Jewelry testing requires precise observation of details. This stage is made of aluminum alloy, which has excellent texture and will not cause damage to jewelry. Driven by a micrometer, the stage enables precise adjustment; its 360° rotation function allows for an all-round display of the jewelry's appearance, while the ±5° fine adjustment can focus on details such as the jewelry's texture and flaws. It helps appraisers accurately judge the quality and authenticity of jewelry, providing technical support for fair transactions in the jewelry industry.
