Sun Yin Crystal Passes California Proposition 65 Compliance Testing
We are proud to announce that Sun Yin Crystal Industry Co., Ltd. has officially achieved compliance certification for California Proposition 65 (CP65).
California Proposition 65 (Safe Drinking Water and Toxic Enforcement Act) is one of the world’s most stringent environmental safety standards, regulating substances known to cause cancer, birth defects, or other reproductive harm.
Through rigorous independent third-party laboratory testing, our synthetic sapphire glass and precision technical ceramic products have been verified to be completely free of regulated harmful heavy metals (such as Lead, Cadmium, and Phthalates).
What This Means for Our Clients

- Eco-Friendly & Safe: Ideal for intimate skin-contact products, including high-end watch cases, smart ring shells, and medical/beauty equipment components.
