Yep like I said, lower demand allow the customers to bargain for a better price. I didn't say all IGI was good, mainly the ones from their headquarters in Antwerp, and the love and co series which I have viewed.
When choosing less consistant labs, you not only have the lab branch before looking at the specs. Many people think all EGL diamonds are trash, but this is not true. Those from EGL HK are infact very good. Unfortunately most of the EGL diamonds we encounter are from other branches which are indeed less strict, as Hong Kong and China consume most of the EGL HK stones. In fact some signature stones of retailers in hk are only graded by EGL HK. Where as their normal stones are GIA.
Disclaimer, the following is just my opinion :
In fact since it is accepted that GIA is stricter in color and clarity and AGS is stricter in Cut and Light performance, would that mean that Cartier stones focus on color and clarity and not cut ? What happens if the same stone is certified by AGS, is it now focusing on cut and not color and clarity ? In the end it is still the same stone. Color, clarity and cut you can see for yourself with your own eyes using loupes and scopes. Yet when people walk in to a branded shop, how many will ask to see those images. Practically non, why ? The reason is simple.
When you get a branded diamond, you are paying for... the brand. Thats why it is called branded. Despite all their patented design etc, if you get a private jeweler to replicate a design and its well replicated, no one will know the difference, but YOU will know its a replicate. Its one of those I know mine the real deal so i feel good kind of things. Given the high premium people pay for these branded products esp brands like Cartier, they could easily have certified it with both labs but they don't, cos to their target clients this certification is more or less just a formality.
I still stand by the fact that IGI is an inferior certificate. Just search on the internet, and there are many articles that have done studies to prove that IGI does have weaker grading than GIA.
Ok, assuming you say EGL cert is good and the EGL cert coming from different countries have different standards, like EGL HK is better EGL US. (There are many articles banging EGL certs too) Isn't this very confusing? how can this happen in the first place? Isn't EGL the brand of the certificate? It's like saying Tiffany diamond rings in HK are better quality than Tiffany diamond rings in the US. GIA has labs in US and HK too.. But you don't see anyone saying that GIA HK certs are better than GIA US certs. If it's the same company, why is there differing standards? If there exist differing standards, it also reflects badly on the cert's reputation.. it shows that they have no quality control over their labs where their own labs produces different results. Why can't they keep it consistant?
GIA/AGS are more recognized internationally for their stricter grading system and are used as benchmarks. In the future, if you need to resell your diamond, a GIA cert diamond would retain the value better than a IGI/EGL.
So why do these labs like IGI and EGL exist if they are a lower tier? The answer is simple. PROFITS.
"The reason for a grading lab to give softer grades is to get more business from diamond manufacturers, retailers or wholesalers who want to increase their profits by selling diamonds given higher grades at higher prices."
