Jewelry display case customization prices are usually affected by a number of factors, so it is difficult to give a specific number. Here are some factors that can affect the price of customization:

1. Size and specifications: The size and specifications of the customization of the jewelry showcase are an important factor in the customization price. Larger, more complex display cases usually require more materials and manufacturing processes, so the price may be higher.

2. Material selection: The materials customized for jewelry showcase will also have an impact on the price of customization. Different types of glass, metal, wood, or other specialized materials have different costs. High-grade, special materials often add to the price of customization.

3. Design complexity: If the display case requires a complex design, unique shape or special decorative elements, then the custom price may increase accordingly. Manufacturers need to spend more time and effort to meet the special requirements of customers.

4. Production process: If special processing, cutting, engraving or assembly processes are required, then the production process of the jewelry display counter manufacturer may be more complicated, thus increasing the cost.

5. Additional features and decorations: If the display case requires additional features or special decorations, such as lighting systems, security locks, display stands or customized signage, then the customized price may increase.

6. Quantity and volume: If the brand needs to customize multiple display cases, it usually gets a certain volume discount. Therefore, the price of customizing multiple display cases at the jewelry display counter manufacturer may be more economical than the price of customizing a single display case.
