In the case of selling crystal, whether it is necessary to register a trademark depends on your specific needs and business strategy.

trademark registration is a way to protect a trademark as a brand identity. If you want to establish a unique and recognizable brand in the market and protect your trademark from infringement by others, then trademark registration may be beneficial.

through trademark registration, you can obtain the exclusive right to a trademark in a specific region and prevent others from using similar or identical trademarks on similar goods or services. This can help you build brand awareness, maintain consumers' trust in your products, and prevent others from using similar trademarks to engage in similar business and cause confusion.

please note that the procedures and requirements for trademark registration will vary according to different countries and regions. If you want to sell crystals in a specific country or region and protect your trademark rights, it is recommended that you consult the local trademark office or professional trademark agency to understand the relevant trademark registration requirements and procedures.

In short, trademark registration is not mandatory, but it can provide additional legal protection and commercial advantages for your business activities. Therefore, according to your specific situation and business strategy, you can consider trademark registration as an important protection measure.
