   Testing procedures may differ by supplier in alignment with their internal quality control systems, but each manufacturing partner verifies metal composition at key stages of production using industry-standard analytical methods.

2. 2.

   Once jewelry arrives at Mejuri’s facilities, it is carefully inspected by our Quality Assurance team. As part of this process, each style undergoes X-Ray Fluorescence (XRF) testing, a highly reliable and precise method used to test the metal composition of the piece.

3. 3.

   Where required by law, such as in the UK, our pieces are independently assayed and hallmarked to certify precious metal content.

4. 4.

   Every piece we sell is stamped according to its karatage (e.g., 10k or 14k).

XRF technology works by analyzing how metals respond to X-rays. This allows us to check the metal and confirm its exact percentage makeup. XRF is considered one of the most advanced and dependable testing methods in the fine jewelry industry because it provides accurate, measurable results within seconds without damaging or altering the jewelry. Unlike traditional testing methods that may require filing or chemical solutions, XRF preserves the integrity of the piece while delivering detailed compositional data.

10K gold must contain 41.7% pure gold, and 14K gold must contain 58.5% pure gold.

These minimum gold percentages are mandatory, and we do not accept any items that fall below these requirements. While additional metals such as copper and silver are blended with gold to enhance strength and color (and may vary slightly between batches), the gold content must always meet our specified standards.

When an item is hallmarked 14k or 10k, it is solid gold through and through. Even our hollow-form pieces are crafted entirely from solid gold to meet these strict purity standards. We never substitute solid gold with plating or lower-karat alloys. We clearly label our gold vermeil items separately, as transparency is the cornerstone of our brand.
