Many stones can pass a diamond tester because they contain the same chemical and physical properties as diamond. Stones that can pass a diamond tester include cubic zirconia, moissanite, white sapphires, white topaz, and several other colored gemstones like rubies, emeralds, and sapphires.
However, it is important to note that the only stones that will pass a diamond tester are those that are pure and have not been treated with any chemical or physical enhancements. Cubic zirconia, white sapphires, and moissanite are stones that can often pass a diamond tester since they have a very similar makeup to a diamond.
On the other hand, many colored gemstones can occasionally pass a diamond tester, but this is a much rarer occurrence. Ultimately, the only stone that will always pass a diamond tester is a genuine diamond.

Can a diamond tester test other stones?
No, a diamond tester is specifically designed to test diamonds. It works by measuring the electrical resistance of the stone, which will be different for a diamond than almost any other gemstone. Diamond testers can be used to detect synthetic diamonds and differentiate them from natural diamonds, but they cannot determine the value of a diamond or identify any type of gemstones other than diamonds.
Do diamond testers only work on diamonds?
No, diamond testers do not only work on diamonds. In addition to diamonds, diamond testers can also be used to identify certain other gemstones, such as colored gems, moissanite and diamond simulants like cubic zirconia.
Diamond testers use a principle known as thermal conductivity, which measures the heat transfer from the gemstone to the probe. The rate at which the gemstone cools is what’s being evaluated and depending on the type of stone, the machine will be able to identify it easily.
In addition, there are some types of diamond testers, such as electrical current testers, which enable accurate identification of gemstones through the determination of a gemstone’s electrical current, further proving their versatility.
How do you use diamond tester on gemstones?
Using a diamond tester on a gemstone is a simple process. Depending on the type of diamond tester you have, you will need to turn it on, wait for the indicator light to come on, and then select the gemstone setting.
Place the gemstone in the slot on the tester and press the test head onto the stone to make contact. Depending on the type of diamond tester you are using, it will give an indication if the stone you are testing is a diamond or not, either through a change in tone, a light, an LED display or other technology.
Additionally, some testers will also identify whether the stone is a natural diamond or a synthetic diamond. If a stone is not a diamond, the tester will indicate the result, typically with some type of audio sound.
You can then repeat the same process for other gemstones you may be interested in testing.
How can you tell if a diamond is real tester?
The most reliable way to determine if a diamond is real is to have it examined by a qualified gemologist. Gemologists have access to special tools and equipment such as a 10x loupe, polariscopes, densimeters, and microscopes to evaluate the stone’s physical and chemical characteristics and determine its authenticity.
A visual examination is the first step in testing a diamond’s authenticity. Look closely at the stone and check for flaws, characteristics, and inclusions that are not normally seen in fakes. The facets should be sharp and symmetrical.
If the facets seem off, the diamond is likely not real.
A loupe allows gemologists to spot imperfections that are not visible to the naked eye. The loupe also helps identify a real diamond from glass or cubic zirconia by looking for facet marks that are only seen in natural diamonds.
A polariscope is used to detect double refraction in a stone. This can tell you immediately whether the diamond is real.
A densimeter is a tool used to measure the density or specific gravity of a stone. Diamonds have a much higher density than other stones like quartz and glass, which will help confirm the stone’s authenticity.
Finally, microscopes are used to evaluate the diamond’s inclusions. Real diamonds have imperfections and inclusions that are messy and jagged. Fake diamomds, however, have more linear inclusions that look like scratches.
Does moissanite go off on a diamond tester?
No, moissanite does not go off on a diamond tester. Moissanite is a lab-created gemstone made from a mineral called silicon carbide, which has similar properties to diamonds but is not a diamond. Diamond testers specifically detect the thermal conductivity of diamonds, which is significantly different than that of moissanite.
Consequently, moissanite will not activate the diamond tester.
Are moissanite testers accurate?
Moissanite testers can be accurate in some cases, but they are not always 100% reliable. When it comes to identifying moissanite, experts recommend the use of multiple testing methods in order to be certain.
There is a specific type of tester referred to as a dual tester that is designed specifically to identify moissanite, and it is generally considered the best instrument for testing these stones. In addition to a dual tester, XRF and Raman spectroscopy are often used to confirm the presence of moissanite in a gemstone.
However, it is important to note that even with these methods, there is still the possibility of a false positive, so it is always best to take the stone to a qualified gemologist and have it tested professionally.
Can I pass off my moissanite as a diamond?
No, you cannot pass off a moissanite as a diamond. While moissanite shares some physical characteristics with diamonds, it is a separate gemstone. Moissanite is made of silicon carbide, while diamonds are made of carbon.
Moissanite is vastly cheaper than diamonds, and is usually distinguished by professional jewelers by its more “mirror-like” sparkle. Additionally, advanced diamond testers and trained eye of experienced jewelers can easily determine the difference between a diamond and a moissanite.
Therefore, it is not recommended to pass a moissanite off as a diamond.
