Yes, a skilled jeweler should be able to tell a lab-created diamond from a natural diamond. Lab-created diamonds are typically made using two processes- HPHT or CVD. The look and feel of lab-created diamonds can be very similar to natural diamonds, but jewelers can look at a few difference that differentiate one from the other.
Lab-created diamonds tend to have fewer inclusions and blemishes than natural diamonds, and the inclusions can be smaller and more uniform. With the HPHT process, these diamonds often exhibit a yellowish hue that is not seen in natural diamonds.
Additionally, the facets can reflect light differently, showing rainbow patterns that are not detectable in natural diamonds. Jewelers can also use magnification and certain acid tests to further differentiate between the two types of diamonds.
How do jewelers know if a diamond is lab created?
Jewelers typically assess the origin of diamonds by looking through an array of characteristics, such as the origin of the diamond and its grading report. Lab-created diamonds must be marked to indicate their origin, as they are not from nature.
Lab-created diamonds are more carefully monitored in the production process, so there is an even higher degree of clarity and consistency than with naturally occurring diamonds. To assess whether a diamond is lab created, a certified gemologist or appraiser will conduct a visual inspection.
They can then infer the likely origin based on the type of cut, clarity and other characteristics. They can also use eco-friendly and non-destructive testing to confirm the diamond’s origin. With the introduction of lab grown diamonds, jewelers have developed new methods to differentiate them from mined diamonds.
This includes the use of cutting-edge technology, such as special equipment and scanners, in addition to microscopic observations. If in doubt, they can also opt to send the diamond out for testing to an independent laboratory, as lab-grown diamonds require a special certificate to identify their origin.
Are most lab diamonds marked?
Most lab-grown diamonds used by jewelers come with a certification clearly indicating they were created in a lab. Most major gemological laboratories use a laser inscription to denote a diamond is lab-grown.
This laser inscription is usually small and placed on the girdle (outer edge) of the diamond. It will look like “LG” and the report number. Some labs, such as Gemlogis, may also include a unique tracking number right on the diamond so you can verify its origin and grading report.
But not all lab-grown diamonds are marked. It is still important to check the accompanying grading report and shop from trustworthy vendors so you can be certain you are purchasing lab-grown diamonds.
Do lab diamonds hold their value?
Yes, lab diamonds do hold their value. Lab diamonds are diamond simulants that have the look and feel of a real diamond, without the expense. They are made in a laboratory, so it is possible to manufacture lab diamond better than what is naturally found in the earth.
Lab diamonds are also created using a different grading system, with the grading lab diamonds to be more consistent in the size and quality over time than mined diamonds.
The resale value of lab diamonds is noticeable. Lab diamonds can be re-sold for a better rate than what people often pay for mined diamonds. Lab diamonds may retain more of their original purchase value as well.
As a result, lab diamonds can be a great investment due to their ability to hold their value over time.
On the flip side, lab diamonds are often not certified and therefore they don’t have reliable documentation to show their value. They may also not be made with the same attention to detail that most mined diamonds are.
In the end, while they may hold their value, lab diamonds may not always fetch the same value as a certified and cut mined diamond.
How can you tell if a diamond is real at a pawn shop?
If you are looking to determine whether a diamond is real at a pawn shop, there are several key steps you should take to assess its authenticity. Firstly, you should always ask to view the diamond in natural light in order to assess its sparkle and color.
You should also look for signs of fluorescence or examining the clarity, as well as having the stone inspected by an independent, certified appraiser. Additionally, you should ask to see the paperwork associated with the diamond to ensure that it is genuine.
Look for a ‘certificate of authenticity’ or a ‘report card’ which can help you assess the grade of the diamond. When assessing the quality of a diamond, you should also assess the 4 C’s: cut, clarity, colour, and carat.
Finally, you can ask a professional to assess the diamond’s authenticity with a gemstone tester, which can potentially indicate if the diamond is real.
Why do lab grown diamonds have no resale value?
Lab grown diamonds have no resale value because they are artificially made and not considered a valuable commodity. Lab-created diamonds lack the characteristics that make natural diamonds highly sought-after, namely rarity and the substantial amount of time it takes to form them underground.
As a result, lab-grown diamonds are more likely to be viewed as “fake” stones and are not seen as an investment like natural diamonds, which hold their value and often appreciate in value over time. Furthermore, most buyers of diamond jewelry prefer natural diamonds because of their perceived uniqueness and rarity.
Can you tell the difference between lab grown and mined diamonds?
Yes, it is possible to tell the difference between lab grown and mined diamonds, though it can sometimes be difficult. Lab grown diamonds are created in a laboratory using technology that replicates the conditions and elements used in the formation of natural diamonds, creating identical physical and chemical properties.
