Many jewelry lovers will always ask whether lab diamonds pass a diamond tester. Most people are left in the question dilemma and are always looking for the correct answer. At Martin Jewelry, we work with educated customers and customers seeking knowledge, believing that educated customers are happy customers. Therefore, we are proud to help you learn whether lab diamonds pass diamond testers to help you gain power with this helpful information.
Different diamonds are exposed to diamond testers to determine their thermal and electrical conductivity. Diamond testing is a term used mainly by gemologists and will leave many people with a question; do lab diamonds pass a diamond test?
Spare your valuable time to read what a diamond tester means exactly and whether lab diamonds pass diamond testers.
What Is A Diamond Tester?
Anytime you hear of a diamond tester, a “handheld pen tester” should come to your mind. The pen measures thermal and electrical conductivity. The testers usually have metal points that measure the speed of electrical current through the stone when exposed to the gem’s surface. Diamonds are well-known for their superconductivity; hence this method is appropriate to determine whether the stone is a diamond.
Will Lab Diamonds Pass A Diamond Tester?
Yes, lab diamonds have the same carbon composition as natural diamonds. Therefore, they have the same thermal conductivity. The test results are positive when exposed to the diamond tester, since the diamonds have the same physical and chemical properties as natural diamonds.
However, in some instances, lab-grown diamonds contain lower proportions of nitrogen than natural diamonds. They would give negative results in such instances, but this does not imply that the diamond is fake. Regardless of any outcome, you should know that lab-grown diamonds have chemical, physical, and optical properties like earth-mined diamonds.
Do All Diamonds Produce Same Results Under A Diamond Tester?
Lab diamonds and natural diamonds will produce similar results under a diamond tester. However, the results may vary in some lab-grown diamonds due to nitrogen composition. It is important to note that the two diamonds have similar chemical and physical characteristics, giving the same clarity, hardness, thermal, and electrical conductivity.

FAQs
Will Lab Diamonds Pass A Diamond Tester? Yes, lab diamonds have the same carbon composition as natural diamonds. Therefore, they have the same thermal conductivity. The test results are positive when exposed to the diamond tester, since the diamonds have the same physical and chemical properties as natural diamonds.
Can a jewelry appraiser tell if a diamond is lab grown? ›
The laser inscription can help determine whether it is a lab-grown diamond using a 30x jeweler's loupe.
Will a lab diamond pass a diamond tester? ›
Yes, lab-created diamonds will test as real diamonds. Their identical composition and characteristics to natural diamonds mean they pass standard diamond tests with the same results.
Can a jeweler recognize a lab created diamond? ›
Jewelers can tell if a diamond is lab grown through various gemological tests. They may use equipment like a DiamondView tester, which relies on a. Additionally, many jewelers work with accredited diamond grading labs who provide documentation, such as grading reports, confirming the origin of the diamond.
Can a CVD pass a diamond tester? ›
Yes sure All the diamonds/ Moissi will pass diamond tester 2, (most common tester). Mostly Lab created HPHT, CVD and many earth mined diamonds with the presence of boron, nitrogen and other impurities will test as moissanite on presidium and multi testers as well.
Can a pawn shop tell if a diamond is lab created? ›
Man made diamonds are difficult to spot because of their chemical, physical and optical properties similar to their natural counterparts. Professional jeweler services and pawn shop brokers often have the equipment needed to tell the difference.
Do jewelers have to disclose lab-grown diamonds? ›
The FTC does require full disclosure on the sale of any lab-grown diamond so for that reason, all lab-grown diamonds should be engraved with the letters “LG” for lab-grown.
Do lab grown diamonds get cloudy? ›
The simple answer is no – when produced by reputable manufacturers, lab diamonds do not get cloudy or change appearance. A general misconception is that lab grown diamonds are more likely to appear cloudy or contain color due to their artificial origin.
Do lab grown diamonds turn yellow? ›
Lab-grown diamonds do not turn color over time. They are stable and maintain their color as they are created to mirror the properties of natural diamonds, which are chemically and physically stable.
Are Costco diamonds lab grown? ›
All diamonds offered by Costco are natural and untreated. Colored gemstones are often enhanced in the production process. All colored gemstones offered by Costco have been enhanced unless otherwise stated.
Lab grown diamonds resale value
The resale value of a lab diamond ring will be around 30% to 40% less than you paid, and the same is true of a natural diamond ring - so be sure not to view this transaction as an economic investment! Instead, you're buying something beautiful that will bring endless joy, for a lifetime.
Do lab-grown diamonds sparkle rainbow? ›
Their shared optical properties, particularly dispersion, make lab-grown diamonds reflect rainbows identically to mined diamonds. Considering factors like shape, clarity, and hue when picking a laboratory-grown diamond ensures the perfect rainbow refraction.
Will a lab diamond fail a diamond tester? ›
Since lab grown diamonds are made of pure carbon and have the same thermal conductivity and chemical properties as mined diamonds, they will ALWAYS record a positive test on a diamond tester.
Are there fake diamonds that pass diamond tester? ›
Can fake diamonds pass diamond tester? Yes, some diamond simulants can pass a diamond tester. For example, moissanite, a man made gem, may pass as a diamond on a standard tester pen. This is because moissanite also has very high thermal conductivity!
Why did my lab diamond test as moissanite? ›
The reason for this unexpected outcome lies in the presence of boron, an impurity uncommonly found in natural diamonds but often present in laboratory-grown diamonds. Boron, when trapped within the diamond's crystal structure, alters its properties, notably affecting its colour and electrical conductivity.
How do I know if my diamond is lab grown? ›
Lab grown diamonds are chemically the same as mined diamonds, and one of the only ways to tell the difference is for a gemologist to look under a magnifier for a laser inscription on the girdle of the diamond and determine the origin.
Are lab-grown diamonds traceable? ›
Lab grown diamonds can be traced from start to finish. You can be confident that your lab grown diamond earrings are the product of scientists, with full traceability. With these diamonds you can be certain that your jewellery is conflict free, they are not 'blood diamonds'.
Can a gemologist tell the difference between lab-grown diamonds? ›
Because laboratory-grown diamonds are essentially chemically and optically the same as natural diamonds, traditional gemological observations and instrumentation are not able to tell them apart. GIA uses sophisticated devices like the GIA iD100® and other instrumentation to definitively identify natural diamonds.
Does GIA appraise lab-grown diamonds? ›
Yes. GIA has been grading laboratory-grown diamonds since 2007.
