How can you tell if a lab diamond is real? 

Lab made diamonds uk are real diamonds, they are just created in a laboratory rather than being mined from the earth. So if you have a lab-grown diamond, it is real, but if you are trying to determine whether a diamond is lab-grown or mined, there are a few things you can look for: 

  1. Certification: A reputable lab-grown diamond supplier will provide certification from an independent diamond grading organisation, such as the Gemological Institute of America (GIA) or the International Gemological Institute (IGI). The certification will indicate whether the diamond is natural or lab-grown. 
  2. Price: Lab-grown diamonds are typically less expensive than mined diamonds of similar quality, so if the price seems too good to be true, it could be a sign that the diamond is lab-grown. 
  3. Colour: Lab-grown diamonds often have a different colour distribution than natural diamonds, so they may appear slightly different when viewed under certain lighting conditions.
  4. Growth lines: Some lab-grown diamonds may have growth lines or patterns that are not present in natural diamonds, although this is not always the case. 
  5. Weight and size: Lab-grown diamonds can be made in larger sizes than natural diamonds, so if the diamond is exceptionally large or heavy, it could be a sign that it is lab-grown.
  6. UV fluorescence: Some lab-grown diamonds may exhibit a different pattern of UV fluorescence compared to natural diamonds. A jeweller with a UV light can help you determine if the diamond shows any differences in fluorescence. 
  7. Magnification: You can use a jeweller’s loupe or a microscope to examine the diamond for inclusions, growth patterns, and other characteristics that are indicative of a natural diamond. 8. Electrical conductivity: Lab-grown diamonds may exhibit higher electrical conductivity compared to natural diamonds due to the presence of certain impurities. You can use a diamond tester that measures electrical conductivity to check if the diamond is lab-grown. 

One more thing to keep in mind is that lab-grown diamonds are becoming increasingly popular and widely available, and there are many reputable and ethical lab-grown diamond suppliers out there. If you are interested in purchasing a lab-grown diamond, you can do some research to find a supplier 

with a good reputation, and look for certification from a reputable diamond grading organisation. This can help you feel confident in your purchase and ensure that you are getting a high-quality, ethically sourced diamond. 

It is important to note that none of these methods are foolproof, and the best way to determine if a diamond is lab-grown or natural is to get it certified by a reputable diamond grading organisation. If you are still unsure, you can take the diamond to a reputable jeweller or gemologist for further analysis.
