Abstract: In a modern society that emphasizes individuality, exquisiteness, culture and taste, emotional design thinking leads the trend of product design. As a medium for the emotional expression of designers, jewelry design brings more and more enjoyable spiritual enjoyment to the wearer, and the interesting design of jewelry is also the trend of the times. However, in a series of interesting designs, the complexity of the model and the inflexibility of the structure reduce the experience of the consumer. The childlike jewelry interacts with people with its own fun, uses geometric shapes in form, satisfies the simple aesthetic needs of modern people, gives people a simple, fashionable and modern visual experience, and at the same time gives the jewelry its own story which it can create a subtle emotion with the wearer, and thus increase the added value of jewelry. This can be highlighted in the process of designing and making jewelry with "children's interest". Combined with modern economic development and cultural heritage, the childlike jewelry can be easily resonated with modern jewelry consumers and guide the diversification of design thinking of jewelry designers and develop a broad jewelry market.
