The cost to test a diamond depends on the type and extent of the test. Generally, a basic diamond evaluation – also known as a diamond grading report or certificate – ranges in price from approximately $50 to $250.
These evaluations, which are typically conducted by diamond grading laboratories such as the Gemological Institute of America (GIA), provide a detailed report of the diamond’s 4Cs – carat weight, clarity, color and cut – as well as other characteristics such as fluorescence and symmetry.
More extensive diamond testing, such as for quality control, may be necessary for some manufacturers and retailers, and could cost anywhere from several hundred to several thousand dollars, depending on the test and the laboratory chosen.
Synthetic diamond testing is even more expensive, and may cost several thousand dollars per stone if a specialized diamond tester is needed. Additionally, specialized alternative light source testing for lab-created diamonds can cost anywhere from hundreds to thousands of dollars depending on the number of diamonds that need to be tested.

Do jewelers charge to test diamonds?
Yes, most jewelers will typically charge for testing a diamond to confirm its authenticity and/or grade. Depending on the shop and their policies, this charge can range from a few dollars for a simple visual inspection, to a few hundred dollars for a full report from a certified gem laboratory.
The cost of diamond testing is usually separate from any other services the jeweler provides – such as a cleaning or repair – and is determined on a case-by-case basis. It is typically based on the size, quality, or other unique characteristics of the stone, or the type of testing desired.
It is important to inquire as to the cost of testing before any work is performed, as well as to make sure any testing is being done by a reliable source. Additionally, the cost of diamond testing can be recouped if the diamond is an investment or a valuable family heirloom, as it can increase the stone’s resale value.
How can you test to see if a diamond is real?
One common method used by jewelers is to check for color reaction. If a diamond is real, it will typically reveal a bright blue color when exposed to ultraviolet light. The same test can often reveal a yellow color when applied to a fake diamond.
In addition to the color test, the diamond can be tested with a loupe or microscope. A real diamond will often have double refractive features that are visible under magnification, which will not be visible on a fake diamond.
Another popular test for determining a diamond’s authenticity is with a fog test. When breath is applied over a real diamond, the fog should disperse quickly. On the other hand, a fake diamond will maintain the fog for a longer period of time before it dissipates.
Finally, a jeweler may choose to conduct a fracture filling test to check for a diamond’s authenticity. A real diamond will typically be filled with a material like glass or plastic, while a fake diamond will not have those same materials filling any of its facets.
Who can test my diamond?
A gemologist or gemologist-in-training is the most qualified professional to conduct a certification test on a diamond. A gemologist will be able to assess the authenticity of your diamond, and may use a microscope to examine the stone and other tools such as a refractometer to measure its optical properties.
They will also be able to detect any signs of prior treatments or enhancements, as well as determine the grading parameters such as the cut, clarity, carat weight, color, and fluorescence. To ensure you are getting the most reliable assessment of your diamond, be sure to ask your jeweler which specific gemologist is conducting the test and what qualifications they have.
The American Gem Society, for example, administers a randomized proficiency exam to its members to ensure their proficiency in their field. Ultimately, a gemologist is best qualified to evaluate the quality of your diamond.
Do lab diamonds pass a diamond test?
Yes, lab diamonds do pass a diamond test. Lab diamonds are made in the laboratory, not in the ground like natural diamonds. They are engineered to have the same chemical, physical and optical features as natural diamonds.
Lab diamonds even have the same number of carbon atoms as mined diamonds and the same sparkle. However, the only way to be absolutely sure a diamond is lab-grown is by having a qualified gemologist or laboratory use specialized equipment and techniques to evaluate the diamond.
Lab diamonds should also include a report from a respected gemological laboratory like GIA or IGI, which will identify the diamond as being laboratory-grown.
Does it cost money to get a diamond ring appraised?
Yes, it costs money to get a diamond ring appraised. The exact cost will depend on the type and size of the diamond ring, the professional doing the appraisal, and the complexity of the appraisal. Generally, the cost of a diamond appraisal ranges anywhere from $50 to $150, although some appraisers may charge more.
You may also need to pay additional fees or be charged an hourly rate if your appraiser needs to do a complex analysis or have your diamond tested in a laboratory. You can contact potential appraisers in your area to get an estimate of the cost of the appraisal.
Additionally, you may be able to find a package deal that includes the diamond appraisal and certification from a reputable laboratory.
How much is a .03 carat diamond worth?
The price of a .03 carat diamond depends on a variety of factors, including its cut, clarity, color, and carat weight. Generally speaking, a .03 carat diamond with average clarity and average color will cost anywhere from $50 to $200.
The cut of the diamond can also affect the price, with better cuts costing more. Prices can also vary depending on the source, so it can be helpful to shop around to get the best price possible. Additionally, the size of the diamond can also be an important factor.
Smaller diamonds tend to be priced lower because they have less sparkle, but if the diamond is in a larger setting, the cost may be higher. Ultimately, the cost of a .03 carat diamond will depend on the individual characteristics of that particular diamond.
What stones will pass a diamond tester?
A diamond tester will only successfully identify diamonds and won’t work for any other type of stone. It works by measuring the thermal conductivity of the stone, as diamonds are excellent thermal conductors and other types of stone are not.
Stones that will pass the diamond tester include white diamonds, fancy color diamonds, colorless diamonds, and moissanite. All natural diamonds are composed of the same elements and minerals, so they will all pass the diamond tester.