Can a jeweler tell if moissanite is real?
Yes, a jeweler can tell if moissanite is real. Moissanite is a lab-created stone with a high refractive index that closely resembles diamond, so it can be difficult to distinguish from a diamond without proper testing.
Jewelers use a number of methods to authenticate moissanite, including visual inspection, microscope inspection, thermal conductivity test, performance test, and spectroscopic analysis. Visual inspection is used to identify the shape, size, and cut of the stone, as well as to check for any imperfections or blemishes that could indicate that it is not a real diamond.
Microscope inspection is used to observe the reflections, refractions, and dispersions that contribute to the sparkle and brilliance of the stone when it is viewed under magnification. Thermal conductivity tests measure the amount of heat that is passed through the stone to determine if it is a real diamond.
Performance tests check how the stone responds to light and heat, as well as how it interacts with light when viewed from different angles. Spectroscopic analysis is used to determine the makeup of the stone, as diamonds and moissanite have distinct spectral patterns.
Jewelers can therefore use a combination of these tests to accurately determine the authenticity of moissanite.
What is the downside of moissanite?
The main downside of moissanite is that, unlike diamond, it is not as hard and is not as resilient. Moissanite has a lower Mohs value (9. 25) compared to diamonds (10) which makes it more prone to chipping and scratching.
Additionally, moissanite can lose its sparkle and luster over time and may require more cleaning and polishing to maintain its shine. Moissanite is also not as rare as diamonds and therefore may not hold as much value as a diamond would.
Additionally, moissanite may have a slight “rainbow” or “oil slick” effect that can distract from its overall brilliance and rarity. Lastly, due to its lower weight (it’s about 10% lighter than diamond), it can easily be confused for diamond simulants or even fake diamond.
Do moissanite sparkle as much as diamonds?
When it comes to moissanite and diamond sparkle, it’s important to note that both gems have their own unique differences in terms of shine, fire, and brilliance. In comparison to diamonds, moissanite is famously known for having a higher fire and brilliance, meaning this gem will often have more visible flashes of rainbow-colored light and better overall sparkle.
However, when placed alongside a diamond of equal size, the diamond may appear to have slightly more flash and sparkle. This is because of its superior refractive index, which means more light is reflected off the surface of the diamond.
That being said, for those with a discerning eye, both moissanite and diamond will appear to sparkle brilliantly, with moissanite having its own unique appeal.
Why is some moissanite cheap?
Some moissanite is cheap because it is made with lower quality materials and/or lab-created rather than mined. While moissanite is already far less expensive than diamonds, lower quality materials and lab-created stones reduce the cost even more.
Lab-created moissanite is essentially an exact replica of a natural moissanite, and while the quality is still high, it is less expensive because the stones do not have to be mined and it can be made in much larger quantities.
Lower quality moissanite usually has fewer facets, a noticeable yellow hue, or slightly cloudy appearance when compared to higher quality stones. For those looking for a sparkling gemstone on a budget, lower quality moissanite is an economical choice.
Does moissanite pass the fog test?
Yes, moissanite does pass the fog test. The fog test is a widely used method of determining if a gemstone is real or simulated. To do this test, the gem is heated, either by the natural warmth of one’s hands or by a gemological heat tester.
Once the gem has been heated, the gemstone is breath on; when the breath is gently blown on the stone, it should form a fog. If the fog remains on the stone for a few seconds, the gemstone is considered to be real.
Moissanite has a high thermal conductivity, which means it takes on heat quickly and cools quickly, resulting in a fog that remains on the stone for a few seconds and passes the fog test.
Are rubies as valuable as diamonds?
No, rubies are not as valuable as diamonds. This is because diamonds are much rarer than rubies, which makes them much more sought-after and expensive. Diamonds are also much harder than rubies, allowing them to stand up to wear and tear better.
As a result, diamonds often retain their value better than rubies over time. Additionally, diamonds can be cut to create a vibrant sparkle, whereas rubies tend to have a more muted sheen. This tends to make diamonds more appealing to buyers and therefore more valuable.
In summary, rubies are lovely gemstones but generally not worth as much as diamonds.
How do you test a ruby?
Testing a Ruby application is an essential step that helps ensure that the code is correct and bug-free. There are various approaches to testing, such as manual testing, unit testing, and automated testing.
Manual testing involves manually testing the application by running through the various functions and features. This includes entering data manually and testing how the system behaves.
Unit testing is a form of automated testing that checks the correctness of a piece of code. In unit testing, each piece of code (or unit) is tested in isolation. This ensures that the code is performing correctly and that no bugs are introduced when changes are made.
Automated testing makes use of tools to test the application, such as Cucumber, RSpec, and Capybara. These tools automate the testing process and allow for quick feedback on the application’s behavior.
Automated tests can either be written in Ruby or with tools that allow you to write tests in other languages like JavaScript or Python.
No matter which method you choose, testing a Ruby application is important for the stability, security, and overall quality of the codebase.
