In the field of gold and jewelry business, trustworthiness is always prioritized. Customers are becoming more discerning and have higher demands for transparency, especially when it comes to determining the age of gold. Therefore, equipping a modern and accurate gold age testing machine is not only a smart investment but also a core factor in building trust and reputation for a jewelry store. In this article, let’s explore with PMAC why a gold age tester is an essential device and take a closer look at the DXL800 model from the famous Thermo Fisher brand – which we are officially distributing in Vietnam.
1. What is Gold Age? Why is Accurate Testing Important for Jewelry Stores?
1.1 The Concept of Gold Age in the Jewelry Industry
Gold age refers to the purity of gold in a product, typically measured in Karats (K). 24K gold represents 99.99% pure gold. 18K gold contains 75% gold, with the rest being alloyed metals such as silver, copper, etc. Gold with lower Karat values is usually worth less.
However, the market is not always transparent. Many products are gold-plated or alloyed, which can be difficult to distinguish by the naked eye. Specifically, gold items that lack markings or clear origin can cause confusion, directly affecting the store’s profits and reputation.
1.2 Why is Correct Gold Age Testing Important in Transactions?
Accurately determining the age of gold plays a vital role:
- For sellers: It ensures the correct gold quality is sold, avoiding the risk of selling misrepresented gold or losing money by purchasing gold with incorrect age.
- For customers: It builds trust, transparency, and satisfaction in transactions.
- For legal compliance: It ensures adherence to regulations regarding the certification and quality testing of gold and jewelry products.
2. The Risks of Not Using a Gold Age Tester
Many smaller jewelry stores still rely on traditional methods to determine the age of gold, such as checking color, observing engravings, using acids, or scratching the gold on a stone. These methods carry several risks:
- Misidentifying the gold’s age, leading to financial losses.
- Difficulty distinguishing between fake gold, gold-plated items, or unusual alloys.
- Financial losses if incorrect gold age is purchased.
- Reduced trust and credibility from customers due to lack of transparency and clear certification.
As customers become more knowledgeable and have higher expectations, jewelry stores without professional testing solutions will quickly fall behind.
3. What is a Gold Age Tester? How Does it Work?
3.1 What is a Gold Age Tester?
A gold age tester is a device that uses X-ray fluorescence (XRF) technology to accurately determine the metal composition of a product without damaging it. The machine works by emitting X-rays onto the material, then analyzing the fluorescent signals that return from elements like gold, silver, copper, nickel, zinc, etc., to determine the percentage of each element in the alloy.
Operating Principle:
- The device emits X-rays onto the metal sample.
- The elements in the sample react and emit fluorescence, each element emitting a distinct wavelength.
- The machine analyzes the fluorescence spectrum to determine the metal composition and calculate the gold percentage in the alloy.
3.2 Outstanding Advantages of X-ray Fluorescence (XRF) Technology
X-ray fluorescence (XRF) technology allows for quick, non-destructive analysis of a sample with high accuracy, typically within seconds. The device determines the percentage of each element such as gold, silver, copper, and nickel, helping to accurately assess the gold’s age and alloy quality. XRF is not only fast but also versatile in analyzing multi-element compositions, minimizing errors in gold transactions and providing transparent certification reports. The machine’s intuitive touch interface makes it easy for anyone—even those without expertise—to operate, saving time and effort. These advantages make XRF technology the optimal solution in modern metal and jewelry testing.
4. Benefits of Equipping a Gold Age Tester in a Jewelry Store
4.1 Quick Measurement – Non-Destructive – Highly Accurate Results
One of the major advantages is that the XRF machine does not require sample destruction, so it won’t damage or scratch the jewelry. Simply place the sample on the machine, and in just a few seconds, you will get an accurate result down to the percentage.
4.2 Increase Credibility When Transacting Directly with Customers
Measuring the gold in front of the customer, providing clear and transparent results, creates trust, professionalism, and credibility—especially important in large transactions or gold purchases.
4.3 Support Efficient Inventory Management and Gold Classification
For stores involved in manufacturing or purchasing gold in bulk, the gold age tester helps quickly check the gold’s age, avoiding errors in storage, pricing, and classification.
4.4 Minimize Errors, Optimize Long-Term Profit
Purchasing a few grams of gold with the wrong age can result in a significant loss. Meanwhile, investing in a gold age tester is a one-time cost that lasts for many years.
