IGI created the credit card diamond reports used as tools to help sell diamond rings in national mall jewelers. As long as the jeweler uses the right technology, it’s possible to spot diamond simulants right away.ĬZs of high quality can look like natural diamonds without flaws, while lab-grown ones might show inclusions if magnified. IGI became one of the largest diamond grading laboratories in the world by serving major chain retailers. GCAL was founded in 2001 in New York City. diamonds are grown exclusively by the chemical vapour disposition (CVD) method and come independently certified with either an IGI or GCAL certificate. They also have an advanced instruments division founded in 2004. The IGI certificate currently accompanies most lab-grown diamonds. Stick with GIA and use this step by step process to cherry pick the best stone.
However, IGI got an early start on grading lab-grown diamonds. Its certification is not overly reliable. So what fake diamonds pass diamond tester? None. It has a relatively small impact on the diamond industry, particularly in the USA. As a result, it has inferior optical properties when compared to diamonds (like double refraction). Glass, on the other hand, is not gem quality: it’s an artificial material with no perfect cubic crystal structure. 2 ) Based on the market, ANY major diamond worth it's salt is going to GIA. IGI also grades synthetic diamonds on a commercial scale. IGI actually grades a significant amount of polished diamonds in the market and they are prevalent in Asian countries. After GIA, they are actually the 2nd most well-known lab in the world. WHY NOT GIA The GIA does not offer normal services for Laboratory-Grown diamonds. And finally, IGI is the International Gemological Institute that is based in Antwerp, Belgium. It belongs to the family of synthetic gems that are also called fashion or costume jewelry. 1) Sellers trying to convince buyers that their H/Si1 ( with a substandard report) is the same as a legimately graded diamond. Every Ethos laboratory grown diamond has been graded by the IGI or GCAL. When referring to a stone as a fake diamond, most customers talk about cubic zirconia (CZ) and glass.Ĭubic zirconia is a cubic, crystalline form of zirconium oxide and is often used as a diamond simulant. Also, Lab Grown Diamonds are conflict-free and cost-effective at the same time. On the contrary, they are as real as natural diamonds since they share the exact chemical, optical and physical properties. When lab grown diamonds are IGI or GCAL certified, it means that those manmade diamonds have the same physical, chemical, and optical characteristics as natural diamonds, and exhibit the same fire, scintillation, and sparkle. First, it’s important to mention that lab-grown diamonds are not considered as fake.
