You see beautiful gold, pink, or blue earrings in our store and wonder, “Won’t the paint chip off while I’m wearing them?”
We have great news for you: It’s not paint. It’s pure physics and chemistry. Learn about the anodizing process—the only way to create colored jewelry that’s 100% safe, even for fresh piercings.
What Is Anodizing? (Definition)
Anodizing is an electrochemical process that changes the properties of a metal’s surface (in our case, G23 titanium or niobium).
Simply put: We submerge a titanium earring in water containing an electrolyte and pass an electric current through it. Under the influence of the voltage, a very thin, transparent layer of titanium oxide forms on the surface of the titanium.
Where does the color come from?
This is the most interesting part! The oxide layer acts like a prism. Depending on the thickness of this layer (which we control using the voltage), light reflects off it differently, and our eye perceives a specific color.
Low voltage = Gold / Brown
Medium voltage = Blue / Purple
High voltage = Pink / Green / Turquoise
Conclusion: Anodized titanium is still the same, safe titanium, just “clad” in light. There are no dyes, paints, or toxic chemicals involved.
Anodizing vs. Painting (Why Does It Matter?)
For your health, the difference is enormous.
| Feature | Anodizing (Titanium) | Regular Painting/Varnish |
| Safety | ✅ 100% safe, hypoallergenic | ❌ Risk of allergies and toxins |
| Durability | ✅ Does not chip (is part of the metal) | ❌ Chips off, creating sharp edges |
| Healing | ✅ Can be used on a fresh piercing | ❌ Only for healed piercings (or not at all) |
| Surface | ✅ Perfectly smooth | ❌ Often rough (bacteria) |
Is anodized titanium safe?
Yes, it is one of the safest forms of jewelry in the world.
The anodizing process not only adds color but also passivates the metal’s surface. This means the earring becomes even smoother and more corrosion-resistant, making it an ideal choice for people with allergies and those with sensitive skin.
Does the anodized finish wear off?
Anodizing won’t “chip” like paint, but it may fade over time.
Since the color depends on the thickness of the oxide layer, daily wear and contact with sweat, cosmetics, or sebum can gradually wear away this layer over time, restoring the earring to its natural, silvery titanium color. This is a natural and harmless process.
Fun fact: Anodized jewelry can often be re-anodized (to refresh the color)!
What CAN’T be achieved through anodizing?
Not all colors can be achieved through this process.
🔴 Red: Titanium does not anodize to a blood-red color (it tends to turn pink instead).
⚫ Black: True black cannot be achieved through anodizing. Black earrings are usually made of titanium coated with PVD (also safe, but different from anodizing).
Summary: Why choose anodized G23 titanium?
Safety: No nickel or toxic dyes.
Uniqueness: You can have an earring in Blurple, Gold, or Pink while retaining the properties of medical-grade titanium.
Hygiene: The smooth surface promotes healing.
