Company quality-management certificate
The company-published certificate image names Shenzhen Xinyashang Jewelry Co., Ltd. and references GB/T19001-2016 / ISO 9001:2015 for jewelry research, development and related production management activities. It shows issue date 2 February 2024, certificate number 609-24-QW-01192-RO-S and a stated term through 1 February 2027. The document says annual surveillance is required; ask us to confirm its current registry status before relying on it.
Product-specific reports
Product test results are separate from a company management-system certificate. Requirements such as nickel and lead limits, RoHS, REACH or California Proposition 65 depend on the product and destination market. SGS is a testing organization, not a universal product certification. We will discuss which current report or test is relevant to the item you are considering; this page does not claim every product has passed every test.
Nickel-release testing
A test report may be requested for jewelry intended for prolonged skin contact. The sample reference NJ-DEMO-NI-001 shown on the homepage is an illustrative layout identifier; it is not an issued report number or evidence of a passing result.
Restricted-substances testing
Relevant substances and test methods depend on the material and destination market. The homepage sample reference NJ-DEMO-RS-002 illustrates how a report could be organized. It is not an issued report number or a claim of REACH compliance.
Material-composition testing
An alloy composition or precious-metal assay report must identify the specific item and tested sample. The homepage sample reference NJ-DEMO-MC-003 is illustrative only and does not establish a product’s metal content.
Plating-durability testing
Coating and finish performance tests should be selected for the actual plated design and intended use. The homepage sample reference NJ-DEMO-PD-004 is an illustrative layout identifier, not an issued report number or a durability claim.
