Why Your Jewelry Still Has Scratches (And How to Fix It)

You've spent hours fabricating a beautiful ring. The soldering is clean, the stone is set perfectly, and you take it to the polishing wheel expecting a mirror finish. But when you hold it up to the light... scratches. Everywhere.

Sound familiar? You're not alone. It's the most common frustration we hear from jewelers, and it comes down to one thing: the steps between fabrication and polish are either missing or incomplete.

The Problem: Polishing Compound Doesn't Fix Surfaces

Here's what most jewelers don't realize early on: polishing compound (rouge, ZAM, Fabulustre, whatever you prefer) doesn't remove scratches. It makes surfaces shiny. If the surface has scratches going into the polishing step, it'll have shiny scratches coming out.

The job of polishing compound is to bring an already-smooth surface to a mirror finish. The job of getting the surface smooth belongs to abrasives — and not sandpaper.

Why Sandpaper Falls Short

Sandpaper works fine on flat surfaces. But jewelry isn't flat. Rings curve, bezels have corners, prongs are tiny, and solder joints sit at junctions between multiple surfaces. Sandpaper:

• Loads up quickly on precious metals (especially silver)
• Curls and folds in tight spaces
• Leaves inconsistent scratch patterns on curved surfaces
• Can't reach inside ring bands, between prongs, or along channels

The Fix: A Systematic Grit Progression

Professional jewelers use rubber-bonded abrasives (like Cratex) between fabrication and polish. Here's why it works:

1. Start at the right grit for your surface condition. Post-soldering cleanup? Medium. Heavy casting marks? Coarse. Light tool marks? Fine.
2. Work through every grit in order. Each grit removes the scratch pattern of the previous one. Coarse → Medium → Fine → Extra Fine. No skipping.
3. Use shapes that match your geometry. Wheels for broad surfaces. Points for tight spots. Cones for inside curves. The rubber bond conforms to your piece instead of fighting it.
4. Only then go to polish. When you reach polishing compound, the surface should already be smooth to the naked eye. Polish just adds the shine.

The Color-Coded System

Cratex makes this easy with color-coded grits: green (Coarse), brown (Medium), red (Fine), white (Extra Fine). No guessing which grit you grabbed. Work through the colors in order, and your surface is ready for polish.

For precious metals that need a true mirror, MX wheels add an even finer step between Extra Fine and polishing compound — the step that makes the difference between "good" and "flawless."

Try It Yourself

If you've been going straight from fabrication to polish and wondering why your work has scratches, add the middle steps. Our Jeweler's Starter Finishing Kit ($125) gives you wheels, points, and mandrels across all four grits — everything you need to see the difference immediately.

Or read our Complete Jeweler's Guide to Cratex Finishing for the full breakdown of grits, shapes, techniques, and metal-specific tips.

Your jewelry deserves a finish that matches the craftsmanship you put into it. Stop fighting scratches and start finishing properly.