Mined diamonds are created naturally in the environment and the materials and temperatures used when creating the diamonds are out of humans’ control.
The biggest difference between lab grown and mined diamonds is likely their price. Lab grown diamonds cost around 20-30% less than their mined counterparts, as the process to create them is both faster and less costly.
Lab grown diamonds do have one aspect that is of greater value than a mined diamond—they are eco-conscious diamonds, meaning they have a much lower environmental impact since the process for creation does not create any negative environmental consequences like mining does.
Lab grown diamonds are also growing in popularity as they have earned the same authenticating certifications that mined diamonds receive.
Visually, lab grown and mined diamonds can look near identical, so one must turn to the grading documents to determine if it is a lab grown or mined diamond. A lab grown diamond will come with a creation report from the laboratory that states that it is a lab grown diamond and additionally, the lab will laser-inscribe the gem with a unique identification.
For mined diamonds, they will receive a grading report with analysis of the stone, instead of a “creation report. ”.
How do lab diamonds get appraised?
Lab diamonds typically get appraised much like any other type of diamond. A qualified gemologist will inspect the diamond and assess its quality and value by examining its carat weight, color, clarity, and cut.
The gemologist will inspect the stone thoroughly under magnification to determine its clarity, examine its color with a color grading scale, assess its cut based on the proportions and symmetry of its facets, and weigh it to determine its carat weight.
Depending on the type of lab-created diamond, the gemologist may use different tools and techniques to assess the stone, as lab-created diamonds typically have features that require specialist instruments and techniques to evaluate.
Once these characteristics have been determined, the gemologist will then assign a value to the diamond by comparing similar diamonds within their market.
Why are jewelers pushing lab grown diamonds?
Jewelers are pushing lab grown diamonds for a variety of reasons. Firstly, lab grown diamonds provide an ethical and sustainable option for consumers looking for an alternative to traditionally mined diamonds.
Secondly, lab grown diamonds are much more affordable than mined diamonds, making them a more attractive option for people on a budget. Finally, lab grown diamonds are identical to natural diamonds in terms of their appearance, cut, and clarity, meaning they can be used to produce virtually indistinguishable pieces of jewelry.
For these reasons, lab grown diamonds are becoming increasingly popular amongst jewelers and their customers alike.
What are the disadvantages of lab grown diamonds?
The primary disadvantage of lab grown diamonds is their cost. They are usually much more expensive than naturally mined diamonds of comparable quality and size. Additionally, there might be a social stigma attached to lab-created diamonds, since many customers still prefer naturally mined diamonds.
Another potential disadvantage of lab-created diamonds is their durability. Lab-grown diamonds tend to be less hard than natural diamonds, which means that they may chip or wear down faster than natural diamonds.
This means that lab-grown diamonds do not have the same level of investment value as a natural diamond, as they will not maintain their value over time as well.
Finally, while they are often similar in appearance to natural diamonds, lab-created diamonds are not unique and are produced in a laboratory setting. Because of this, lab-created diamonds will not have any of the natural inclusions that occur in naturally mined diamonds that make them so special and unique.
Will lab diamonds be worthless?
No, lab-created diamonds are not worthless. In fact, they are becoming increasingly popular among consumers who are drawn to their affordability, ethical production, and environmental benefits. Lab-created diamonds are made with precision and attention to consistency, improving their quality and creating a product that is closest to mined diamonds.
While lab diamonds may not have as much sentimental value as mined diamonds, their composition, value, and properties(including longevity, near-perfect clarity, and cut) are comparable to natural diamonds, meaning they are anything but worthless.
Will a lab diamond go off on a diamond tester?
No, a lab-created diamond will not go off on a diamond tester. Diamond testers are designed to detect the physical properties of a diamond such as its carbon structure. Lab diamonds, however, are not composed of carbon but instead of a synthetic material that replicates the optical and physical qualities of a diamond.
The chemical makeup of a lab diamond is such that it does not emit any of the electrical impulses used by diamond testers to distinguish a real diamond from other types of stones. Therefore, lab diamonds will not be detected by a diamond tester.
How do pawn shops check diamonds?
Pawn shops that accept diamonds typically use experts to verify a diamond’s authenticity and appraise its worth. First, an expert jeweller or gemologist examines the diamond for its four Cs – carat, colour, clarity, and cut.
They use a special tool called a diamond gauge, which measures a diamond’s size and tells whether it is an authentic gemstone. After the diamond passes this initial inspection, the gemologist may use a microscope to further examine the stone’s inner characteristics.
Additionally, pawn shops may use a black light to check for irradiation, synthetics, simulants, or treatments. Other methods used in verifying diamonds include testing the stone with a refractometer or using a spectral machine to identify the colour of a diamond.
Finally, the stone’s appraised value will be based on the size, quality, and rarity of the gem.
