In the jewelry industry, “gold purity” is not just a technical number – it is a decisive factor in product value, customer trust, and brand reputation. However, accurately determining gold purity has never been easy, especially in the context of a market with an increasing number of adulterated, plated, or sophisticated counterfeit products.
Faced with this reality, PMAC – a leading provider of advanced analytical equipment – is implementing a free gold purity testing program using modern XRF machines, lasting throughout May 2025. This is not only an opportunity for gold shop owners, manufacturing facilities, and jewelry businesses to accurately verify the quality of their products but also a chance to access the most advanced non-destructive measurement technology available today.
1. The Role of Accurate Gold Purity Determination in the Jewelry Business
For a gold product, “gold purity” indicates the content of pure gold in the alloy – usually expressed as a percentage or in karats (K). For example, 24K gold is 99.99% pure gold, while 18K gold contains about 75% gold.
Accurate gold purity determination is mandatory for:
- Businesses and jewelry stores wishing to transparently list their products.
- Processing and manufacturing facilities needing to inspect incoming materials.
- Consumers wanting to ensure the assets they purchase are genuine and of the correct value.
- Export units needing to meet international inspection standards.
Meanwhile, incorrectly measuring gold purity can lead to a loss of customer trust, affect profits, and even cause legal trouble if the product is determined to not meet the declared quality.
2. XRF Technology – A Modern Gold Purity Testing Solution
2.1 Operating Principle
XRF (X-ray fluorescence) is a material elemental analysis technology based on the phenomenon of X-ray fluorescence emission. When a high-energy X-ray beam is directed at a sample, the atoms inside the material emit characteristic X-rays, allowing the analytical device to accurately determine the chemical composition and the ratio of the elements present.
This is a non-destructive method, requires no sample preparation, analyzes quickly in just a few seconds, and provides highly reliable results.
2.2 Superior Advantages over Manual Methods
- No need for scraping, grinding, or chemical contact like the acid method.
- Preserves the original condition of the product – no scratches or damage.
- High accuracy down to the smallest percentage.
- Detects gold plating or metal coatings.
- Suitable for all types of jewelry: rings, bracelets, necklaces, pressed gold bars, gold jewelry, precious alloys.