However, flux-grown moissanite creates some confusion because it also tests as a real diamond. A more advanced diamond tester may be able to differentiate between them by using both thermal conductivity and electrical conductivity.
Cubic zirconia is a synthetic diamond made out of zirconium dioxide, and it will not pass the diamond tester.
Is a diamond tester worth it?
A diamond tester is an important tool for jewelers and gemologists that can authenticate whether a gemstone is a diamond. Investing in a diamond tester is an important decision and can be worth the money if you are an experienced gemologist or if you are in the jewelry business.
Not only can a diamond tester confirm if a stone is a diamond, it can also provide information about the diamond’s characteristics such as clarity, carat weight, and color.
If you are a new jeweler or gemologist, then purchasing a diamond tester may not be financially worth it if you are not using it often. It is possible to purchase diamond testing services from third-party services or expert gemologists that can provide accurate results.
Overall, a diamond tester can be worth it, depending on your experience level in the industry and if you are able to use the technology on a regular basis. It is a valuable tool for jewelry stores and professional gemologists that can help to quickly and accurately authenticate a diamond.
Can a diamond tester tell the difference?
Yes, a diamond tester can tell the difference between a real diamond and a fake diamond. Diamond testers use a thermal probe to measure the properties of a diamond. The thermal probe will measure the diamond’s thermal conductivity, which is essentially the capacity of the diamond to conduct heat away, and also its characteristic electrical resistance.
Real diamonds will have a much higher thermal conductivity than fake diamonds and they will be much more resistant to electricity. Furthermore, some diamond testers will also utilize a hydrostatic weighing method to test the density of the diamond which can also help to distinguish the difference between a real and fake diamond.
All in all, a diamond tester can be used to accurately determine whether a diamond is real or not.
Are cheap diamond testers reliable?
The reliability of cheap diamond testers really depends on the specific model and how experienced the person using the tester is. Generally speaking, a cheap diamond tester is not as reliable as a professional grade diamond tester that is more expensive, because it is not as sensitive to identifying subtle physical characteristics in a diamond that can be an indicator of authenticity.
In other words, a cheap tester may not be able to pick up on certain properties that a more expensive model would, making the cheap tester less reliable.
That said, if you have experience with diamond testing and have a good knowledge of what is authentic and what isn’t, a lesser quality tester may still serve the purpose. However, if you are looking to purchase diamond jewelry, it is generally recommended to invest in a higher-grade diamond tester that can detect the properties more accurately and is more reliable in its results.
Can a jeweler tell if a diamond is lab created?
Yes, a jeweler can usually tell if a diamond is lab created. This is because lab created diamonds have certain characteristics that are different from natural diamonds. For example, lab diamonds usually have a higher level of nitrogen, which can be seen with the use of a microscope.
Lab created diamonds also often have distinctive color characteristics, such as a yellow or greenish tinge, which can help the jeweler differentiate them from natural diamonds. Additionally, jewelers can use advanced techniques, such as fluorescence tests or spectrometer use, to identify lab created diamonds.
What color does a diamond tester turn if it’s real?
A real diamond will cause a diamond tester to turn either green or a shade of yellow. The color indicates that the stone has a higher thermal conductivity, which is a quality that is unique to diamonds.
The color may also vary depending on the type or quality of the diamond. For example, colorless diamonds will often produce color ranges between light yellow and yellow-green, while fancy color diamonds may turn blue or purple.
The slight difference in reaction is based on the fact that certain colorless diamonds contain nitrogen atoms in their crystal structure, which affects their thermal conductivity.
How well do diamond testers work?
Diamond testers are optical instruments that can generally distinguish between a real diamond and other materials. They work by exploiting optical properties unique to diamond, such as fluorescence and dispersion.
Diamond testers use a process of elimination to distinguish between a diamond and other materials. They emit a beam of light through the stone and measure different properties of the light that is reflected back.
Diamond testers are generally accurate in distinguishing between a genuine diamond and other materials, including simulants. However, there are certain types of simulants (like Moissanite, for example) that can be harder to detect.
Additionally, diamond testers may produce a false-positive result when testing some synthetic diamonds, as they don’t always detect the difference between lab-created diamonds and mined diamonds.
Overall, however, diamond testers are an efficient and reliable tool to assess the authenticity of a diamond. Experienced gemologists generally have a good success rate at distinguishing between diamonds, simulants, and other materials with a standard diamond tester.
How can I test a diamond at home to see if it’s real?
Testing a diamond at home can be done in several ways. The first step is to look at the stone with a magnification tool such as a loupe. A real diamond will have distinctive features, such as tightly packed growth lines, while a fake diamond will have features that appear to be randomly scattered.
Additionally, a real diamond will typically have sharp edges, while a fake diamond might be rounded.
The second step is to try a breath test. Gently breath on the diamond and observe how the fog from your breath interacts with the stone. A real diamond will disperse the fog quickly, while a fake diamond will be slower to disperse the fog.
The third step is to perform a dot test. Take a sharp-pointed object such as a paper clip and apply gentle pressure to the stone. A real diamond should be able to withstand the pressure without scratching or leaving a mark, but a fake diamond will likely scratch or leave a mark.
Finally, for a more definitive test, consider taking it to a professional jeweler or gemologist. In most cases, they will be able to quickly and accurately determine if the stone is real or fake.
