Ultra-Shine Finish

This service takes your raw, abrasive-free castings to a clean, bright shine by removing the top dull layer through a controlled abrasive process.

We use a German-made magnetic pin finisher with micro-pins and our proprietary brightening detergent in a 30-minute cycle. On an average-sized 18k gold ring, this process typically removes approximately 0.15-0.20g of gold throughout the entirety of the casted piece.

Note: This is not a full polish. Printing lines and surface texture will remain visible.

Age-Hardening Treatment (Gold Only)

For clients seeking enhanced hardness and tensile strength in their gold castings (not recommended for Silver), we offer mild age-hardening treatments (3-4hr process). This process improves the durability of your pieces while maintaining a careful balance, avoiding the excessive brittleness associated with stronger hardening treatments, this process does change the grain structure of the metal. Our approach ensures a mild increase in tensile strength without compromising overall structural integrity, the result, a casting that is much harder to bend and scratch.

The treatment is performed in a fully temperature-controlled environment, where your castings are heated to precise temperatures, held for the optimal duration, and cooled in accordance to the metal type. This process ensures even and consistent results across every piece. Age-hardening is NOT recommended if you are going to be soldering after casting as this would ruin the grain structure (making it soft again). This service is only recommended where soldering and re-sizing is not required.
