Customer Questions & Answers
-
Question:
What is the cultj Diamond SelectorⅡMoissanite Tester Pen?
Answer: The cultj Diamond SelectorⅡMoissanite Tester Pen is a high-precision testing tool designed to distinguish between genuine diamonds and other gemstone simulants like Moissanite. It works by measuring the thermal conductivity of the stone, ensuring accurate results. This tester is essential for jewelers, gemologists, and anyone requiring dependable testing for authenticity, making it a must-have in any jewelry toolkit. -
Question:
How does the Diamond SelectorⅡMoissanite Tester work?
Answer: This pen operates on the principle of thermal conductivity. Diamonds conduct heat differently than Moissanite and other stones, and the tester utilizes this property to provide reliable results. After lightly touching the stone's surface with the pen, you can read the results on the indicator. This feature is useful in scenarios where visual assessment alone may lead to misidentification. -
Question:
Is the Diamond SelectorⅡ suitable for all types of stones?
Answer: While the cultj Diamond SelectorⅡ is primarily designed to differentiate diamonds from Moissanite, it can also be used on some other gemstones. However, it may not be effective for testing certain stones like colored gems or opaque materials. For optimal results, it's best suited for standard gem jewelry and can be crucial in jewelry shops or for individual users wanting to assess their stone's authenticity. -
Question:
What is the advantage of using this professional type tester?
Answer: The professional type of the Diamond SelectorⅡ offers enhanced accuracy and reliability compared to basic testers. Built with advanced software and sensitive sensors, it ensures consistent readings and helps eliminate guesswork. Its compact design makes it portable and handy for professionals or enthusiasts needing reliable testing on the go, making it an integral tool for ensuring the quality of gemstones. -
Question:
Can I use this tester in low-light conditions?
Answer: Yes, the cultj Diamond SelectorⅡ is designed with usability in mind, even in low-light conditions. The indicator is easy to read, ensuring you can conduct your tests virtually anywhere. This feature is particularly beneficial for jewelers attending trade shows or outdoor events who might not have access to ideal lighting, allowing for flexibility without compromising on accuracy. -
Question:
How long does the battery last in this tester?
Answer: The Diamond SelectorⅡMoissanite Tester is equipped with a long-lasting battery, specifically designed to support extended usage without frequent replacements. Depending on the frequency of use, it can sustain hundreds of tests before a replacement is necessary. This longevity is advantageous for busy professionals who require a reliable tool at all times, helping them focus on their work without interruptions. -
Question:
Is there a calibration process for this diamond tester?
Answer: Yes, the Diamond SelectorⅡ requires minimal calibration to ensure peak performance. It typically features a simple calibration button that allows users to adjust for optimal accuracy before testing. Regular calibration is essential, especially for users conducting frequent tests, as it maintains the reliability and precision of the results, providing confidence in every assessment. -
Question:
What are Moissanites and how do they differ from diamonds?
Answer: Moissanites are lab-created gemstones that resemble diamonds in appearance but differ in their physical and optical properties. They have a higher refractive index, making them sparkle more than diamonds, and are significantly less expensive. Understanding these differences is vital for anyone in the jewelry industry, as it helps in correctly identifying and valuing the stones, ensuring customers make informed decisions. -
Question:
Where can I buy cultj Diamond SelectorⅡMoissanite Tester in Turkmenistan?
Answer: You can purchase the cultj Diamond SelectorⅡMoissanite Tester from Ubuy in Turkmenistan. Ubuy offers a convenient platform with a wide selection of products, ensuring you find what you need with great ease. Their extensive inventory and reliable service make it a preferred destination for customers looking to acquire high-quality testing tools like the Diamond Selector. -
Question:
Why is it important to verify diamonds and Moissanite?
Answer: Verifying diamonds and Moissanite is crucial for ensuring the authenticity and value of gemstones. This distinction can significantly affect price, as genuine diamonds typically command a higher market value. For jewelers, being able to accurately test stones protects their reputation and ensures customer trust. It's equally important for buyers to understand what they are purchasing to make informed decisions in their investments.
cultj Diamond Testers Editorial Review
Diamond Combo Tester II Professional Moissanite Low Conductivity Moissanite HPHT Type lab-Grown Diamond Tester is a handheld device that provides diamond measurements using a battery-powered, ohmmeter measurement type. Users have had mixed feelings about its reliability, with some noting it being light and recommendable, while others express significant disappointment regarding its inconsistent readings on stones. The absence of a user manual or charger has also been a common issue among buyers. Although the tester's design is sleek and its weight manageable, the variability in its performance leads some to question its overall effectiveness.
