying an advanced statistical modeling technique, Structural Equation Modeling (SEM), we explore the complex, direct or indirect causal relationships among the variables. The study uses sustainable jewelry design, green lifestyle, lifestyle brands, and product quality as latent variables, revealing their interconnections through a theoretical model built upon previous research assumptions. The findings indicate a significant positive impact of sustainable jewelry design on lifestyle brands and green lifestyles, advocating the importance of such designs in transforming consumer lifestyles and brand choices. However, the anticipated direct influence of sustainable jewelry design on product quality was not as substantial, suggesting further exploration in this dimension. This research contributes to the existing literature by providing a comprehensive understanding of the influence of sustainable jewelry design on lifestyle brands, green lifestyle, and product quality. It offers valuable strategic insights for jewelry brands and advances the broader discourse on sustainable production and consumption, thereby underscoring the value of a multidisciplinary approach in understanding consumer behavior and brand strategy.
