Frequently Asked Questions

What diamond tester do jewelers use?

There are a few different types of diamond testers on the market, each with their own advantages and disadvantages. The most important thing to remember when choosing a tester is that it should be able to accurately distinguish between diamonds and other materials, like moissanite or cubic zirconia. One type of tester uses an electrical current to measure the conductivity of the stone being tested.

Diamonds are excellent conductors of electricity, while moissanite and cubic zirconia are not. This method is very accurate, but it can take some practice to get a consistent reading. Another popular type of diamond tester uses ultraviolet light.

Diamonds will fluoresce under UV light, while other materials will not. This method is quick and easy to use, but it requires a dark room in order to get an accurate reading. The best way to choose a diamond tester is to ask your local jeweler for recommendations.

They will be able to point you in the direction of a reliable tester that will suit your needs.

Are diamond testers any good?

If you’re considering buying a diamond, it’s important to do your research to ensure you’re getting the best possible value for your money. One way to do this is by using a diamond tester. But are these devices any good?

Diamond testers work by measuring the electrical conductivity of a stone. Because diamonds are extremely good conductors of electricity, they will register as “conductive” on a tester. However, other stones such as moissanite and cubic zirconia can also register as “conductive” on some testers.

So, while a tester may be able to tell you if a stone is a diamond or not, it’s not always 100% accurate. There are different types of diamond testers on the market, ranging in price from around $30 to $300. The more expensive models tend to be more accurate than the cheaper ones.

However, even the best testers can sometimes give false readings. The bottom line is that diamond testers can be useful tools when buying diamonds, but they’re not perfect. If you’re really serious about getting the best value for your money, it’s worth doing some additional research beyond just using a tester.

Can you trust diamond testers?

If you’re in the market for a diamond, it’s important to do your homework and be as informed as possible about the stone you’re considering. With all of the different ways to test diamonds out there, it can be tricky to know which method to trust. Here’s a breakdown of some popular diamond testers and whether or not they’re reliable.

Optical Diamond testers use light refraction to analyze a diamond’s clarity. This method is generally considered to be accurate, but it can sometimes give false positives for stones that have been treated with certain chemicals. Thermal Diamond Testers work by measuring the rate at which a diamond conducts heat.

Again, this method is usually pretty accurate, but there are some fake diamonds on the market that will pass this test. Electronic Diamond Testers measure electrical conductivity to determine if a stone is real or not. This method is also considered to be fairly reliable, although some fake diamonds will pass this test as well.

Pencil Lead Test The pencil lead test is a home-based way to test if a stone is real or not. Simply take a piece of pencil lead and scratch it across the surface of the diamond in question – if the mark left behind is white then congrats, you’ve got yourself a real diamond! However, this method isn’t always foolproof as some other materials (like quartz) can also leave behind a white mark when scratched with pencil lead.

So, what’s the best way to test a diamond? Unfortunately, there’s no one definitive answer – it really depends on what type of tester you’re using and what kind of fake diamonds are out there on the market. If you’re unsure about which testing method to trust, your best bet is probably to consult with an experienced jeweler who can help guide you through the process.

Will lab diamonds pass a diamond tester?

The answer is yes, lab-grown diamonds will pass a diamond tester as they are real diamonds. However, some testers can tell the difference between a natural diamond and a lab-grown one. Lab-grown diamonds are created in a controlled environment, using either high pressure and high temperature (HPHT) or chemical vapor deposition (CVD).

HPHT lab-grown diamonds are made by subjecting a small carbon seed to intense heat and pressure inside a container of molten metal solvent. CVD lab-grown diamonds are made by depositing thin layers of carbon onto a substrate in low oxygen environment. Both methods result in an authentic diamond product that exhibits the same physical, optical, and chemical properties as mined diamonds.

In fact, most gemologists cannot tell the difference between CVD and HPHT grown synthetic diamonds without sophisticated equipment. So if you’re wondering whether those beautiful lab-grown earrings you just bought will pass the diamond tester at customs, the answer is probably yes!
