While standard gold vermeil typically features a 2.5-micron layer, we choose to go further to ensure the longevity of our collections. Our pieces are generously finished with a minimum of 3 microns of 18k gold—exceeding industry expectations for a silhouette that is as resilient as it is radiant. We believe 18k gold offers the definitive balance of rich, deep colour and enduring value.
For our silver designs, we apply a premium rhodium plating—a rare member of the platinum family. This finish is meticulously chosen to enhance the jewellery’s brilliance and tarnish resistance, ensuring each piece retains its high-lustre glow through daily wear.
The enduring quality of our jewellery and the safety of our clients are our primary concerns. Every Ugems co. design is developed according to a meticulous quality control programme to ensure our collections are hypoallergenic and structurally flawless.
To provide the ultimate assurance of reliability, our production is subject to a scheduled testing plan conducted by ISO 17025 accredited laboratories. This rigorous oversight confirms our technical competence and adherence to global safety standards, including:
Hypoallergenic & Nickel Safety: Regular batch testing for nickel release (EN1811 & EN12472 standards) to ensure every coated item is safe for sensitive skin.
Material Purity: Strict compliance checks against established safety limits for lead and cadmium content in all metals and components (ASTM F2999-19).
Structural Resilience: Physical and mechanical stress tests at the development stage to guarantee the architectural durability of each design.
Global Safety Compliance: Flammability and consumer product safety evaluations in accordance with regulations set by the U.S. Consumer Product Safety Commission (CPSC) and ASTM International (formerly the American Society for Testing and Materials).
