Customer Questions & Answers
-
Question:
What is the Presidium Diamond Mate A (PDMT-A) Diamond Tester used for?
Answer: The Presidium Diamond Mate A (PDMT-A) is used to determine the authenticity of diamonds and diamond simulants through thermal conductivity. This professional handheld device allows users to quickly test gemstones, ensuring confidence in purchases and evaluations. It is particularly useful in jewelry stores, by gemologists, or for enthusiasts who want to verify their jewelry's value. -
Question:
How does the thermal conductivity testing feature work?
Answer: The tester measures how well a stone conducts heat, which differs between diamonds and simulants. Diamonds have a unique thermal conductivity level that enables the tester to identify them accurately. When testing, simply place the stone in contact with the probe, and the device will indicate through a color-coded scale whether it's a diamond or not, giving you reliable results with each test. -
Question:
Is the Presidium Diamond Mate A easy to use for beginners?
Answer: Yes, the Presidium Diamond Mate A is designed with user-friendliness in mind. With a simple interface, even beginners can perform tests efficiently. Just switch it on, wait for the readiness indicator, and place the stone against the probe. This makes it suitable not only for professionals but also for hobbyists who want to learn more about gemstone identification. -
Question:
What precautions should I take when using the diamond tester?
Answer: To ensure accurate readings, always test in a clean environment, free from dust or contamination. Avoid using on stones that are chemically treated as this may affect results. It's also important to let the probe cool down after several uses to maintain consistent performance. Following these precautions will enhance the accuracy of your testing results. -
Question:
Does the tester provide alerts for low battery?
Answer: Yes, the Presidium Diamond Mate A includes a low battery indicator feature. This notifies users when the battery life is running low, ensuring that you are always aware of when the device may need new batteries. This feature is essential for ongoing use, preventing unexpected shutdowns during critical testing times. -
Question:
Can the Presidium Diamond Mate A test other gemstones?
Answer: While the primary focus is on diamonds and diamond simulants, the Presidium Diamond Mate A can also provide readings on other gemstones that exhibit similar thermal conductivity properties. However, results could vary for stones outside its intended use, so it's best utilized specifically for diamonds to ensure reliable verification. -
Question:
What is the significance of the metal alert feature?
Answer: The metal alert feature of the Presidium Diamond Mate A indicates the presence of metal in contact with the probe. This is critical for ensuring accurate gemstone testing because metallic settings can interfere with readings. By alerting users to potential contamination from metal, the tester enhances accuracy, making it ideal for jewelers who need precision. -
Question:
How portable is the Presidium Diamond Mate A Diamond Tester?
Answer: The design of the Presidium Diamond Mate A is compact and lightweight, making it highly portable. Its handheld format allows for easy transportation to jewelry shows, gemological conferences, or while traveling. This flexibility enables gemologists and jewelry professionals to conduct tests on-site without hassle. -
Question:
Is the Presidium Diamond Mate A suitable for professional use?
Answer: Absolutely, the Presidium Diamond Mate A is tailored for professional use with its advanced testing features and durability. Experts in jewelry retailing, appraisers, and gemologists prefer this model due to its reliability and precision. Whether for inventory assessment or client consultations, this tester enhances professional credibility and trust. -
