This workflow is for trade-in and refurbished jewellery that needs an even, stable refreshed lustre after light wear without turning the task into complete repolishing. Before work begins, agree the commercial endpoint and record the initial condition of the surface, edges, relief, joints, settings, stones, and inserts.

When this workflow is eligible

Use this workflow only when all of the following are true:

  • the working surface is open bare metal without a coating;
  • the material is a copper alloy including brass or bronze, a silver alloy, or most gold alloys;
  • the surface has only minor wear marks or micro-scratches;
  • geometry, edges, and relief remain intact;
  • the item does not require repair or abrasive preparation;
  • construction, soldered joints, settings, stones, and inserts permit the selected operations;
  • the agreed endpoint is a commercial refresh, not complete restoration or a new-jewellery finish.

If deep scratches, dents, waviness, geometry loss, cracks, pores, open cavities, raised repair defects, or other damage are present, remove the item from this workflow. Continue with Surface preparation before LUXI and then the basic LUXI production route for first-group materials.

Exclude coating risk first

The direct branch of this workflow applies only to open bare metal without a coating.

If a coating is unknown, damaged, or uncertain, do not begin a trial polish with LUXI Blue. Start with the second-hand coated item risk assessment. For an item with an already damaged coating, use the coated-item restoration decision.

Do not mechanically polish a thin decorative, protective, electroplated, PVD, or other layer that must be preserved. A sufficiently thick, continuous, stable, and well-adhered metallic coating may be considered only in a separate material-specific branch after the layer system has been identified and a test has been completed on a matching sample or non-critical area. Such a coating is not an automatic entry into this workflow.

Working combination and operating range

Use LUXI Blue on a separate clean white stitched muslin wheel. This is the sole working combination in this limited workflow. If the wheel shape cannot preserve the item geometry and relief safely, select another appropriate workflow.

For a standard wheel approximately 150 mm in diameter, use 2500–3000 rpm as the working starting range. Do not transfer this range automatically to another wheel diameter. Select conditions for another diameter according to actual linear surface speed, contact area, wheel stability, and surface temperature.

Before work, confirm that the wheel is dry, clean, and not overloaded with old compound or removed metal. When necessary, clean the wheel fully and restore an even working face. The complete procedure is provided in Wheel preparation and minimal LUXI compound application.

Performing the light refresh

  1. Inspect the item under directed light and confirm that the damage is limited to minor wear.
  2. When the risk is acceptable, begin with a short test on a non-critical area of open metal.
  3. Apply LUXI Blue minimally. No visible blue layer should remain on the stopped wheel.
  4. Work in short passes and keep the item moving relative to the wheel.
  5. Use only enough pressure for stable contact without overheating, edge loss, relief smoothing, or geometry distortion.
  6. Stop regularly and check temperature, wheel condition, and result uniformity.
  7. After a controlled series of passes, wash the item completely, dry it, allow it to cool, and inspect it under directed light.

Completion criterion

The one-step refresh is complete only after full washing, drying, and cooling, when directed-light inspection confirms all of the following:

  • minor wear has been reduced to the agreed commercial endpoint;
  • the surface has an even, stable lustre;
  • geometry, edges, and relief remain intact;
  • there is no colour change, coating change, or breakthrough to an underlayer;
  • no new pores, cracks, cavities, or other defects have opened;
  • the result remains stable after washing.

When these conditions are met, this limited one-step workflow ends. No finishing compound is part of this workflow.

When to stop and change workflow

If LUXI Blue cannot safely reach the agreed result, do not increase the amount of LUXI Blue, pressure, or continuous contact time, and do not append a finishing compound to this workflow.

Stop and reclassify the task when:

  • deep scratches or pronounced wear remain;
  • geometry correction or repair is required;
  • edges or relief begin to soften;
  • the surface overheats;
  • colour changes or a previously unidentified coating appears;
  • pores, cracks, cavities, or other defects open;
  • lustre becomes uneven or unstable after washing.

Return to surface preparation and a complete staged polishing route when required. For newly opened defects, use the LUXI diagnostic test polish. For a large planar surface where LUXI Blue is not active enough, use the first-stage escalation workflow.

Washing and final assessment

A compatible washing solution may be used. LUXI iClean is recommended as the most compatible option because it is formulated with the chemistry of LUXI compounds in mind, allows the item to be washed under gentler conditions, and helps keep the polished surface stable. Other compatible washing solutions may also be used.

Ultrasonic washing, heated solution, and steam cleaning require whole-item eligibility, including the material, construction, stones, inserts, adhesive joints, soldered joints, hollow elements, and any coating.

The full procedure is provided in Washing after LUXI polishing. Make the final decision only on a fully washed, dry, and cool surface under directed light.
