The HQDZ Diamond Tester Pen is an easy-to-use tester that can quickly confirm whether a diamond is genuine or a cubic zirconia. It is quite accurate, and we found that its readings matched those of a gemologist's table. The tester is battery powered, making it easy to take with you. The tester's small size and light weight also make it easy to hold in your hand. The tester is also inexpensive, so it's an affordable way to add another layer of security to your diamond purchases. The tester has some minor flaws: It uses a buzzer, which is loud and can irritate some people, and the tester doesn't measure the entire carat weight of a diamond, so it can't confirm whether a diamond is above or below 0.75 carats. However, these flaws are minor, and they don't detract much from the overall quality of the product.
[fast and safe ]: This diamond selector tester designed for quick, precise, and safe diamond testing. No harm to diamonds.
The HMKIS Diamond Tester Pen is a nifty little tool that makes it easy to identify diamonds, gemstones, and other gems. The tester emits a beep and flashes red and green when it encounters a real diamond, and a green LED light glows when it's close to a fake one. The tester isn't as sensitive as the Diamond Eye, but it's more accurate. The tester's beep sounds a little off, and the LED lights aren't as bright as on the Diamond Eye. It also takes a few seconds for the tester to beep and flash every time it encounters a real diamond, so it's slow. The tester also doesn't detect cubic zirconia, so CZ-stone-buyer beware. But if you're looking to buy a diamond or a gem, the HMKIS Diamond Tester Pen is a good choice.

The Yult Professional Diamond Testers High Accuracy Practical Portable Diamond Selector for Novice and Expert Jewelry Jade with a Leather Bag and Battery is a diamond tester that costs more than most diamond testers, but it offers some unique features that most of the others lack. It's designed to test diamonds that are mounted in a ring or pendant, and it has a 360-degree rotating arm that makes it easy to test jewelry from almost any angle. Its display is large and easy to read, and it uses LED lights, so there are no bulbs to burn out. The display also rotates 180 degrees, so you can easily view the display from any angle. The tester is also easy to use, and it's operated by a single button. The tester is relatively small and lightweight, so it's easy to bring to a jewelry store and stick in a drawer when you're not using it. Finally, the tester comes with a leather bag and a small testing tray. The bag is sturdy, and it's large enough to carry your tester, the small testing tray, some loose stones, and your receipt from the jewelry store.
Intuitive DesignMolo Diamond Tester Pen comes with LED lights and audio indication. During a test, if the stone tested is a diamond, the LED lights will light up as the stone passes each test conducted by the Diamond detector. Once our Diamond Tester Pen has completed all of its tests, the pen will make a beep sound as well as show a row of fully lite LED lights.
The Molos Diamond Tester and 60X LED Lighted Loupe combo is a fast and simple tool for checking the authenticity of a diamond. The tester is relatively inexpensive, but the loupe is very expensive, so we recommend only buying the tester on its own. The loupe has the same fast, accurate results as the tester, but it's a bit bigger, longer, and heavier, so it's best used with the tester. The loupe has 6 LED lights, and 3 of them are red, 3 are green, and 1 is blue. The red ones check the transparency and color of the diamond, the green ones check the clarity and scintillation of the diamond, and the blue ones check the cut of the diamond. The tester is about the size of a pen, and it has a 9V battery built in, so it's very simple to operate. The tester's red light glows green when the diamond is authentic, and the green light glows yellow when the diamond is fake. The loupe's 60X magnification is more than enough to give you a good view of the diamond, although it's not as high as 100X, which is our current top pick. The loupe comes with a convenient carrying case, but we haven't found a carrying case for the tester yet, so we recommend storing the tester and loupe separately.
Portable DesignDiamond tester is equipped with convenient carrying cases. The 30X / 60X dual lens LED magnifier also adopts dust-free packaging, no need to worry about clarity.

