Browse →Which material is safest for my piercing?
The safest material depends on your piercing type, healing stage, and metal sensitivity. ASTM F136 implant-grade titanium is the universal gold standard — nickel-free, biocompatible, and suitable for initial piercings and sensitive skin. ASTM F138 surgical steel offers budget-friendly quality for healed piercings. 925 sterling silver is nickel-free but best for healed ear piercings only. 14K solid gold combines luxury with full biocompatibility.

Why choose Piercova?
Are Piercova products ASTM certified?
Yes. All materials are verified to ASTM International standards — F136 for titanium, F138 for surgical steel, B700 for sterling silver. Each standard is independently verifiable and publicly documented.
What does "implant-grade" actually mean?
Implant-grade means the material meets the same ASTM specifications required for surgical implants — hip replacements, bone screws, dental implants. It is not a marketing term; it is a legally defined standard for composition, mechanical properties, and biocompatibility.
Which materials are nickel-free?
Titanium (ASTM F136), sterling silver (925), and solid gold (14K yellow/rose) contain zero nickel. Only ASTM F138 surgical steel contains 12-14% nickel — bound within the alloy structure and generally safe unless you have a confirmed nickel allergy.
