About Piercova

What is Piercova's mission?

Piercova exists to make implant-grade body jewelry accessible — ensuring every customer receives jewelry that is safe, biocompatible, and manufactured to verifiable ASTM standards, regardless of budget. No mystery metals, no vague terminology without traceability.

What does "implant-grade" actually mean?

"Implant-grade" is a legal and technical standard defined by ASTM International, not a marketing term. Our ASTM F136 titanium is chemically identical to the alloy used in hip replacements and dental implants. ASTM F138 surgical steel undergoes vacuum-melting to eliminate impurities — the same process used for bone screws and orthopedic fixation devices. Material composition, mechanical properties, and biocompatibility are independently verifiable against published standards.

Which ASTM standards does Piercova follow?

• ASTM F136 — Implant-grade titanium alloy (Ti-6Al-4V ELI). Nickel-free. Used in surgical implants.
• ASTM F138 — Implant-grade 316LVM stainless steel. Vacuum-melted for purity. Used in orthopedic devices.
• 925 Sterling Silver — 92.5% pure silver. ASTM B700 standard. Nickel-free alloy.
• 14K Solid Gold — 58.5% pure gold. Solid throughout, not plated or filled. Nickel-free options available.
