Anodized vs. PVD-Coated Titanium: How to Read the Finish Label
Understand how color anodizing and PVD differ. Separate a jewelry listing’s base metal, finish process, surface material, and color before comparing options.
Anodizing and PVD describe different ways of creating a surface finish. Color anodizing builds an oxide layer on titanium; PVD deposits material onto a surface. Neither the word “gold” nor a gold-colored photo tells you which process was used. To understand a listing, separate the base metal, the process, the surface material, and the color.
Cover note: This SENLANSP catalog image shows a gold-colored appearance. It is not a verified example of either process; a photograph cannot identify how the finish was made.
What happens when titanium is color-anodized?
Color anodizing is an electrochemical treatment that develops a thin oxide layer on the titanium surface. Light interacting with that layer produces interference colors; changing the layer’s thickness changes the visible color. Micron’s description of decorative titanium anodizing explains that the colors are produced without added pigments.
That is why a golden appearance can come from anodized titanium without a gold layer supplying the color. The surface oxide and the way it interacts with light create the effect. KKS’s color-anodizing explanation describes the same oxide buildup and interference mechanism.
Be careful with the shorthand “anodized, not coated.” Anodizing does create a surface layer, and technical sources may call that layer a coating. The useful distinction is how the layer forms.
What does PVD tell you?
PVD stands for physical vapor deposition. In this process, material is vaporized in a vacuum and deposited as a thin film on a component. See Oerlikon’s PVD process description.
The name identifies a deposition process. It does not, by itself, name the deposited material. In a phrase such as “PVD-coated titanium,” titanium describes the stated base metal. You still need the coating description to know what was deposited on it. Adding the color word “gold” does not automatically fill that gap.
Read the finish description in four parts
Look for these details in the specifications for the exact option you selected. A color selector may answer only the last row.
| Detail | What it tells you | What to look for |
|---|---|---|
| Base metal | The metal beneath the finish | A material name, such as titanium, stated separately from the color |
| Process | How the finish was produced | A named process, such as color anodizing or PVD |
| Surface material | What makes up the surface layer | The oxide layer in color-anodized titanium, or the specified deposited material in a PVD finish |
| Color | The appearance of the selected option | A color name such as gold, blue, or purple; this alone does not identify the process or composition |
Try the same check on three short labels
These examples are hypothetical wording, not specifications for SENLANSP products.
- “Titanium — Gold.” You have a stated base metal and a color label. The process and surface material are still missing.
- “Titanium — gold-colored anodized finish.” The wording names the base metal and process. The color comes from the anodized oxide layer; “gold-colored” does not describe a solid-gold piece.
- “PVD-coated titanium — Gold.” The wording identifies the base metal, process, and color. It still leaves the deposited material unspecified.
If a karat number appears, check which layer or component it describes. A statement about a surface layer is different from a statement about the whole piece. Keep the seller’s exact wording instead of shortening everything to “gold titanium.”
Ask for the missing field
When details are absent or inconsistent, send the product link and selected color with a specific question:
For this exact option, what is the base metal, and how is the colored finish produced? If material is deposited, what is that material? Does “gold” describe the color or a gold-containing layer?
If one part of the page names PVD and another names a different process, include both statements in your message and ask the seller to resolve the discrepancy. Choosing whichever description sounds more appealing does not establish how the item was made.
For a SENLANSP listing, contact us with the product link and selected option. Save the confirmed answer and its date with your order details; our body jewelry inventory card provides a place to keep those references.
You can then compare two listings field by field. A matching color may be the look you want, while the process and surface-material descriptions tell you how each seller describes the finish.