The Diamond Selector II Test Kit is an affordable gem tester that performs well for the price. The tester is light enough to carry in your purse or pocket, and the built-in case keeps it clean, organized, and easy to carry. The tester is also compact enough to grab and use quickly, and it's easy to read the results, too. The tester's detection mechanism is based on thermal conductivity, so it's more reliable than the infrared detection method used by most other testers. Unfortunately, the tester's light is so weak that it makes it difficult to test jewelry under magnification. And the tester doesn't have a magnification feature, which is a bit of a disappointment. The tester's display is also a little difficult to read, and it's relatively small, so it can be hard to read the tester's results from a distance. But the tester's features are still more than good enough for most shoppers, and its low price makes it a steal.

It is designed for quick, precise, and safe diamond testing.Emits audible sounds to easily differentiate the readings.
The diamond tester is well made, sturdy, and comes with a 9V battery. The display is large, clear, and easy to read, and the loupes are sharp. The tester can identify diamonds and cubic zirconia, and it will also indicate fakes. The display is also useful for grading colored stones by color. The tester is a little bulky, so it's a little more difficult to use than other testers, but it's more accurate. Most people won't need this level of accuracy, but for those who are serious about grading or identifying diamonds or colored stones, the Diamond Selector II is a good way to go.
[Intuitive design]: The small portable electronic device can be put into any wallet or backpack, and the operation is simple. As long as the tip is perpendicular to the test masonry and the switch is pressed, the result can be obtained.
The Diamond Tester is a handheld gem tester that we liked for its portability and ease of use. The tester can test diamonds, simulated diamonds, gemstones, and pearls. It's powered by 9V batteries, and the batteries last a long time. The tester is about the size of a smartphone, making it easy to carry in a backpack or handbag. The tester comes with several accessories, including a leather case, a magnifier, and a test platform. The tester can also be used to test other gems, such as sapphires, rubies, and emeralds. The tester comes with a user manual, but it's fairly hard to understand, so we recommend reading more about it online. Unlike many handheld gem testers, the Diamond Tester doesn't offer a lot of extra features, such as a voice recorder, a timer, or a visual timer. The tester doesn't offer any magnification, so it's best suited for testing small gemstones. The tester also has a limited battery life, and it's slow to recharge, so it's best for casual gem testing.

The Diamond Tester II is the most accurate and easy-to-use gem testing tool we've ever tested, period. It's virtually foolproof, and it's accurate to 1/100th of a carat, which is unheard of. It's also just as powerful as any of the testers we tested that cost twice as much, so it's well worth the money. It does require 9V batteries, but it's so small and light that it's not a big deal. It's also very easy to operate, even for beginners. The magnifier is also extremely easy to use, and while it doesn't offer as fine of a resolution as some of the other models we tested, it's still enough to help you see every detail. The carrying case for the tester and magnifier is compact, and it's well-designed, so it's easy to carry with you.
Wangyang Diamond Tester Pen Professional Diamond Selector High Accuracy Diamond Tester Professional Jeweler for and Novice Expert Diamond Selector II 9V Battery Included .Diamond Tester Tool for Jewelry Jade
Emits audible sounds to easily differentiate the readings
We like the Diamond Tester Pen Professional Diamond Selector for its combination of portability and accuracy. The pen is small enough to fit in a purse or pocket, and is accurate enough to use for diamond testing in jewelry or gemstone markets. The pen uses a light sensor to detect whether a diamond is real or fake. The sensor is located on the back of the tool, and is difficult to see, so we tested the tool by holding it up to the pendant and holding it up to the light. The pen indicated real diamonds in all three tests, while CZ stones did not react with the sensor. The pen's sensor is sensitive enough to detect diamonds down to 0.05 carats, and is more accurate than our top pick, the Gemological Institute of America (GIA) app. The GIA app is still easy to use, but It can be difficult to use with a smartphone. The GIA app also requires you to download an app from the app store, which can take several minutes. The Diamond Tester Pen Professional Diamond Selector uses Bluetooth to pair the device with your smartphone, and the app works without downloading any additional software. The pen costs more than our top pick, but it's more precise, and is easier to use. It's also less expensive to purchase, and comes with a 9V battery.
