Many colored gemstones and diamonds are graded and certified by a gemologist to guarantee their authenticity based on seller claims e. The 4Cs of diamond grading. A certified gemstone from a reputable seller offers more peace of mind to a buyer, but many times also comes with a higher price tag. If you have an existing stone, you can send it to a lab or bring it to a jeweler with gemologist on staff.
An analysis would uncover what it really is e. Fun Fact: Any type of gemstones can be a simulant. For example, a lab-created moissanite and genuine white sapphire are both diamond simulants; they both have the same clear appearance, but different composition than the diamond.
A brand name gemstone can be natural, genuine or synthetic, etc. The brand is typically registered or trademarked to provide name rights to the business, to help the consumer identify it and also to designate better-quality not always the case. As with most retail name brands, a brand name gemstone is typically priced higher than a non-branded equivalent.
Better is a VERY subjective term and your opinion may vary dependent on the type of gemstone you seek. If you are partial to buying jewelry crafted with a real and authentic stone for its value and natural properties, genuine should be your choice. If you have environmental concerns, lab-created stones are created in a controlled setting with few resources versus procured through an extensive mining process, which is typically followed by importation and other activities that result in a much larger carbon footprint.
On that note, keep reading for some more specific examples. Opting for the lab-created vs. This white gold emerald engagement ring SKU costs over 2. The alexandrite is a unique and rare, two-tone stone that costs less when lab-created. Although a sapphire is considered quite common and affordable in the grand scheme of gemstones, you can still save a bit of cash by opting for a lab-created version.

Hold the diamond in question under a normal lamp. Watch how light reflects off of the stone.
Do you see bright shimmers of white light bouncing off the diamond? Do you see colorful light reflections as well? A real diamond reflects white light extremely well, providing exceptional sparkle. Diamonds also reflect colored light, or fire, in magnificent fashion.
If you compare a real diamond to a fake diamond like Cubic Zirconia, you are able to notice a drastic difference in the white and colored light sparkle that the real diamond gives off. A professional gemologist who has a Graduate Gemologist GG degree will be able to tell you definitively if a diamond is real or not. Bringing your stone to a diamond professional will give you peace of mind, because several proven methods and tools are used to determine if a diamond is real.
A diamond professional will have access to a loupe—a special magnifying glass used for diamonds, gemstones and jewelry. When using a loupe, a professional will look for blemishes and imperfections within the diamond.
While a fake diamond can be perfectly constructed, a diamond will have small imperfections called inclusions. In addition to a loupe, gemologists usually have a thermal conductivity probe or meter. Because diamonds are effective heat conductors, the diamond will disperse heat rapidly after being warmed.
If the gemstone disperses heat at a slower rate, the diamond is not real. There are many diamond testers available out there, so you can choose whichever one you like the most. Check out an example from Amazon on the right.
Jewelers and gemologists usually have a very fine tuned scale for measuring small differences in weight. The weight of a real diamond will be lower than fake stones like the Cubic Zirconia—but only special scales for weighing Carats will be able to detect these minute differences. To perform the test, choose a fake diamond that is approximately equal in shape and size. Use this stone as a comparison for the diamond you are considering.
Detecting a fake diamond can also be achieved through a electricity conductivity test performed by a jeweler or gemologist. Diamonds conduct electricity better than other stones, including the difficult synthetic moissanite. An electricity tester will provide a clear sign as to whether or not the stone is real or created by a lab. A diamond will show conductivity while other stones like moissanite and cubic zirconia will not.
These tools can determine almost immediately if a diamond is real or fake. With a x magnification on a power microscope, a jeweler or gemologist is able to scrutinize the stone in detail. To have the internal, molecular qualities of a stone reviewed, send it to a professional diamond lab for testing. Their x-ray machines will be able to tell if the stone has a radiolucent molecular structure or a radiopaque molecular structure. Diamonds are radiolucent while fakes like cubic zirconium and crystals have more radiopaque features.
The test involved scraping the loose gemstone along a mirror to see if it would scratch the mirror or the stone. While a diamond is formed with very strong materials, fakes like cubic zirconia and moissanite are quite durable and scratch-resistant as well. For these reasons, the scratch test is not accurate. You are better served to use other tests such as a thermal conductivity test or having the diamond inspected with a professional loupe tool. With the rising popularity in other gemstones, here are some steps to spotting a stone that to the naked eye may appear similar to a real diamond.
Synthetic diamonds have similar chemical and molecular components to real, natural diamonds. Because of their intricate internal qualities, we recommend having the diamond reviewed by an expert.
They can run the conductivity test and look at the stone under high magnification. A cubic zirconia is one of the easier fake diamonds to test for authenticity. In addition, cubic zirconias reflect orange tinted light. Sapphires are commonly available in blue and a wide range of colors including white, which looks clear to the naked eye. Perhaps the best actor in the fake diamond world is the synthetic moissanite. Distinction between the two is usually difficult for the naked eye and requires the expertise of a diamond professional.
