Vibration Abrasion Test
Helps determine the amount of wear and tear apiece of jewelry can undergo, the time period for thetest varies from 5-20 minutes depending on thecoating thickness.
Sulfur Dioxide Test
The test involves two stages where the first one isputting the jewelry in 10% sulfuric acid water for 24hrsand the second is to rinsed the products thoroughlywith deionized water.
Artificial Sweat Test
In the 40'c and PH5.5 environment, artificial sweat isspray onto the products constantly for 48 hrs to see ifthe jewelry is sweatproof and anti-tarnish.
UV Test

Rubbing Test
Grinded(or rubbed) 50 times back and forth by abelt, only those jewelry will a still complete coatingcan pass the test. This test ensures the platingcoating is strong enough.

- Mechanical Integrity: All mechanical components (clasps, locks, etc.) are crafted to match the confirmed CAD design exactly.
- Structural Durability: We rigorously test structural strength to eliminate risks of cracking, misshaping, or gemstone dislodgement.
- Material Fidelity: Gemstones and metal parts adhere strictly to the design file, matching cut, shape, quantity, finishes, and overall appearance. Colors align with standard color charts for consistency.
Appearance Inspection
- Welding Precision: All welding points are seamlessly executed, leaving no visible marks or imperfections.
